3D Wayfinder team will travel to Barcelona for Integrated Systems Europe (ISE) in February 2026. Our CEO will lead the visit, and we’ll use the event to meet partners, exchange insights, and discuss next steps for upcoming projects. ISE 2026 takes place on 3–6 February at Fira de Barcelona Gran Via.

This year, we won’t exhibit with our own booth. Instead, we’ll focus on meetings and meaningful conversations—both with existing partners and with new teams interested in collaborating. If you’re attending ISE and would like to meet 3D Wayfinder team, get in touch and we’ll schedule a time that works.

Let’s meet in Barcelona

Message us before the event (or during it) and share your availability. We’ll gladly visit your stand, grab a quick coffee near Fira Gran Via, or meet on the show floor. Since the show runs Tuesday to Friday it helps to schedule meetings early.

Piusa’s sandstone tunnels are one of South-Eastern Estonia’s most striking natural heritage sites-shaped by decades of glass-sand mining and now protected for their unique bat-friendly microclimate. Since the caves have been closed to the public due to collapse risk, experiencing this underground world has long been limited to stories and photographs. This project changes that by delivering a 3D model of Piusa Caves that captures the scale, textures, and atmosphere of the tunnels in high detail, allowing visitors to explore the cave system virtually and safely through an interactive application.

The Piusa Sandstone Caves

Between 1922 and 1966, miners extracted glass sand in Piusa and created an extensive underground network of sandstone pillars and vaulted chambers. The tunnel system extends for approximately 20 kilometres, and the unique environmental conditions have made the Piusa caves the largest hibernation site for bats in the Baltic region. For this reason, the area is under nature protection.
The caves once welcomed visitors, but authorities permanently closed them to the public in 2006 because of a collapse risk. Despite this, the Piusa Visitor Centre has become one of the most popular tourist attractions in South-Eastern Estonia.

Modern technology has made it possible to bring this heritage closer to visitors once again. In cooperation with the Piusa Visitor Centre, Võrumaa Development Centre, Võru Municipality, Maperions, and the Estonia–Latvia Interreg programme, a project was launched with the goal of creating an accurate 3D model of approximately 1.2 km² of the Piusa cave system. Through a dedicated application, visitors can now explore the caves virtually.

Our experienced 3D Wayfinder team completed the work. We had previously mapped smaller cave sections with laser scanning. This time, we captured the entire cave system with a different methodology.

Choosing Photogrammetry

The aim was to create a model that was as precise and detailed as possible. After careful evaluation, we chose photogrammetry as the most suitable method for mapping such a large, complex environment. Photogrammetry enables the creation of 3D models from a large number of aligned images and offers high accuracy, while also capturing the natural colours and textures of the caves.

We used dedicated software to align images and generate the model. For this project, we used the professional version of Agisoft Metashape, which also supports 360° panoramic images. However, achieving reliable results required overcoming several challenges—the first being proper lighting conditions.

Photogrammetry requires uniform, diffused lighting that remains consistent throughout the entire capture process. Naturally, such conditions do not exist in caves. To solve this, the Wayfinder team divided the cave into manageable sections using hand-drawn sketches and historical cave maps. Each section was photographed individually, illuminating only one area at a time.

Power was supplied via one fixed electrical outlet, two large battery stations, and approximately 20 construction lights.

Image Capture Workflow

With the section-by-section lighting approach, we photographed the entire cave system using an Insta360 camera on a tripod. We followed a systematic workflow. After installing lighting for a section, the team moved along a pre-planned route, positioned the camera, and captured three images using Automatic Exposure Bracketing (AEB) through a connected mobile app. This produced highly detailed DNG files suitable for further processing.

Because we had to trigger the camera near its position, we had only 5–10 seconds to move out of sight behind a pillar after starting the capture. Each AEB sequence took approximately 15 seconds. Once the app confirmed that the images were taken, the camera was moved forward by roughly 1.5 metres, the position was marked on a sketch, and the process was repeated. During breaks, we checked memory capacity and battery levels.

Using 360° images reduces the number of images needed and allows capture from a single height. Under the given conditions, this proved to be the most efficient approach. Under these conditions, the team found this approach the most efficient. In total, they captured about 1,200 images. The lighting and photography process took 52 hours in the cool, humid cave environment, a challenge the Wayfinder team embraced without hesitation.

Model Creation

High-quality images are essential for creating a high-quality model, but the next major challenge was preparing this large dataset for processing. For each capture position, we merged the three AEB images into one image. We also colour-balanced the result to keep each section consistent.

Model creation was carried out in Agisoft Metashape. Images were organised by area and processed section by section, combining multiple sections where possible to achieve a more cohesive result. In total, the cave model consisted of 16 sections. Each section went through the following stages: image alignment, point cloud generation, and 3D mesh creation.

Due to challenging lighting conditions, the initial models were not perfectly clean. Therefore, the meshes were exported to external 3D software for manual cleanup, correction, and geometry optimisation. It was crucial to maintain the exact coordinate alignment used in Agisoft, as all image alignment was based on this coordinate system. After refinement, we imported the models back into Agisoft. Then generated textures from the aligned images to match the real cave environment as closely as possible.

After all 16 sections were completed, they were carefully assembled into a single coherent model. Using working sketches and distinctive cave features as references, overlapping areas were trimmed where better results existed in other sections. These aligned, textured sections formed the basis for all subsequent steps.

Final Model and Virtual Experience

The Agisoft models delivered high detail, but they also produced extremely large files. Each section ranged from 80 to 250 MB in size, while the final application required the entire cave model—including textures—to remain around 100 MB for optimal performance. This meant reducing the data size by approximately 90% without compromising visual quality.

We achieved this by transferring high-polygon detail onto a low-polygon model using normal maps. First, we merged all sections into one high-detail model. Then created an optimised low-polygon version and added UV mapping. Normal map baking and texture transfer preserved the appearance of the high-detail model while dramatically reducing file size.

We deployed the final model on the 3D Wayfinder platform. We added navigable paths, a user interface, and animated bats. Visitors can now safely explore the otherwise inaccessible cave system on a large interactive screen, experiencing a unique natural heritage site through virtual technology.

3D Technologies R&D is delighted to share great news: young motocross rider Martha Koort was crowned the 2025 summer season Estonian champion in the Arctic Sport MX Masters Women’s class. At the season finale in Lange, Martha Koort did exactly what a title run demanded – kept her cool, took the decisive win, and secured the top spot in the standings. According to the Estonian Motorcycling Federation’s summary, she collected 222 points over the season, finishing ahead of her closest rival, Rita-Liisa Mooses.

Koort’s championship campaign got off to a strong start already in early spring. With relatively few hours on her new, larger bike, she won the opening round in Kiviõli. At the second round in Karksi-Nuia, a crash meant settling for fourth and second places. Valuable points that kept the title fight on course. These early rounds showed both speed and consistency, qualities that proved essential later in the season.

Her summer form was confirmed by several other showings. She took convincing wins at the third and fourth rounds in Tihemetsa and Pärnu. At the ENKV Round 7 held in late August in Linnamäe, she won both motos and claimed the overall with maximum points, underlining that her championship pace was no coincidence. Throughout the season the main challengers pressing Koort were Rita-Liisa Mooses and Elisabeth-Mary Vainrauh.

The title decider at Lange brought one last spike of tension. In qualifying, Mooses set the pace, in the first round, Koort played it slightly safer after receiving penalty points. In the second round, however, she took matters into her own hands – grabbing the lead from the first lap, winning convincingly, and with it securing the Estonian championship. EMF’s official final classification, Martha finished with 222 points, Mooses with 214, and Vainrauh with 178.

3D Wayfinder’s role

3D Wayfinder’s role on this journey was to be Martha’s partner, not just a spectator. We supported the season so that the young rider’s focus could stay on the track rather than on spreadsheets. We also gifted her an Insta360° camera so she can film her rides in the future, analyze lines and trajectories, and share the best moments with fans. This kind of visual “telemetry” helps get the most out of training days and brings authentic perspectives to social media that can inspire other young riders as well.

This partnership is inspiring for us. 3D Wayfinder helps people “find their way faster,” and on track Martha is always searching for the most efficient racing line. Just as great wayfinding makes a large building intuitive, high-quality data and consistent feedback make speed manageable. We believe a young athlete’s success happens when technology, support, and work ethic move in the same direction – and the 2025 championship title is the best proof of that.

Congratulations, Martha! Thank you for the emotion, speed, and perseverance. We will continue to stand by your side so that every next start gate opens with confidence and a clear plan – whether the goal is an Estonian, Baltic, or European podium.

3D Wayfinder cooperates with large shopping malls, airports, train stations, universities and other similar institutions on a daily basis. In most cases, we do not deal with projects with seven rooms and the floor area of ​​that is proportional to a typical single-family residence. However, this project is personally special and much more important than it seems at first.

Sorority Amicitia is founded in Tartu, Estonia. This November, Amicitia celebrated its 100th anniversary. As part of the jubilee celebrations, the Amicitia exhibition “A Century Under the Lilac Sorority Cap” is held in the library of the University of Tartu. As part of the exhibition, 3D Wayfinder made a Premium 3D model of the building of Sorority Amicitia.

Premium 3D Model and First Person View

Premium 3D model was chosen because it was important to bring out very precise details. The model is more of a sight in itself than a wayfinding tool. The value of this model lies in the abundance of small details. Nevertheless, the model also has a wayfinding function. This time we decided to try a FPS (first person view), instead of the classic wayfinding top-view for path visualization. For this kind of project, the “First Person View” works perfectly and brings good -real life kind of emotions.

Clickable Billboards and Pop-up Windows

Floating billboards that are clickable are use to mark the rooms. Also billboards are always facing towards user/camera. In addition, when you click on the billboard, a pop-up modal window appears with text describing the room. Such a solution was important, because house tours are usually held in these rooms to present Amiticia’s activities. The text in the Pop-Ups is similar to the text spoken during the tours.

In addition to the locations of the rooms, the locations of various things are tagged in the model. The model has several furniture items that are model in more detail. The most important items are add as POI (point of interest) and are also located in the menus. It is also possible to find a way to them. When you click on an item in the menu, it will flash gold and dark green (this can be configured in 3D Wayfinder Administration panel). Blinking indicates that the item is clickable and you will be guid to it. Clicking will also open a pop-up modal window next to the item. In addition to the introduction text, real pictures are also attach to all items.

Moving Animated Avatars

Additionally, we have discussed adding people to the 3D model as animated avatars. But we don’t plan on adding traditional human figures. Instead, we had in mind to make the avatars moving and differ them by their lilac sorority caps. So that life at the building would seem more lively. By the way, moving people can also be added to our other models, but this is not out of the box solution. If you are interested, please contact our sales manager. Positioning avatars with iBeacons, it would be possible to locate people on the 3D map.

We are happy that such an interesting and different project for us is ready. It is also possible that we are ready to do similar showcase projects again. Projects of this kind would be well suited for exhibitions or museums. We wish the Sorority Amicitia happy 100th anniversary. Vivat, crescat, floreat corporatio Amicitia in aeternum!

In the fast-paced digital era, technology continues to revolutionize the way we interact with our surroundings. One area where innovation has made significant strides is in wayfinding solutions. Gone are the days of paper maps and confusing signage. Today, we explore the synergy between wayfinding with QR codes and NFC tags. How this powerful combination is transforming navigation experiences across various industries?

Wayfinder software has emerged as a game-changer in navigation and location-based services. Leveraging GPS technology, indoor mapping, and intuitive interfaces, these applications simplify the way we navigate complex environments such as airports, malls, hospitals, and campuses. However, to truly elevate the user experience, developers have integrated additional technologies like QR codes and NFC tags.

Many of our customers have used QR codes allready for some time. Because QR-codes provide easy access to building maps without the need for information kiosks. Most people nowadays have smartphones. So with QR-code the map can be open almost with one click. Although with NFC, it is even simpler. Therefore just place your mobile phone near the NFC tag and map will be opened automatically in your cellphone browser.

Now there is option to download QR-codes for each location in 3D Wayfinder administration panel. 

Screens module has to be enable and with each screen there is option to see the QR-code. To download QR-code, you just have to click on it. QR-code will be download in SVG format. It can be used for printing or additional designing.

QR-code takes the template that is mark as default and screen’s location. Screens can be added in 3D Wayfinder editor, by selecting any node and marking it as screen (kiosk). 

QR Codes: Bridging the Physical and Digital Worlds

Quick Response (QR) codes have become ubiquitous in modern society. These two-dimensional barcodes store information that can be quickly scanned by a smartphone camera. Integrating QR codes into wayfinder software enhances the user experience by seamlessly connecting the physical environment with digital information. For instance, in a museum, visitors can scan QR codes next to exhibits to access additional information, audio guides, or interactive content, enriching their overall experience.

We have helped our customers to use QR-code based navigation in parking lots. So that visitors can easily get their car’s location and later on find the way back to their car. Also we have used QR-codes for exploring the corn-maze. Also in smaller shopping malls it is convenient to use printed QR-codes or QR-codes on digital displays without the need for touch-screen kiosks.

NFC Tags: A Touch of Seamless Connectivity

Near Field Communication (NFC) technology enables short-range wireless communication between devices. When integrated with wayfinder software, NFC tags provide a touch-based solution for users to access information effortlessly. Imagine a smart city scenario where commuters can tap their smartphones on NFC tags at bus stops to instantly access real-time bus schedules, route maps, and service updates. See also our solution for showing transportation schedules.

The Power of Integration

The true power of using wayfinding with QR codes and NFC tags lies in their seamless integration. By combining these technologies. Developers create a multifaceted solution that caters to diverse user preferences and accessibility needs. Whether someone prefers scanning QR codes or tapping NFC tags, the experience remains intuitive and user-friendly. With 3D Wayfinder, every code or NFC tag can be configured as different “You are here” location. 

Applications Across Industries

Retail Environments: In large shopping malls, customers can scan QR codes on directories to quickly locate stores. While NFC tags on products provide detailed information and promotions. QR-codes can be use on digital signage screens or printed on walls with NFC-tags.

Healthcare Facilities

Patients and visitors can navigate hospitals efficiently by scanning QR codes on floor maps or tapping NFC tags to access appointment details and medical information. QR-codes and NFC-tags are important part in our Hopsital Wayfinder solution. That is wayfinding application specially designed for hospitals  

Educational Campuses

Universities can deploy QR codes and NFC tags on campus maps. It make easier for students and visitors to find classrooms, offices, and event locations. Students are usually more opened to innovative solutions and they definitely have smartphones with them. 

Transportation Hubs

Airports and train stations can optimize passenger experience by incorporating QR codes on tickets and NFC tags. For example to see real-time updates on departure gates and delays. We have made integrations for scanning boarding passes on airports. So that visitors can be automatically directed to the right gates. 

Smart Cities

Municipalities can enhance public services by implementing QR codes and NFC tags on signage. Because It is important to providing citizens with instant access to information about local events, services, and emergency alerts.

In conclusion as we navigate the ever-evolving landscape of modern technology. Above all the integration of wayfinder software, QR codes and NFC tags marks a significant milestone in improving user experiences across various industries. This dynamic trio not only simplifies navigation but also opens the door to innovative applications that blend the physical and digital worlds seamlessly. The future of wayfinding is here, and it’s more connected and user-centric than ever before. All our long-time and new customers are welcome to implement our new system. Contact us and we will find the best option for you.

We have fixed one bug in 3D Wayfinder that caused transparent meshes to be not visible at all. This
hasn’t accured before. But now it is fix and loading materials for 3D models is also faster now.

In the vast realm of 3D graphics, transparent meshes are a powerful tool that adds depth, complexity and realism to virtual environments. By allowing light to pass through certain areas of a 3D model, transparent meshes offer a myriad of creative possibilities for designers, game developers, and artists and also for 3D Wayfinder users.

Transparent meshes are mostly use for creating windows (glass) in 3D Wayfinder. At the same time transparent meshes are good to mark room ceilings. So ceilings can be click without showing the actual mesh on top of the room.

A transparent mesh, in simple terms, is a three-dimensional object that has some parts or surfaces that are see-through. This see-through effect is achieve by assigning a certain level of transparency to specific polygons or vertices within the mesh. Transparency is commonly represent by an alpha value, where 0 represents complete transparency (invisible) and 1 represents full opacity (completely visible).

Most 3D software packages provide material or shader settings that allow artists to control the transparency of meshes. These settings typically involve adjusting the alpha value or using texture maps to define the transparency level. In 3D Wayfinder we use also shaders for creating mesh-transparency. To use transparency for material, just change the “Shader type” to “Transparent”. The transparency is determine also by the 2 letters in the color (FF is not transparent and 00 is fully transparent).

According to one of our last projects. We found out that not all transparent meshes are shown.

This bug was fixed by overwriting the code for loading materials. So the bug has been fix and loading
process for materials should be also faster.

Please read 3D Wayfinder tutorial about managing materials and transparency settings. We also have some guidelines for creating 3D maps (https://3dwayfinder.com/documentation/docs-floor-plan/modelling-guidelines/) for 3D Wayfinder, please look them also before starting to create your own 3D wayfinding maps.

We are currently developing voice recognition feature for 3D Wayfinder. It will allow visitors to use wayfinding software without using touch-screens. Just say where you would like to go and wayfinder software will show you the way.

Voice recognition is becoming more popular and as the quality recognizing words is becoming better and mobile screens becoming smaller. It would be convenient to use voice orders instead of using touch-screens. Of course, there are privacy issues, as most of the voice recognition is done in servers. But for wayfinding software this is not an issue, as the wayfinding screens are public and nobody will make their private conversations near wayfinding screens.

How voice recognition for wayfinding works?

Let’s say you are looking for closest exit, toilet or just want to get a beer. So you just say “Exit”, “Closest toilet” or “Wayfinder, where can I get beer” and 3D Wayfinder can show you the route.

3D Wayfinder will use keywords and location names for voice recognition, the same way search functionality works. More keywords defined in wayfinder make the vocabulary larger. But definitely there will be AI implement in future. This will give much more possibilities. For example visitors canaska pint of Budweiser without “Budweiser” being entered as a keyword and still get to place where they can buy beer. Might be that the beer is not sold by pint. But at least they can get beer.

We can use languages for voice recognition, that are select in Wayfinder software. Languages can be add under settings in 3D Wayfinder administration panel. If possible, voice recognition can be active for all languages simultaniously. If not, we can use default language for voice recognition without selecting anything. After selecting prefered language wayfinder can switch also language for voice recognition. This depends capabilities of kiosk or touch-screen PC. Also, the challenge is to filter out background noise as wayfinder screens are usually in main entries and places where are more people around.

In future, voice recognition in wayfinding software will be available for all customers. It has to be turn on under settings and it would also require template that allows voice search. We will add this feature to our basic templates. So far, we can implement it in custom templates. So if you order custom template from us, we can also make search by voice available.

WE are adding augmented reality (AR) and mixed reality features for 3D Wayfinder. With AR and mixed reality it is possible to provide map information and directions on camera image. This makes wayfinding in large buildings even more simpler and extends the possibilities to use 3D Wayfinder.

3D Wayfinder provides interactive 3D applications and real-time rendering solutions in self-service kiosks, mobile applications, maps on websites and indoor/outdoor positioning with Bluetooth iBeacons or GPS. We have worked with organizations across the globe. We have developed our own WebGL engine-Frak. It is open-source and free.

With WebGL becoming a standard in web browsers and by improving the speed of Frak. We have widened the purpose of 3D Wayfinder to be used for example for architectural visualization, property management, BIM software etc. Thanks to a powerful API and open architecture, it is possible to use 3D Wayfinder in other areas and applications.

Currently we are hiring AR developers. Doesn’t matter where you are located. You can be the proud member of our team. And at the same time work from your home. It doesn’t matter to us where and what time you work. What matters is the result. We have a thrifty team and we communicate with each other online on a daily basis. We offer support to all our employees. For us there are no stupid questions or silly ideas.

We welcome you to our team if you have the necessary skills in developing augmented reality or you are very interested in this and capable to learn fast. Bold initiative and the ability to work in a team are a bonus. If you recognized yourself, write to us and we’ll talk about everything in more detail.

Required skills are:
– web-programming. This means Javascript, HTML, CSS etc.
– It would be good, if the candidate has experience with AR development: how to get mobile device direction, use gyroscope, render content on camera image.
– It would be good to have some experience also with WebGL.

Come to our team and help to develope AR for 3D Wayfinder.

The world biggest cruise ship “Wonder Of The Seas” has more than 2800 rooms and accommodates more than 6900 people. Wonder of the Seas measures 1,188 feet (362 m) in length and has a gross tonnage of 236,857 across all 18 decks. Since all rooms and activities are compactly together on cruise ships, it is necessary for people to have all the information on important activities and locations. Indoor positioning on cruise ships is an important comfort for the passengers. We present to you the indoor positioning solution for a cruise ship created by 3D Wayfinder.

So far 3D Wayfinder has been used with a simple 2D map for small cruise ship. The ship has a total of 17 floors and around 1000 rooms. Below you see excerpts from five different floors.

Cruise ships have many different leisure options. As you could see on the photo, there are pools, saunas, a theatre, different shops, kids playground and many more. If you are going to be spending time on a cruise ship, it is very important to know where the different rooms and areas are from the very beginning.

Using GPS on metal vessels is difficult. Indoor positioning on cruise ships can be organized using iBeacons, WIFI or QR code that can be opened through a web browser. 3D Wayfinder has used all the proposed solutions and we know exactly how to build the system in a way that would be the most suitable for the customer.

Digital maps on cruise ships

On large ships there is a high risk of getting lost. Therefore, it is important to have interactive maps in various places on the ship. 3D Wayfinder map shows the route to the desired location with a red line. In comparison to regular printed maps, digital maps significantly reduce the time it takes to search for a location. On regular maps, it is very difficult to determine your location and then understand where you want to go.

Easily updated information boards in the elevators

In addition to the possibility of finding the location, 3D Wayfinder also offers information boards that can be installed in the elevator. Information about events on the cruise ship can be added to the screens. You can also share information about meal times and the use of other important services, which is necessary for all visitors. In addition, it is very easy for employees to exchange information on the screens.

Digital maps on a cruise ships as billboards

Most people do a lot of shopping on cruise ships as cruise ships often have better prices than regular shopping centers. In order for different shops to advertise their goods, it is possible to add advertisements to the map. This can be a good way to attract people to the store. In addition to shops, services like spa could also be advertised in a kiosk. For example, additional information could be added to the location and people could view the spa services and price list without them having to go to the spa in person.

In the world of entertainment, it is important to stand out and offer customers all the comforts possible. And one of the great conveniences for visitors is certainly a practical navigation service. If you are interested in the services offered by 3D Wayfinder, please contact our sales department.

ISE 2023 Expo is probably most important technology expo in Europe. This year it was biggest yet. ISE 2023 attracted 58,107 unique attendees from 155 countries, making 133,606 visits to the show floor. Especially busy was Multi-Technology hall. There we had most fun meeting companies too. Special thanks goes to for citizens of Barcelona. Even with limited English they left to us superb expression. We were pleased that the event was in city where people are kind and helpful for the first time visitors.

ISE 2023 Expo organization

ISE 2023 Expo experience is that was really well organized Expo. There were large halls and easy to access booths. The catering was also very well organized and managed. We saw some very unique solutions. Especially interesting was 4K LED screens with IR touch. Making it suitable to use in interactive digital signage and 2D or 3D wayfinding solutions.

In two days we when we visited expo, we got a lot of positive feedback for our software. Companies were most interested in our 3D maps that we have built for indoor navigation. Some of the companies we visited needs to be highlight also in our blog.

Nice meetings at the event

With representatives of Cisco we quickly found a common topic of conversation. We talked about smart rooms and today’s business environment. We understood in that moment how right our direction has been for years. Also especially happy to see that we have yet to offer more opportunities then international corporations like Cisco can do. This motivates us to keep working hard.

Highly interested meeting we had was with BrightSign. Their digital signage players were interesting that can be potentially used for our software. We talked about to give better hardware tools for our clients. Especially interested us plug and play solution. Also it may be solution for our clients, who have little experience with digital signage and players for interactive screens. If everything goes well then we will have also hardware for our clients that is reliable with good price range.

We also visited booths of Clebex and Telelogos. Both are big IT companies and with very interesting field. They are definitely worth to explore. We started of right a way with productive talks and of course our topic was about potential of 3D Wayfinding. 3D Wayfinder software gives additional tools build powerful business solutions for end-clients!

Interactive displays manufactures at ISE

We got new and interesting knowledge in Chinese display manufacturer HCTek. Interactive displays is what future holds. HCTec is large interactive display manufacturer providing OEM, ODM and OTM solutions. Many well known display brands get their interactive displays from that factory. For us it was important to know what future brings. Talking was very productive and we had good laughs and took picture!

Then we met LED manufacturer AOTO. In our talks we covered many aspects of today digital signage market directions. Also we both agreed that future will be LED. Especially in indoor and outdoor digital signage field. We were also invited to their 30th anniversary celebrations to Happy Hour.

Our sales director Rainer Saar shared his experiences.
