Royal Navy

Nathalie Zwagerman, Communications consultant Social Media

"DTT contributed to a hassle-free experience for our visitors during the Marine Days by developing the Marinedagen app.

A fantastic result was achieved in a relatively short period of time. Among other things, the app enabled visitors to keep up to date with the latest news, follow the programme and discover the grounds via a clear map. The application ensured that our visitors were properly informed before, during and after the Navy Days.

We have come to know DTT as a reliable partner who thinks along in solutions despite the necessary challenges. They are available for questions 24/7. All in all, a very pleasant collaboration. Thank you for that!"

Universiteit Twente

Kamer van Koophandel

Marco van Hagen, business support consultant and Gabriëlle Hoogendoorn, productmanager

"Very recognizable, the description from other organizations about the cooperation with the DTT team.

DTT pleasantly supported our team in developing game concept into a fun and educational app that allows entrepreneurs to learn more about importing through play. By playing import missions, users receive immediate feedback on their own knowledge level. Through the achieved score and ranking, they challenge friends to compete.

DTT worked out a complete game in a short lead time. Short lines of communication. Clear in expectations management. Great patience with our search for the maximum achievable within the proposition. Good at translating wishes and requirements into a practical solution."

Ministry of Health, Welfare and Sport

Marlies P. Schijven, CMIO Ministry of Health, Welfare and Sport

''DTT has built the 'ziekenhuisbedchecker' for the ministry of Health, Welfare and Sport, with which we can give every healthcare provider free insight into the available beds, IC and non-IC, COVID-19 and non-COVID-19 in the Netherlands from existing registration systems. The ziekenhuisbedchecker has recently been expanded, so that the availability at the emergency department is now also visible.

This is going to help us enormously even after the corona crisis. After all, ambulance services know whether they should drive to a hospital or not, and GPs can see if there is a bed available at the emergency room before they have to make rounds if they want to send in a patient. DTT has really done this in record time, I am very impressed by the commitment and thinking along in turbulent times. Very professional, well-coordinated party. Definitely the right choice!''

Randstad

Joost Schriever, Global Director Marketing

‘’DTT has built an application for us, with which we can digitally replicate and decorate every Randstad location in the world. This will help us tremendously during the worldwide spread of our new positioning Human Forward. Furniture, wall decorations, floors and other elements can be placed into the location with the tool. Simultaneously, a calculation is being made of the coinciding investment.

We have gotten to know DTT as very professional, creative, correct and extraordinarily fun.’’

Greenpeace Nederland

Ehtimaad Rais, Online Campagner

"Speaking for both myself, Joost and the entire projecteam, I would like to thank DTT deeply for your efforts. We are thrilled with the end result!

When we approached you with the request to make penguins appear everywhere in the Netherlands through AR, we received an exceptional proposal. A very entertaining elaboration of our campaign to make the South Pole a protected marine reserve. Together we quickly came up with the name for the King Penguin app and fun occasions to use the app so everyone can search virtual penguins via AR in their own neighborhood. By combining this quest with information about the animals and their threatened environment at the South Pole, awareness is created in a playful way. And that's exactly what we wanted. Once again, compliments on how fast you brought this amazing app into the digital world. I experienced it as a very pleasant collaboration."

Laborie

Albert Meek, director R&D

''Laborie specializes in the development of medical equipment. Some of our older medical equipment (urodynamic system) uses an Android board for a user interface (touchscreen display). DTT helped us perform an essential update of an embedded Android app on our urodynamic devices. The changes were related to the communication between the system modules and the Laborie PC software that connects via Bluetooth. Recent problems with component availability caused a shortage of Bluetooth chips, so we had to modify the Android interface to work with a USB connection.

Using their knowledge and expertise, DTT adapted our Android app to communicate with our peripherals via USB or Bluetooth in a timely manner. The development and communication with DTT went very well and we are grateful for their support in making the necessary adjustments to our Android application. DTT has proven to be a reliable partner that helped solve our problems. We enjoyed the collaboration and will work with DTT for future Android projects.''

I-Sec Netherlands

Camiel Kuiper, projectmanager

''With the progressive web app developed by DTT, we have a reliable medium through which our colleagues have 24/7 access to various HR matters such as the schedule, but also (news) messages.

With DTT's expertise, we developed and implemented the PWA entirely on schedule. The development process and communication went smoothly, with DTT thinking along with us. Now more than a year later it is still running smoothly.''

Municipality Hollands Kroon

Han van Egmond, core administrator

''Litter is a major annoyance for a lot of people.'' At the elementary school of the municipality of Hollands Kroon, children from group 6 had the solution. A game-app should contribute to the reduction of litter.

We came to DTT with a reasonably well-developed idea. The idea was received with great enthusiasm. The game is intended to make young people aware of the litter problem.

DTT pleasantly surprised us with the development of this app, Operatie Z.U.I.V.E.R. The game, like Pokémon GO, can be played with Augmented Reality in the public space. The game is instructive, you can play alone, but also with groups against each other. In the app you can add schools and sports clubs to compete with each other. We think it can make a major contribution to the awareness of litter among the youth. DTT has helped us enormously with the development of the app. They think along creatively, come up with solutions and are ready to answer our questions. Together we have expressed our intention to develop the app further.''

Dutch Media Literacy Network

Aniek Breevoort, Productmanager

''Since the beginning of 2021, Dutch Media Literacy Network has entered a collaboration with DTT for the serious game MediaMasters. In a very short time (6 months), DTT has developed a completely new version of MediaMasters including a teacher portal, Content Management System (CMS), website and the game environment itself. They have done this very skilfully with an eye for detail and planning. DTT is an agency that can think along with you about what is necessary, acts adequately and is very reliable. They also offer good service on the solution and have a high response speed if assistance is needed. We are therefore very satisfied with this collaboration.''

Real-Time Road Inspection

Andries Takke, director Takke Breukelen B.V.

''A safer Dutch road network, that's what I longed for about eight years ago when the first idea for Real-Time Road Inspection (RTRI) popped into my head. For my work at Takke-Breukelen B.V. we are on the road a lot. While driving, you see many deviations in the infrastructure, such as holes in the road or traffic signs that are placed incorrectly. Surely there should be a simple way for this information to reach companies who can do something with it?

Once the idea was born, DTT was able to convert it into the RTRI app, which delivers real-time images of the current state of roads and public spaces and sends them to an online platform that companies can join. A useful app for any company that has anything to do with public space. This is because it allows for the quick resolution of infrastructure anomalies. Users also have the option of flagging images when deviations are noticed on the road, for example when there is damage to the road surface.

We at RTRI are extremely satisfied with the app developed by DTT. Everything has been thought of. Faces and license plates that are loaded into the app, for instance, are blurred by means of Artificial Intelligence. In this way the privacy of everyone is guaranteed, while the app can do its work. DTT has also ensured that new data automatically replaces outdated data. Moreover, a very complex caching mechanism was used, because a lot of data will be loaded into the app (over time). A fine piece of work, in which we have experienced a very pleasant cooperation.''

Harjo Keizer, advisor care innovation and ICT

“We have come to know DTT as a great club to work with, a proactive attitude and thinking along with the client are of paramount importance. At the start of the collaboration, we deepened strategy and concept with DTT, followed by the delivery of a creative strong design with strong gamification elements. Furthermore, their organizational strength and process-oriented approach ensured that we moved smoothly and steadily towards a nice final delivery.”

The Netherlands Nutritions Centre

Irma Evenhuis, Project Coordinator

"The Canteen Scan, an online tool that helps providers to make their eating and drinking facilities healthier, was ready for an update. We have put a 'dream scan' on paper with all our wishes and those of our users. Together with DTT, we translated it into a design, which was then built.

With multiple user roles, different needs per environment where food and drinks are available (school, sports, work) and the link with an existing food database, the Canteen Scan is not a simple tool. But DTT has succeeded in translating our wishes into a nice tool. The new Canteen Scan is a visually modern, adopted and user-friendly web app.

Those involved in canteens and restaurants can enter the products offered and their placement on the basis of photos. Users additionally receive advice for improvement, so that locations are able to take steps towards a healthier eating environment that stimulates consumers to make healthier choices."

Dutch Noorderkwartier Water Board

Marieke Duijn, Communication advisor

"We wanted to develop an online game that would make people more familiar with the work of the water board and what residents can do themselves for clean surface water. With facts about water so that it is not only fun, but you can also learn something while you’re playing the game. DTT has helped us a lot in the search for what eventually became the HHNK Clean Water game. A fun competitive and informative game. The creative and approachable employees of DTT and their quick actions during the development process have positively surprised us!"

Multibel

Maurits Knopjes, co-director Multibel

“The DTT design team has helped us a lot to update the website, to get more conversions and to improve it technically. The same with our MultiBel app. The challenge was the combination of a modern design with improved user-friendliness. We are very satisfied with the result and this certainly makes you want more. Dealing with the team was pleasant, from the big boss to the individual designers, all professionals. SEE YOU SOON.''

SportWallet

Pieter Rüpp, Co-founder SportWallet and Maurits Rüpp, Co-founder SportWallet

“With an idea in our heads we ended up at DTT. The initial communication went smooth and before we knew it, we had a meeting at their office. After a few brainstorming sessions we immediately went into the design and development phase and the results speak for themselves! It's extraordinary how DTT’s team managed to convert the idea in our heads into an actual app. Thanks to the experience and expertise of DTT are we able to control and manage the CMS of the app very easily and in an efficient way. Our decision to collaborate DTT has been the correct one and I would recommend them to everyone.”

KPMG

Patrick Özer, Senior Manager Forensic Technology

"DTT has helped us twice. First, DTT devised a prototype for an app and when this was well received, they made a fully dynamic version of the app. Our needs and requirements were not easy to fulfill, but during the pleasant co-operation we have come to a good design that satisfied both parties. In the implementation phase DTT came up with good proposals for the app, but also gave us good advice on how we could position our app within the organization. It is amazing how our complex scoring model was so easily implemented, so our non-technical colleagues can manage this through the back end."

Erasmus MC

Mary Dankbaar, Program manager E-Learning

"We wanted to create an additional training environment for medical students. On the basis of realistic medical cases, they can learn how to interpret heart and lung sounds. In collaboration with DTT we have developed Clinical Challenge app, so students can easily practice their knowledge.

DTT was a reliable partner; employees think along with you, quickly answer questions and provide quality results. Through a good rating system with highscores and attractive animations with sounds, it resulted in a good app. Students are excited about e-learning and are more eager to learn."

Bouwend Nederland

Ad van Luijt, chairman of the Build@School Foundation

"Since 2015 we are playing a construction game at schools to encourage students to choose for construction technology. This game in which a Lego house has to be built, was supervised by a few game leaders. As it was becoming a problem to find enough game leaders every time, the decision was made to change the game into a digital construction game.

This is how I came in contact with DTT in Amsterdam. After meeting with Jeffrey and his organization, we decided to let DTT build the game.

This has been done to great satisfaction of our Foundation "Build@School". The employees of DTT were always there to process questions and suggestions that we had. The game is being played for a year now and we intend to expand the game further. Of course we would like to do this again with the cooperation of DTT."

De Lotto

Fiona Mirrer, Coordinator Marketing Communication

"For our most popular and best-known lottery scratch-card, December Calendar, we came up with the idea to develop a fun game that you can be played both on PC and on your phone. For this, we started looking for a multimedia partner and found DTT. Despite the short timetable, DTT delivered a super game: the December Calendar game. This game, starring the penguins from the December Calendar 2014 lottery scratchcards, is based on an existing game and is intended as a free fun bonus. You can't win (money) prizes, but you can get the highest score! Communication was smooth, clear and fast and we could always turn to DTT if we had questions. DTT also thought actively us on how we could generate more downloads and gave us good advice where necessary. In short, DTT has been an excellent partner. We will certainly continue working with DTT in future."

RIVM

Desirée Beaujean, Head of Development and Implementation Department

"The RIVM (National Institute for Public Health and Environment) had the "Tick bite" app launched in April 2014. This app was initially developed for Android. With this app people can check what ticks are and how to correctly remove them (even without internet connection!). Starting from July 2014 the app will be available for iOS also.

In the beginning we have spoken with a number of potential executors and we chose for DTT. What struck us was that from the very start DTT was very involved in the issue and the development of the app. The rates were reasonable and certainly played a role in choosing DTT. During our collaboration, we got to know Jeffrey and Dirk better. We emailed and called each other so often, we even noticed the urge to contact them when it wasn't even necessary. I think that says enough!

In short, DTT has been a great partner to develop an app. They are reliable and always up for a joke. Great job!"

"DTT has really done a great job by developing the first KNHS Dressage and riding tests app for iOS and Android. Despite the short development time (and thus high pressure on the project) DTT has taken the usability of the app into account and has given clear advice on functionality and design. Thanks to the pleasant and efficient co-operation, the app could be launched on schedule and within budget. This was well noticed: the app reached the number 1 position in the category 'best paid' in iTunes. The team of DTT is commited, enthusiastic, works fast and communicates clearly. An absolute must!"

"We were looking for a specialist, that could guarantee speed, transparency and quality of service and product and think along with the client! DTT has managed well to deliver the first project, a sales app for our international branches.

We decided to give our second project, a web portal for our international customers, to DTT as well. I am curious whether DTT will manage to succeed here. After all, as they say "You're only as good as your last game", so you have to prove yourself over and over again!

Project 3 (a second Sales app) and project 4 (a complete new website) are still on the drawing board, so .......!? "

In short, DTT has been an excellent partner, and we will continue to co-operate with DTT for the further development of the app especially."

Saint Gobain Glassolutions

Jeroen Thuis, Marketing Manager

Glass Solutions was looking for a flexible company that could quickly develop an app. We've sent out our assignment and DTT reacted accurately and fast. Also during the fulfilment of the assignment they maintained a great service level. The realization of the app on Android and IOS, both phone and tablet is completely provided by DTT. Co-operation with the DTT team was excellent, with adequate and clear communication. Glass Solutions is a satisfied customer.

Intermac BV

Bart Willemse, Owner

We approached DTT for the development of an internal iPhone app, we knew exactly what we wanted and what the challenges were. Several other app developers promised that they could deliver this app as well, but DTT was the only company that showcased that they could develop this application with the help of a video. This gave us the proof that we we’re talking to the right company, and that is proven! Quick and correct responses to our questions and no fuss with minor changes. In short, we will certainly use their services more often.

MobiGreen, Vanenburg Group BV

Henk de Vreugd, General Manager

"For the development of our MobiGreen mobile application we have chosen the services of DTT. In hindsight, the right choice. Our experience with DTT is:

Quick feedback
Comprehensive answers
Good technical expertise
Reliable partnership with modern approach
Proper price/ performance ratio

Hopefully we will have many years of pleasant co-operation."

4Sight

Mark Berntssen, Sales and Marketing Manager

4Sight develops Virtual Reality for the urban planning industry. Thus we support and advise governments and developers in marketing their plans. With visualizations you can create more understanding, trust and support for the property development and infrastructure projects. We have asked DTT to extend our pallet of visualization products by an iPad application for infrastructure projects. Besides the very pleasant and open collaboration, DTT offers a quality product, with fast delivery terms at a very competitive rate. Multiple suppliers are able to deliver quality, but next to that, commitment and customer orientation in favor of the client is a second nature for DTT!

MILK Strategy & Finance

Laurens Oosting, Consultant MILK Strategy & Finance

MILK Strategy & Finance is one of the most prominent strategic and financial consulting companies for small and mid-market. Our services include: Financial Management, Mergers & Acquisitions and Strategic Management. We have worked with DTT on the development of a new strategy to advance the website of one of our customers. The speed and service provided by DTT makes them a pleasant business partner to work with.

Minicards

Arnold Gruppen, Owner

We decided to build a Mobile application to provide our advertisers with an extra platform and to react on the current consumer demand. For this project we approached DTT. We are very satisfied with the short delivery time that was needed to finish the application. The level of communication was above expectations as well. In fact, they chased us more, than we needed to chase them to finish this project :) The result is very pleasing. Next to that, the after sales service was just great.
