Some of Our Happy Clients

  • Andreas Karantzas Andreas Karantzas Head of Software at Kinastic Coach The well-structured workshop with EL Passion’s team gave us a valuable in-depth roadmap that we followed all the way through our app’s MVP launch. The professionalism and the critical-thinking mentality that the EL Passion’s team brought to the table, helped us visualise our priorities and goals in a manner that was easier to follow development-wise.
  • Andrzej Wróbel Andrzej Wróbel CFO at Mednavi case study They are creative when approaching challenges, and the results they deliver are impressive in terms of quality and time. EL Passion helped us with design and development, but they also gave our product vision a clear shape and form during a Product Design Workshop.
  • Andreas Gallefoss Andreas Gallefoss Product Manager at Varner case study EL Passion enabled us to achieve our business goals with their solution. Thanks to the AI based engine they developed together with the Norwegian data science consultancy deepinsight, we managed to grew our sale on old products with more than 16% (>4.5M EUR) during one seasonal sale alone. The solution will continue to have a huge impact on Varner’s long term margins. They are knowledgeable experts willing to take ownership of the project, and they delivered a quality solution ready for implementation.
  • James Tjan James Tjan Product Manager at Polaroid case study For us working with EL Passion means to have a committed partner who is constantly proving to deliver a great mobile experience for the global market. We have a very open and honest working relationship, with trust, respect, commitment and fun being the core ingredients. We try to operate as one team and not as vendor/client. To me their focus on motivated and passionate people adds the human element too often missing in the tech industry.
  • Nikolai Fasting Nikolai Fasting CTO at Pioner Labs case study We have entrusted EL Passion with building one of the most business critical components in our latest massive e-commerce projects developed with Varner. And I’m happy to say that it proved to be the right choice; smooth communication, professional team management and good engineering helped making the solution rock solid and enterprise grade. We will definitely work more together in the future.
  • Konrad Howard Konrad Howard CPO at Booksy EL Passion’s work resulted in higher conversion rates and improved user experience. They mastered project management, so we were able to be informed on every step of the project. We were impressed with their skills and outstanding designs and code they delivered.
  • Solvor Øverlien Magi Solvor Øverlien Magi CEO and Founder at Lifeness After a failed attempt to build an iOS and Android app with another vendor, we engaged EL Passion to build the project for us. After the kick-off meeting, they quickly found out what we were aiming for and delivered what we wanted in time. The team's success has been responsiveness, flexibility, ability to listen and understand the problem and willingness to find the best solution. EL Passion is professional and adaptable and meets customer goals through close dialogue and smooth workflow.
  • JULIE LEPIQUE JULIE LEPIQUE CEO at femtasy case study I recommend EL Passion because of their agile way of working and focus on achieving top-notch quality of the product.

  • Arnaud Grunwald Arnaud Grunwald Founder at Hyphen, now Chief Strategy Officer at Betterworks EL Passion’s mindful UX decisions and UI design skills helped us simplify the overall Hyphen experience.

  • GABOR WNUK GABOR WNUK Mobile Tech Lead at WP case study The team workflow is phenomenal. Thanks to the continual communication and partnership relations with the team we were able to avoid a situation in which it would be necessary to prepare thousands of pages of documentation. We were able to focus on the product rather than the paperwork.
  • MATEUSZ MIKULSKI MATEUSZ MIKULSKI Head of Mobile Development at Docplanner case study It's great that EL Passion takes care of the quality of the code as well as the product.
