what clients say about us?

The code and the work were good quality and really what we were looking for. They were able to bring technical design thinking to the project. Project management was tight and I always knew what was happening.

Daniel Kiyoi

CEO & Founder Magic Dust

Apptension was flexible and professional. When I needed to quickly add capacity, it took a week or two at worst - often days. The cooperation enabled me to slowly scale up my own IT team, and the company was very helpful until the last moments of the transition.

Mateusz Oleksiuk

CEO LESS_

The technical creativity delivered by the team at Apptension was invaluable in the formation of our mixed reality start-up Hyper.

Nathan Sparshott

Co-Founder & CEO of Hyper

The SaaS Boilerplate Apptension built was a huge reason we were so successful, because all these little seemingly unrelated tasks and integrations needed to happen. If we had been working with anybody else, It would have probably taken months to do the same work.

Kwame Nyanning

CEO blkbx.

We needed their help to build the backend services and capabilities needed to deliver a production level on demand. Their ability to produce high-quality work with consistency while dealing with a new type of project was impressive.

Kelly O’Conor

Product Lead, Siberia

The project’s success has resulted in a long-term partnership for design and development. Apptension is a fantastic partner, who is willing to go above and beyond in order to deliver what the client needs.

Catarina Rocha

p(r)oud solutions

Apptension fared well in our project, working with our bespoke CMS and complex requirements. The designs were implemented well and the schedule was kept tight.
