Existek’s blockchain experience proved to be quite useful. They contributed to the general system architecture, showing us how something could be done better or faster. After a few weeks, we didn't feel like we were working with external developers. It felt like we had an in-house team working with us in the same office. Existek's top-notch deliverables, reliability, and seamless collaboration made them a valuable partner, while their niche expertise contributed to a superior product.

Existek is one of the rare providers that can transform a pure idea that started on a napkin into a custom software that meets all needs. Their reach technical and business expertise allowed them to come up with suggestions that added significant value to the final results. The project was completed on the tight schedule and without exceeding the budget. I would definitely recommend Existek as a reliable adviser and executor for all your software initiatives.
