Christian Rohner

Project Manager at Information Products AG

“Quality of delivered work is outstanding”
Our company worked more than 5 years in total with NIX. Communication was always very clear and direct. Being a remote company, wasting time in communication is horrible, luckily with NIX, we experienced no delay or misunderstanding. Quality of delivered work is outstanding, all tasks prior to delivery were tested in detail, and bugs or mistakes were virtually non-existent.

Eric Spear

SVP of Engineering at Cengage

“Delivering high-quality code”
With NIX, I have broken some of my own rules of team composition with respect to the ratio of FTE and 3rd party engineers. I have some teams that are more than 50% NIX because the code coverage, quality, and velocity coming out from the NIX developers are very good. Delivering high quality code in a predictable manner has built trust and confidence with my management/full-time employees.

Ilya Kottel

VP R&D at HumanEyes

“You have done the work perfectly”
I want to say thank you for the excellent, highly professional work, for your passion, and your time even on holidays and weekends. Your attitude ultimately led to outstanding results. We are satisfied with the result we’ve achieved, but we need to keep working, and actively use every opportunity to make it better. You have done the work perfectly and the application, which you created in such a short time, turned out to be very functional and cool.
