What founders say about us
Real feedback from those we've helped succeed.
"I was a bit apprehensive about paying upfront for a discovery session, but it was money well spent and in safe hands."
Roger Möllerström
Founder, Dynamic Events AS
"He is deliberate in his tactics, thoughtful in his communication, and swift in his execution. On top of that, Guillermo is just enjoyable to work with, providing a contagious energy to every project he touches."
Michael Ashley
Founder, The Ashley Group
"Guillermo and his team worked on my project creating the mobile app NiteOwl, using React Native with TypeScript. His code quality, diligence and communication are exceptional. I want him to join my team in Austin, TX full-time - that’s how just good he is."
Avery Pawelek
Founder, ACP Software Solutions
"Along the process, we felt cared for, as if they were part of our business, and not an external contractor doing a transaction."
Ravn Wiik Steinsvåg
Co-Founder, Hawii Analyse AS

Agustin Ruiz Miller
Founder, Pinch Kit
"OH MY GOODNESS!!!!! This is amazing!!! Chanda and I opened it up and looked at it together and we were "WOWed!" This is what we've been looking for. I love the different ways you can search, and the ease of functionality. I know we need to spend some time digging a little deeper into it, but we are amazed and so excited for this. You (and anyone else who's been working on it) have done an outstanding job!"
