Selleo has been an outstanding partner. They've worked alongside us on several projects, and their team consistently feels like a natural extension of our own - collaborative, engaged, and fully invested in the outcomes.What stands out most is the quality of their people. They bring professionalism and technical excellence to everything they deliver, hitting deadlines without compromising on standards. In a space where reliable execution matters as much as raw talent, Selleo consistently delivers both.We wouldn't hesitate to recommend them to anyone looking to scale their software engineering and research capability with a partner who truly embeds in your team and treats your goals as their own.

Selleo helped us scale from $0,5m to $40m and has been an excellent development partner for us in every way. I highly recommend Selleo for all software development projects. "Kristoffer Persson's Review Sourced from Google
I have partnered with Selleo for several months of development. I have been extremely pleased with the team, their work, involvement and ideas. I would definitely recommend them again to my network. "Romain Joly's Review Sourced from Google
We hired Selleo to do a redesign of our app. Poor communication, repeated missed timelines and a very poor quality of the small items that were delivered. Anna (Head of Business Development) ironically kept asking us if the "project was on track" and if we were "happy" with the project and despite our negative feedback did nothing to get the project back on track. We eventually fired Selleo after wasting $20k on this project. I would not recommend using Selleo. "Project Name: Redesign Widget
