What founders say.
Rated 5.0 on Trustpilot and G2.
“We started with one product and a twelve-person team from zoof04. A written plan every week, a demo every Friday, and nothing hidden in the budget. When our older product needed a new home, we moved that to them as well.”
“Two hundred thousand registered users on an app built and run by a team of ten. Live classes, subscriptions, AI features, all shipped on the dates they put in writing.”
“I'm not technical. I got a fixed price before we started, a plan I could actually read, and progress I could see every single day. That's why I signed.”
“Twenty engineers for more than four years. They became our engineering department, on our tools, in our standups, to our standards.”
“Three and a half years as our primary development partner. Eight engineers across a device fleet, a multi-tenant metering dashboard and billing, and they never missed a release window.”
Teams we've run, and for how long.
Dedicated teams of one to twenty engineers, inside the client's tools, for as long as the work needs.
