Every product here has a face.
Teachers who spend their Sundays on worksheets. People who let apartments, and people who build whole houses. A winery fed up with its ERP. We’re a handful of master’s students. We listened, then we started building.

Pinoterra
It started with: a winery that couldn’t stand its ERP any longer.

Who we are
We’re a handful of master’s students with a startup. We don’t build for markets that look good in an analysis. We build for problems someone told us about at the kitchen table. That’s why the first users of every product are never more than a phone call away, and when something breaks, we hear about it the same evening.
And we’re far from done.
