It Takes One to Know One

Companies We’ve Built

Kin and DoneDone started as needs we had as a small company trying to compete in the very dog-eat-dog world of software. We decided to build both products into fully-fledged businesses because we knew that, if they helped us, there were a lot of other organizations that could put them to good use too.

They’ve improved our workplaces, those of thousands of other organizations, and they’ve shaped the way we help our clients too.
