Our Story

Two developers left corporate in 2017 because they believed software gets better when clients talk directly to the people building it. No layers, no translators. That's still how we work - a remote team of 25, where developers lead projects and own client relationships. Eight years later, the longest client relationship we have is still running.

What Sets Us Apart

No middlemen

There are no project managers sitting between you and the team. The developer on your project handles communication, owns the timeline, and is your main point of contact throughout.

A team that sticks around

26 of our projects have run for 2 or more years. Clients don't tend to leave because the people they're working with feel like an extension of their own team, not a rotating roster of contractors.

We advise, we don't just build

Every developer is expected to understand your business goals, not just the technical brief. That means you get someone who'll question the approach, flag a better path, and think about what actually moves your business - not just close the ticket.

Premier Verified means Clutch independently confirmed THEY.dev is a legally registered business,
financially sound (Creditsafe: Very Low Risk), and backed by 28 verified client reviews averaging 5.0 stars.
