The people who ship

A small senior team, with no layers in between. The people who make the decisions are the same people who write the code and put it live — and stay on to run it after launch.

There is no account manager here. The person who plans your project is the person who builds it.

Since 2018 · Istanbul · Amsterdam · Miami

The person you message when something breaks at nine on a Friday is the same one who built it. That is the whole reason to stay this size.

Design and engineering sit in one team, so what gets designed is what gets built — nothing changes when the design is passed on. We have been doing this since 2018, with 15+ years of WordPress behind the team, and much of what we built in that time is still running under our care.

Everyone here also writes: the technical posts on the blog are written by the people doing the work, not by a content agency. If you want to know how we think before you talk to us, that is the honest place to look.
