What we do

Most of our work is long-term. We join a team, build the hard parts and stay to keep them running.

Backends, web apps and integrations, built to be maintained by your team after we hand them over.

Language models connected to your own data and workflows, with the checks that make them safe to put in front of customers.

An outside view before a big decision: architecture, vendors, security or a system that is getting hard to change.

The same four steps whether it lasts a month or a year.

Step 1
Talk
A call about the problem, the deadline and what already exists.
Step 2
Scope
A written plan with what we will build, how long it takes and what it costs.
Step 3
Build
Short cycles, working software every week and access to everything we write.
Step 4
Run
We hand it over with documentation, or keep running it for you.

We also build and sell our own software. It keeps us honest about what it takes to run a product every day.
