About rethinker
We think Claude coding agents can take on real engineering work, including the unglamorous kind: long sessions in large codebases, and modernizing systems nobody wants to touch. rethinker builds the tools that make that practical.
The team
A small team of engineers who use coding agents on real codebases every week. rethinker started from our own long sessions, and we use it on our own work.
Product and direction
Sets what we build and why, and keeps the product honest about the cost it actually saves.
The product
Build the Claude Code companion today and the legacy modernization workflow next.
Beta teams
Works with our private beta teams and with new teams who want to try rethinker.
Where we are
Our first product, focused Claude Code sessions, is in private beta with external teams. Legacy modernization is in development. We are based in Türkiye and work with teams anywhere.
