We build the dial
we wished we had.

Rheostat started in 2022 after one of us rolled back the same release four times in a night. Today 1,900 teams use it to ship without the fear.

Four years, one idea.

2022

Two founders, one flag server and a very bad night.

2023

Open-sourced the core. 1,000 stars in a week.

2024

Auto-rollback rules and the first enterprise customer.

2025

Agent traces, judges and approval gates.

2026

1,900 teams. 3.1 billion evaluations a day.

A change you can undo in a second is a change you can make on a Friday.

Opinions are welcome. Data ends the meeting.

Every action we build needs a way back. No exceptions.

Decisions live in docs, not in someone’s head.

64 people in 19 countries. We meet in person twice a year.
