Northbrook is an applied AI lab.
Our first product is Augmenter: an open platform for building, publishing, forking, and installing agents.
Previously, we founded and scaled Lenny, an AI platform for education that reaches more than a million students a year, in thousands of schools, across all fifty US states.
Building Lenny, we put AI agents to work wherever we could, and kept hitting the same limits:
- Codex and Claude (even with automations and skills) aren't purpose-built for the jobs to be done.
- Hermes and OpenClaw agents are black boxes, require constant maintenance, and drift over time.
- Memory, security, and continual learning are genuinely unsolved.
Augmenter is the platform we wished existed.
We're hiring founding engineers. Write to us at team@northbrook.com.
