About
2signal is the testing and reliability platform for AI agents. We help teams ship agents that work — not agents that work sometimes.
AI agents are powerful but unpredictable. We're building the tools to make them reliable.
Traditional testing doesn't work for non-deterministic systems. Agents hallucinate, regress without code changes, and fail in ways no unit test can catch. 2signal gives teams the instrumentation, evaluation, and monitoring they need to ship with confidence.
We started 2signal after watching teams deploy AI agents with no way to know if they were actually working. The monitoring tools built for traditional software — uptime checks, error rates, log searches — don't tell you whether an agent gave a good answer or a hallucinated one.
We're based in Austin, TX, and building the platform we wished existed when we were shipping agents ourselves.
Developers first
If it takes more than 3 lines to instrument, we failed. The SDK should disappear into your code.
Measure everything
Every trace scored, every regression caught. Opinions are fine — data is better.
Ship fast, stay reliable
Move fast and test things. Velocity without visibility is just recklessness.
