We help AI teams get their agents safely to production.
LangWatch is the AI agent engineering platform, and the open-source frameworks behind it, that developers use to ship reliable agents with confidence.
We lived the fragility of AI in production.
We saw the same problem from two sides: agents that demo beautifully and then break in the messy reality of production, with no systematic way to catch it. Testing AI was slow, manual, and owned by whoever happened to be closest to the incident.
LangWatch is the platform we wished we had: simulate real conversations before launch, evaluate every release, and watch quality in production, so shipping reliable agents is the default, not a heroic effort.
Make AI reliable enough that teams can focus on strategy and creativity, while we help ensure their AI behaves as expected.
Built by engineers who shipped AI the hard way.
Five values we actually use.
Make it about the customer
Every decision starts with the team shipping AI and the people they serve.
Make it happen
Bias to action. We would rather ship, learn, and correct than wait for certainty.
Make it together
Engineers, product, and domain experts own quality as one team, not a hand-off.
Scale through leverage
Automate the repeatable so people spend their time on the hard, human parts.
Ship today
Tomorrow brings new challenges. We close the loop on the ones in front of us now.
