About us
Langfuse is building the open source LLM engineering platform to help teams build production-grade LLM applications faster (Why Langfuse?).
We are excited about the potential of LLMs and generative AI and the impacts it will have on all of us. Doing our part in accelerating this shift is our mission.
We initially realized the pains of solving problems with LLMs during Y Combinator's W23 batch in San Francisco. We now have two offices, a larger one in Berlin, Germany (with a focus on product & engineering) and a smaller one in San Francisco (with a focus on marketing & sales). We hire product & engineering remotely across Europe, with a week onsite per month in Berlin.
In January 2026, we joined ClickHouse to accelerate even further. Learn more about our story and mission.
