Langfuse

I'm Max, co-founder and CTO of Langfuse (YC W23) - we're building open source LLMOps dev tooling. We started with observability and have branched out into more workflows over time (evals, prompt mgmt, playground, testing...). We have a bunch of traction and are looking for our fourth to sixth hire in scaling and building feature depth. We value quality in engineering at Langfuse: We try to find elegant solutions to complex engineering challenges, and we invested significant effort in enhancing our production setup (infra as code, top observability setup and more). If you'd love shipping in open source, writing about what you work on and working hard with super interesting and sophisticated customers (devs) - reach out!
