Hi, I'm Max, CTO and co-founder. Langfuse is the open-source LLM engineering platform — tracing/observability, evals, and prompt management — used by tens of thousands of teams to ship, debug, and improve their LLM and agent apps.
Earlier this year, Langfuse joined ClickHouse ($400M Series D led by Dragoneer, $15B valuation). That gives us the best of both worlds: startup-speed, ownership, and roadmap control, backed by the scale, resources, and equity upside of a category-defining infra company.

ClickHouse's take: https://clickhouse.com/blog/clickhouse-acquires-langfuse-open-source-llm-observability
Right now we're focused on helping customers segment their traces, surface insights from them, and ship changes to their agents faster — observability at serious scale, plus the product surface engineers actually live in day to day. See what we're building: langfuse.com
