Eligibility & conditions
Langfuse is an open-source LLM observability platform for tracing, evaluating and monitoring AI agents and LLM applications. Its startup program takes 50% off the entire Langfuse Cloud bill for 12 months, applied to every invoice, after which the account rolls onto standard pricing. Eligibility is unusually wide for this category: bootstrapped companies qualify, and the ceiling is 5 million USD raised rather than a seed-stage-only or VC-portfolio-only rule. Review is automated and usually completes in under 24 hours.
