From the founders
We started LangWatch because we both experienced the same challenge from very different angles: while everyone talks about AI, turning it into real, reliable value is still incredibly hard. Manouk felt this firsthand as a non-technical founder building AI-driven products, the lack of clarity, predictability, and confidence around AI made even simple decisions difficult. Rogerio saw the same problem inside Booking.com, where building AI applications at scale exposed how fragile, opaque, and hard to test AI systems really are.
AI has enormous potential, but most companies still struggle to make it work in production. We built LangWatch to change that — to give teams the visibility, testing, and confidence they need to ship AI products that actually perform.
Our Mission
Our mission is simple: make AI reliable enough that companies can focus on strategy and creativity, while we help ensure their AI behaves as expected and delivers real value.
We’re building the reliability layer that lets teams ship AI agents with confidence, whether they’re reasoning across long conversations, coordinating complex workflows, or operating through voice.
Modern agents fail in ways that are subtle and hard to predict. LangWatch gives teams a way to uncover those failures before they reach customers: realistic simulations, automated evaluations, deep observability, and guardrails that surface regressions early.
By bringing testing, evaluation, and production-grade monitoring into one platform, LangWatch helps AI teams move quickly without compromising trust or safety. From fast-moving startups to enterprise AI products, teams rely on LangWatch to ensure agents behave consistently, recover gracefully, and deliver reliably in every context.
LangWatch is where agent reliability is engineered, not hoped for.
