Head of AI - Roojoom
“When I saw LangWatch for the first time, it reminded me of how we used to evaluate models in classic machine learning. I knew this was exactly what we needed to maintain our high standards at enterprise scale"
David Nicol
CTO - Productive Healthy Work Lives
Having evaluated numerous platforms, LangWatch was the only one that meaningfully resolved our quality gaps. The difference has been substantial
Lane Cunmmingham
VP engineering - GetGenetica - Flora AI
“LangWatch has brought us our monitoring and evaluations with an intuitive analytics dashboard. The Optimization Studio with DSPy brings the kind of progress we were hoping for as a partner."

AI Architect, Entropical AI agency
"I’ve seen a lot of LLMops tools and LangWatch is solving a problem that everyone building with AI will have when going to production. The best part is their product is so easy to use."
