Understudy Labs on the record

What they shipped

  • From its YC profile: Understudy is an inference cloud. We capture your AI work traces, train smaller models, and automatically deploy them (only when they outperform the expensive model you are currently paying for). Instead of renting the same frontier model forever, your AI infrastructure gets faster, smarter, and cheaper every time it runs. Suppose your product uses Claude for a repetitive legal workflow. Understudy observes successful production runs, learns the specific tools and judgment required for that workflow, and trains a specialized open-weight model. (source)
  • Its own site describes it as: "Understudy helps data-rich teams turn production traces and expert judgment into specialized open models they own." (source)

Who is behind it

  • Luis Manrique, Founder/CEO: Founder at Understudy Labs (YC S26). Previously founding Member of Technical Staff (and founding sales guy) at Gumloop, closing ~$2M in first year. Led Ads ML and also consumer AI as first PM at Instacart's Carrot AI. Prior co-founder/CEO at Ones and Zeros (text-to-SQL using transformers). Early at Wildfire (acquired by Google), then 5 years across Google's ads ML and programmatic platforms. (source)
  • Aamir Poonawalla, Founder/CTO: Founder at Understudy Labs (YC S26). 9 years at Instacart. Built the ads serving and ML infrastructure, auction platform, and experimentation framework. 2nd time YC Founder. MS in Computer Science from Georgia Tech. (source)
