Understudy Labs
Understudy Labs is a San Francisco AI infrastructure startup (Y Combinator S26) that helps data-rich teams replace expensive frontier LLMs with smaller, specialized models they own. Its open-source toolkit captures production traces from existing agent workflows, benchmarks cheaper open-weight models against them, and only ships a replacement once a held-out evaluation beats the incumbent - promising comparable quality at a fraction of the cost and latency.

Siddharth Sridharan is the Co-Founder and CEO of Spendflo, an AI-native procurement platform that helps fast-growing and enterprise companies manage SaaS vendor relationships and cut software spend.
