Josh Le is Co-Founder and CTO at Hue, a Y Combinator-backed (Fall 2026) AI startup that enables teams to test and improve AI agents under realistic, production-mirroring conditions.

Josh built his engineering foundation at top-tier companies including Apple, Gusto, Wayfair, and August, before taking on startup roles at SendBlue (YC S23) and Sixtyfour (YC X25), accumulating deep experience across consumer and enterprise engineering.

Josh is a Kleiner Perkins (KP) Fellow and a multi-time hackathon award winner, including a 2nd Place finish at the NYC Generative AI Hackathon and a 1st Place win at KleinHacks, reflecting his passion for building at the frontier of AI.

At Hue, Josh leads all technical development, architecting a platform that captures real production usage of AI agents and converts it into repeatable, high-fidelity test suites that preserve the tools, data, and state of actual runs.

Hue is part of Y Combinator's Fall 2026 batch and is actively tackling one of the most critical challenges in the AI agent era: ensuring reliable, real-world agent behavior at scale.
