After bookkeeping, payments, tea and a world title in Taekwon-Do, Catherine Jue found her next hard problem hiding in plain sight: the browser. At Kernel, she is turning it into infrastructure that AI agents can use at production scale.
Kernel is a San Francisco startup building browser infrastructure for AI agents and web automations. Its cloud browsers launch in a few hundred milliseconds, persist login state across workflows, and evade bot detection, letting developers point agents at the live web without operating their own browser fleet. Backed by Accel and Y Combinator, Kernel raised $22M and says it is used by thousands of teams building agents, including Cash App and Rye.
