Kernel provides crazy fast, open source infrastructure for AI agents to use the internet. Our API allows developers to instantly spin up secure browsers and automate anything on the web. We handle all the hard problems of running browser-based agents in production: agents x user credentials, autoscaling, bot detection, and human-in-the-loop workflows.
We’re used by teams at Cash App, Vercel, Framer, and over 5000 developers for tasks like QA automation, RPA, virtual assistants, and CUA RL environments. We've raised $22M from Accel, YCombinator, Vercel, Paul Graham, Solomon Hykes (Docker), David Cramer (Sentry), Charlie Marsh (Astral), and more.
We're hiring our founding marketer. Some of our marketing is already working well and just needs an owner to take it further. Some of our marketing motion doesn't exist yet. You'll be responsible for both: figuring out what Kernel needs next, and actually making it.
