Founding Account Executive - Lithos Ai

About Lithos

Lithos builds the fastest agentic inference on the planet: frontier open models at full precision on standard GPUs. Our engine currently holds top spots on Artificial Analysis for output speed, time to first token and end-to-end latency. We serve inference to growing startups as well as FT500 companies through a public API or on their own hardware.

Lithos was founded by Carnegie Mellon computer science professors who spent years turning systems research into a product. We are a small team, and this is one of our first ten hires.

Why this role matters

We have serious enterprise interest from well-known, AI-forward companies, and we need someone to turn it into revenue.

This is deliberately an individual contributor role. We don't yet know our repeatable sales motion well enough for anyone to build a team around it. We need one great seller who can run our first enterprise deals end to end, close them, and tell us what actually wins. What you learn becomes the playbook the rest of our sales organization is built on.
