Founding Account Executive - Lithos Ai
About The Position
Lithos builds agentic inference technology that runs frontier open models at full precision on standard GPUs. Its engine ranks highly for output speed, time to first token, and end-to-end latency, and serves startups and large enterprises through a public API or on customer hardware. Founded by Carnegie Mellon computer science professors, Lithos is a small team making one of its first ten hires. The Founding Account Executive will be an individual contributor responsible for turning enterprise interest into revenue and developing Lithos’s initial repeatable sales motion. This person will lead the company’s first enterprise deals from technical evaluation through pilot, pricing, procurement, and signature. They will work closely with the founders and engineers, build new pipeline, document what drives successful deals, and bring customer feedback into product and pricing decisions. The role is hands-on and is focused on closing deals and establishing a sales playbook, rather than immediately managing a team.
Requirements

- A track record of closing six- and seven-figure deals with technical buyers, and the ability to explain how those deals were won.
- Experience as an early or founding sales hire at a startup, building sales processes rather than following established ones.
- Comfort with in-depth technical conversations with engineering leaders and the ability to quickly learn unfamiliar topics.
- Willingness and motivation to remain hands-on, focused on closing deals and building a new sales motion rather than managing a team immediately.
