Sail Research
Sail is the AI inference provider designed for background agents. We supply tokens at extreme scale, for any task where thoroughness is more important than speed. Our hardware and software stack is designed purely around efficiency; we sacrifice some latency to let you (sustainably) deploy billions of tokens towards your most interesting and challenging AI tasks. More agents, thinking longer, can do incredible things.
About us
We are systems nerds with commercial focus. The team comes from NVIDIA, Stanford, YC, Apple, and robotics companies. Everyone codes: our distributed systems team loves Rust 🦀, GPU performance team pushes the speed-of-light in CUDA, and we dig into the details of AI inference engines like SGLang. If you like GPUs, the elegance of simple systems at scale, or generally the frontier where hardware meets software, we're just like you. Let's talk!
Why
Agents are getting really good at running autonomously. In 2026, they will be good enough to make meaningful progress on the world’s hardest problems, given sufficient tokens. Our job is to keep the tokens flowing, letting no compute go to waste. If we do this right, we will dramatically increase marginal intelligence per dollar and build a generational company.
