About
Sail Research builds infrastructure for abundant intelligence — a cost-efficient platform for running leading open-source models for long-horizon AI agents, with OpenAI- and Anthropic-compatible drop-in APIs. Its 'completion window' pricing trades latency for lower token cost, and its Sailboxes offer persistent hosted sandboxes so agents can run indefinitely. The company has raised $80M, with seed led by Sequoia Capital and Series A led by Kleiner Perkins.
