About Us:
We are a well-funded AI infrastructure startup (currently in stealth mode) that has been named to a list of the 60 most disruptive AI startups, raised a $25M seed round, and already has paying clients . We help engineering teams cut the cost of agentic AI workloads without sacrificing quality — letting them keep using the coding tools their developers already love (Claude Code, Codex, Cursor) while routing the underlying workload to leading open-weight models at a fraction of the cost of expensive frontier models. We also give teams control over spend on long-running agentic inference workloads — chat agents, document classification, ticket sorting — by trading latency for dramatically better token economics.
