About Sphinx Labs

Sphinx Labs is a YC-backed, $7M+ seed-stage startup building AI agents that tackle financial crime — the invisible backbone of global corruption. Trusted by leading banks and fintechs across the U.S., Canada, Europe, and LatAm, Sphinx's customers have seen 90% less manual work and 4× lower costs. The team is tackling three hard technical challenges: browser agents for the invisible web (legacy government portals, unstructured data), a global risk graph reconciling entities across borders and shell structures, and scalable inference for millions of daily transactions.
