About Tesora

Tesora builds frontier AI agents for actuaries at P&C carriers, reinsurers, and MGAs. The agents handle the assembly, pulling the data, running the method, and deploying the rater, while you review the work and make every call. We deploy inside the stack you already run, on your infra and under your IT team's control, with no shared servers and nothing to rip out. Your data never trains our models, or anyone else's. We treat this as a partnership so we stay hands-on until the work is live and holding up in production. That standard runs through our security posture too: SOC 2 Type II certified, with a full audit trail behind every change.

The part of the job that matters is actuarial judgment, and we automate everything around it so you get back to the work only you can do. Built by AI technologists and actuaries who want to see this exist and backed by Y Combinator & other top investors.
