What leading YC teams say about Extend
Pedro Franceschi
CEO, Brex
Extend outperformed every solution we tested—other vendors, open source, and even foundation models. It now powers key document workflows across 30,000 customers, helping us build the most intelligent and modern financial platform out there.
Matt Hodgson
CTO, Vendr
We did a bakeoff, and Extend had the best results of any solution on the market. It eliminates an entire class of engineering problems around accuracy that we don't want to worry about.
Adam Litton
Staff Software Engineer, Checkr
Extend eliminates the ongoing maintenance cost of model tuning, scoring, evaluations, and more. We're able to focus on innovating on our core experience, instead of managing the infra.
