Shofo

Shofo is a Y Combinator-backed company that the World's Largest Video Library. The company participated in the Winter 2026 batch of Y Combinator.

We are building the world's largest video library. We've aggregated billions of videos into a searchable index and use agents to find and label the exact datasets a lab needs on demand.

If a lab needs 100K hours of cooking videos where someone is holding a pan, with reasoning annotations on top, our agents search the index, extract the matching subset, route it through our labeling pipeline, and deliver a custom dataset in days, not months.

Shofo was part of Y Combinator's Winter 2026 cohort, has a team of approximately 4 employees, and is actively operating.
