About Fernando Rojo
Fernando Rojo is Head of v0 at Vercel and is based in New York. His personal site says he built Solito, which Vercel acquired. He also co-founded BeatGig and founded PATOS Shoes. He studied Mathematics and Economics at the University of Pennsylvania, per Crunchbase.
BeatGig, where he was co-founder and CTO, went through Y Combinator in the Winter 2019 batch. PATOS Shoes was a footwear brand that launched through a Kickstarter campaign in 2016. UPenn Venture Lab says PATOS provided work for artisans in Peru.
He maintains open-source developer tools including Solito, Moti and Dripsy. Solito shares code between React Native and Next.js. At Vercel he has been described as Head of Mobile, and his X profile now lists him as head of v0, Vercel's AI prototyping product.
The only angel investment we found in public sources is TesterArmy. Crunchbase lists it as his one personal investment. Press coverage of the round names him among the angels. He does not appear to publish a portfolio page, check size or investing thesis, so none are given here.
TesterArmy raised a €1.04M ($1.2M) pre-seed round in September 2026. It builds AI agents that test web and mobile software. According to The Recursive, investors included Y Combinator, AIP Seed, Eight Capital and Script Capital. Angels in the round included Guillermo Rauch of Vercel, Walden Yan of Cognition, Charlie Cheever of Expo, Zeno Rocha of Resend and Fryderyk Wiatrowski of Viktor, as well as Rojo.
TesterArmy's two founders previously worked at Callstack, a React Native consultancy. Rojo's own work in React Native and Vercel's AI tooling is close to that space.
Rojo has not publicly described his stage or sector preferences, geographies or check size. His one known investment was a pre-seed round in an AI developer tool, and his own work is in mobile and web developer tooling and AI product development. That is background only, not a stated thesis. Founders should ask him directly what he looks at.
