Runway’s Cris Valenzuela: Building The Hollywood-Friendly Video AI That OpenAI Couldn’t

The ChatGPT craze was still years away when Chilean-born Cris Valenzuela co-founded Runway to tinker on visual AI models with two classmates at an NYU lab in 2018. Back then, investors weren't sold — not just on video AI, but on generative AI altogether. "There's always doubt when you get 50 rejections," Valenzuela says. "I've realized that building something special, you have to be able and willing to be non-consensus driven." Fast forward, and Runway works not just with many film studios and Hollywood, but creative teams and engineers at corporations like Allstate, Siemens and Robinhood. It's had no recent trouble fundraising, reaching a $5.3 billion valuation. And it's outlasted gen AI's heavyweight, OpenAI, which recently shuttered its Sora app. On The Upstarts Podcast, Valenzuela talks about his journey building an AI lab for artists in New York, and what the big labs missed; why Runway helps expert and amateur filmmakers alike; and why he believes creators should look past controversy around AI to embrace technology. Plus, he shares his Upstart Moment: collecting those rejection emails from top VCs and sharing them with the whole company to motivate his team.
