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.

Chapter's Cobi Blumenfeld-Gantz: From Palantir To $3B Medicare Disruptor

When Cobi Blumenfeld-Gantz's parents struggled to navigate Medicare—faxes, phone calls, even a trip to the Social Security office—he figured someone had built a better way. Nobody had. So, in 2020, he co-founded Chapter: a startup focused on connecting Americans to better Medicare plans, saving seniors thousands of dollars per year. Among legacy healthcare players, that hasn’t made him many fans. “I am one of the most hated people in the industry,” he says. “I’m bad for business.” On The Upstarts Podcast, Blumenfeld-Gantz shares his journey from foreign policy studies to forward deployed engineer at Palantir; how Chapter’s nationwide database of Medicare plans helped it reach $100 million in revenue and a $3 billion valuation; and why he proposes a twist on a typical startup metric: product-market-channel fit. Plus, he shares his Upstart Moment: when last year’s government shutdown cut off Chapter's data right at the opening of Medicare's busiest enrollment window, and his team had one week to reverse-engineer their way out.

Cohere's Aidan Gomez: The Canadian Founder Taking AI Models To The World, Not Just Big Tech

A self-described "shy nerd" from rural Ontario, Aidan Gomez doesn't like to scream his startup’s name from the rooftops. But the co-author of the landmark ‘Attention Is All You Need’ paper is quietly building one of AI's most important infrastructure companies — one focused on bringing its benefits to the wider world outside Silicon Valley. Toronto-based Cohere works with major enterprises and G7 governments, providing secure models for them to build everything from email-summary apps to onboard ship telemetry on top. Revenue grew 6x last year, past a reported $240 million; with $1.7 billion in total funding, an IPO is in its sights. On the Upstarts Podcast, Gomez talks about his journey to co-developing the Transformer architecture that underpins modern AI; why he sees AI as the best shot at restoring global growth and democratic resilience; and why it’s so important that more nations than the world’s biggest benefit.

Decagon’s Jesse Zhang: Closing Customer Service Doom Loops With AI Concierges

When it comes to calling customer support, startup CEO Jesse Zhang knows your pain.  ”It's just a very frustrating experience, because you're stuck in a loop,” he says. In 2023, he and co-founder Ashwin Sreenivas launched Decagon to solve the problem with powerful new technology: AI agents. Today, customers like Avis Budget Group, Duolingo and Fanatics all work with Decagon, helping it reach a $4.5 billion valuation. But as AI unlocks new possibilities in support, Zhang faces serious competition from more established and better-funded rivals. On the Upstarts Podcast, Zhang shares how Decagon wins by using speed as a weapon, but not a moat; why 10x better products can fend off the big AI labs; and how his AI concierge can help future customers beyond just solving problems. Plus, he shares his Upstart Moment: winning uphill sales battles with a bottoms-up hustle that turned “red dots” into green buyers.

Axiom’s Carina Hong: Solving Math’s Hardest Problems With AI, And AI's Problems With Math

Just nine months ago, Morgan Prize-winning prodigy Carina Hong was still on an academic track, pursuing a joint law degree and math PhD at Stanford. Now, as the founder of startup Axiom Math, she runs one of the most promising challengers in a new, fast-paced category: AI for math. Recently valued at $1.6 billion, Axiom has already solved some of math’s most challenging problems, and Hong hopes it can help researchers advance the field. Her bigger ambition? To power real-time math-based verification of AI-generated code, to do away with vibe-coded slop. On this episode of The Upstarts Podcast, Hong shares her founder journey from immigrant at MIT to Oxford, and ultimately dropping out of Stanford; how she’s learning as a first-time founder to help Axiom compete in a red-hot new category; and her Upstart Moment when Axiom took the world’s hardest college-level math test.
