YC has become a surprising force in the hard tech world, funding startups building physical products from satellites to rockets to electric planes. In this episode of Lightcone, we go behind the scenes to explore how YC advises founders on their ambitious startups. We also take a look at a number of YC's hard tech companies and how they got started with little time or money.

If you read articles about companies like OpenAI and Anthropic training foundation models, it would be natural to assume that if you don’t have a billion dollars or the resources of a large company, you can’t train your own foundational models. But the opposite is true. In this episode of the Lightcone Podcast, we discuss the strategies to build a foundational model from scratch in less than 3 months with examples of YC companies doing just that. We also get an exclusive look at Open AI's Sora!

One trait that many great founders share is conviction. In this episode of Dalton & Michael, we’ll talk about finding confidence in what you're building, the dangers of inaccurate assumptions, and a question founders need to ask themselves before they start trying to sell to anyone else.

In the first episode of the Lightcone Podcast, YC Group Partners dig into everything they have learned working with the top founders building AI startups today. They share the ideas that are working particularly well, mistakes to avoid, and take a look at the competitive landscape among the current AI giants.

Based on the thousands of companies YC has funded over the years, the biggest common element between all successful startups is having technical talent on the founding team. But what do you do if you don't know how to code? You may think you can get by using no-code tools, part-time consultants, or dev shops to bring your startup idea to life. But that thinking is wrong. In this episode of Dalton & Michael, we’ll discuss exactly why that is and why recruiting a technical co-founder is the single biggest way to create value as someone trying to start the next big thing.

Casetext started out in 2013 as a crowdsourced law library — a sort of “Wikipedia meets Reddit” for the law. Ten years later, Casetext is one of the biggest wins to date in AI, capable of turning weeks of arduous legal work into hours or minutes. Just months ago it was acquired for $650 million dollars.

What happened between those two points?

For this episode of Main Function, YC President Garry Tan sits down with Casetext co-founder Jake Heller to learn the real story of their 10-year “overnight” success: the 3 a.m. origin story, how the company evolved as fast as tech would allow, and the “magic demo” that helped turn Casetext into a rocket ship.
