This reactor in Houston, Texas, represents a whole new approach to chemical manufacturing. We make chemicals in a completely new way. We started off by making hydrogen peroxide.Now we sell products for water treatment, national defense, infrastructure, agriculture, you name it, we make a chemical for it. >> The story of Cyogen is as scrappy as it gets. It all started with this prototype built out of PVC pipes the founders bought from Home Depot.>> In its heyday, this did 12,000 bucks a month in revenue. Fas ...

At poetic, what we're building is a recursively self-improving system. And so recursive self-improvement is this uh you know kind of the holy grail of AI where the AI is making itself smarter. The core insight that we had is that uh we could do recursive self-improvement far faster and cheaper than all of the other ways that people had been proposing to do this.Most of the approaches out there involve, you know, they require you to train a new LLM from scratch. And training LLMs from scratch costs, you know ...

In this episode of The Lightcone, we talk with Mukund and Madhav Jha, the founders of Emergent - an AI platform that lets anyone build and ship production-ready software. In just eight months, users have created more than 7 million apps on Emergent, with the number doubling in just the last 45 days. We discuss how they built one of the most powerful AI coding agents, why they focused on non-technical users and what it's like building for a global audience from India.

We're excited to announce that for the first time ever, we'll be hosting Startup School in India. We're coming to Bangalore on April 18th for a very special 1-day event where the best builders and hackers from across India will convene to discuss the latest in tech and startups. Joining us will be the founders of incredible Indian companies backed by YC including Razer Pay, Misho, Grow, and Emergent.We're thrilled to meet the next generation of Indian founders and can't wait to see you there. ...

I think it is very possible that the first people to live to a thousand are alive right now. It still takes some suspension of disbelief because I think biotech has just been so incremental. One of the things that's so exciting about what's happening now is that no longer really feels so incremental to me.I think that BCI we're going to come to see is not is not a specific product. I think there going to be a bunch of BCI companies going after different applications where different types of probes will make ...

It's easier than ever to design with AI tools, but that doesn't mean you should always accept all changes. So today, I'll be joined by Raphael Shod to look at the good, the bad, and the ugly of AI assisted design and sort through how to use these superpowers to stand out. Welcome to another design review. All right. Today I am thrilled to be joined by Raphael Shad, one of the newest visiting partners here at YC. And Raphael was the co-founder of Kron, a modern calendar tool, which you sold to Notion a while ...

YC's startup school is back and we want you to join us. We're going to hand select the most promising builders in the world and fly them to San Francisco for 2 days July 25th and 26th to discuss the cutting edge of tech and startups. Expect to hear from worldclass speakers including Jensen Huang, Sam Olman, Alexander Wang, and Jeff Dean.You'll also get direct access to YC partners, top alumni, and fellow builders in small groups and one-on-one. If you're a top undergrad, grad student, or researcher in CS, M ...

The world is changing so quickly. This is probably a little bit obvious, but you should just try things and and like every day do something with AI. Last summer, I took a weekend and used um GPT5 to help me build an iPhone app.I hadn't done that in a decade. And yeah, it's so fast and so easy. And that was, you know, an age ago. That was like 8 months ago.Uh now it's even faster and easier. Don't limit yourself. like anything that you imagine, you should just try to use AI and see how far you can get with i ...

continuing to trace the exponential. I think what will happen is coding will be generally solved for everyone. I think we're going to start to see the title software engineer go away and I think it's just going to be maybe builder, maybe product manager, maybe we'll keep the title as kind of a vestigial thing, but the work that people do, it's not just going to be coding.It's software engineers are also going to be writing specs. they're going to be talking to users like this thing that we're starting to se ...

Welcome to another episode of the light cone. Things are a bit different around here. For one thing, Claude Code has totally taken over my life.And if Jared is any indication, I think OpenClaw maybe has taken over his. >> I've been really addicted to this new site called Moltbook, where people have unleashed their AIS to interact in the first ever AI agent-only online community. I am here impersonating my personal OpenClaw instance right here.Okay, I can't do this, guys. We got to take this off. Okay, we've ...
