Cursor Head of Design Ryo Lu has spent his career at the intersection of design and engineering—from building fan sites as a kid to designing products at Stripe, Asana, and Notion. Now he's rethinking how software itself gets made.

On this episode of Design Review, Ryo joins YC's Aaron Epstein to break down how great product websites communicate what a company does. They walk through sites from early-stage startups, calling out the small choices in structure, clarity, and brand that help users understand a product instantly — and the ones that get in the way.

Starcloud recently made history by launching a satellite with an NVIDIA H100 into orbit — the first time a GPU that powerful has ever operated in space. It's the first step toward building AI data centers in orbit, powered by continuous sunlight and cooled by radiating heat into deep space.Their approach could one day rival the world's biggest data centers while using less energy, zero fresh water, and far lower emissions.In this episode of Hard Tech, YC's Aaron Epstein visits Starcloud's HQ, where co-founders Philip Johnston, Ezra Feilden, and Adi Oltean explain how they built a working prototype in just 15 months — and why big tech is racing to space for AI compute.

Most founders think hiring is about interviewing. But it's actually about selling.For Startup School, Juicebox co-founder & CEO David Paffenholz joins YC's Harj Taggar to share how early-stage founders can find, pitch, and close top engineering and sales talent— from crafting better outreach to winning great hires from Big Tech— even when you're an unknown startup.

Nearly every modern AI model, from ChatGPT and Claude to Gemini and Grok, is built on the same foundation: the Transformer.In this video, YC's Ankit Gupta traces how AI learned to understand language — from early RNNs and LSTMs to attention mechanisms and the breakthrough 2017 paper Attention Is All You Need — the discovery that unlocked the modern AI era.

Every founder faces moments where they’re not sure what to do next — such as how to go to market with AI products, when to pivot, and who/when to hire.

In this episode of Office Hours, YC partners Pete Koomen, Brad Flora, Nicolas Dessaigne, and Gustaf Alströmer answer real questions from founders and share stories about how great teams build conviction, learn faster, and make better decisions as they grow.

For years, we've heard two major narratives about AI. One predicting the end of human work, the other dismissing it as hype. The truth is more nuanced, and more hopeful.From radiology to software engineering, the pattern repeats: as technology makes tasks cheaper and faster, demand for human creativity and judgment grows.YC's Garry Tan explores what history, economics, and real companies show us— that technology doesn't replace people, it redefines what we can do.

Karri Saarinen is the co-founder and CEO of Linear, the issue tracking tool used by thousands of high-growth companies. Before Linear, he was the first designer at Coinbase and later a lead designer at Airbnb.On Design Review with YC's Aaron Epstein, Karri shares how his design background shaped Linear’s product philosophy, why quality and craft matter from day one, what founders should look for when hiring, and how AI is changing the way teams build. It’s a deep dive into building products that truly stand out.

Paul Gross and his team at Remora are trying to do something that’s never been done before.

They're building mobile carbon capture devices for commercial trucks and trains—capturing CO2 from moving vehicles before it enters the atmosphere, then turning those emissions into revenue by selling it to customers that can turn the liquified CO2 into new products.

In this episode of Hard Tech, YC's Gustaf Alströmer visits Remora's headquarters outside Detroit to see how a recent college grad with no engineering background is helping transform the $2 trillion transportation industry.

Jordan Fisher is the co-founder & CEO of Standard AI and now leads an AI alignment research team at Anthropic. In his talk at AI Startup School on June 17th, 2025, he frames the future of startups through questions rather than answers—asking how founders should navigate a world where AGI may be just a few years away.He surfaces the big questions startups should be asking in the age of AGI: Should you even start a company right now? What happens when software becomes commoditized? How do you build trust as teams shrink and AI takes on more responsibility?
