The most successful YC companies aren't always the loudest. They're the ones that survive the "Valley of Death" to become indispensable infrastructure.

In this episode, I sit down with Grant Shaddick, founder of Tella (YC W20), the video tool that has quietly taken over the YC ecosystem. We dive into the grit required to build a category leader, why they chose to stay lean while others over-raised, and how AI is finally killing the "video editing" bottleneck.

What you’ll learn:

• Why "boring" infrastructure often outperforms "hype" AI startups.
• The reality of the startup "Valley of Death" and how to survive it.
• Why a high valuation can actually be a founder's biggest trap.
• The future of agentic video editing: from tools to outcomes.
• The secret behind Tella’s viral adoption among YC founders.

YC just added one question that quietly changes what it means to be a founder.

And it’s not about your TAM. It’s not about your pitch. It’s about how you use AI to build.

In this episode of Lobster Talks, we break down YC’s newest application change, the rise of coding agents like Claude Code, and what this signals about where startup building, and venture capital is heading next.

We also go deep on YC Roaster, Lobster Capital’s new initiative helping founders improve their YC applications using AI + YC alumni review.

Here’s what you’ll learn:

- Why YC’s new “coding agent session” question is a founder filter

- How vibe coding is becoming table stakes in 2026

- What 20,000 YC applications really signal about global founders

- Why traction keeps rising as the YC acceptance bar

- How smart VCs are building internal tools and why most aren’t

- Why the best founders and funds pivot fast

This is a behind-the-scenes look at how YC evaluates builders today.

Most people treat their bodies like a car they only fix after it crashes.

Max Berthelot and Lucis are rewriting that script by turning longitudinal blood data into a high-margin, preventive software play.

In this episode, we sit down with Max Berthelot, founder of Lucis (YC S25), to discuss why "Function Health for Europe" is one of the most compelling arbitrage opportunities in the venture world.

We dive into the cultural shift of paying for health in Europe, the technical challenge of scaling doctor-supervised AI, and the relentless execution required to expand across five countries in record time.

What you’ll learn:

- Why blood data is the "Gold Rush" of the next decade.

- The YC strategy for conquering fragmented European markets.

- How to maintain "San Francisco Velocity" while based in Paris.
