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.
