Coding agents are no longer a distant idea—they're already starting to reshape how we work.

YC's Tom Blomfield and David Lieb discuss how AI coding tools are transforming software development, why small, high-agency teams will be able to do what once took armies of engineers, and why there's never been a better time to start something new.

They explore the bigger picture too: a future where there's abundance, knowledge work becomes more accessible, and founders have more leverage than ever before.

If you're thinking about building, there's no better moment than right now.

AI can't yet one-shot an entire product—but with the rise of vibe coding, it's getting close.

This is a playbook for anyone who wants to get the most out of vibe coding and build faster.
