Latent demand: product-market signals

Boris Cherny is the creator and head of Claude Code at Anthropic. What began as a simple terminal-based prototype just a year ago has transformed the role of software engineering and is increasingly transforming all professional work.

We discuss:

1. How Claude Code grew from a quick hack to 4% of public GitHub commits, with daily active users doubling last month

2. The counterintuitive product principles that drove Claude Code’s success

3. Why Boris believes coding is “solved”

4. The latent demand that shaped Claude Code and Cowork

5. Practical tips for getting the most out of Claude Code and Cowork

6. How underfunding teams and giving them unlimited tokens leads to better AI products

7. Why Boris briefly left Anthropic for Cursor, then returned after just two weeks

8. Three principles Boris shares with every new team member
