Inside Claude Code From the Engineers Who Built It

At Every, the team credits Claude Code with transforming the way they work.

They now ship to codebases they barely know, each new feature makes the next easier to build, and even non-technical teammates confidently use the terminal.

To explore how this happened, AI & I host Dan Shipper invited Claude Code’s creators—Cat Wu (@_catwu) and Boris Cherny (@bcherny) from Anthropic AI—to discuss what they’ve learned from building one of the most beloved AI engineering tools in the world.

This episode is a must-watch for anyone—technical or not—who wants to understand how to use Claude Code like the people who built it.
