Anthropic speed comes from culture, not Mythos

Cat Wu is Head of Product for Claude Code and Cowork at Anthropic, building one of the most important AI products of this generation. Before joining Anthropic, Cat spent years as an engineer and briefly worked in VC. Today, she’s interviewing hundreds of product managers who are trying to break into AI—and seeing firsthand what separates those who thrive from those who fall behind.

We discuss:

1. How Anthropic’s shipping cadence went from months to weeks to days

2. The emerging skills PMs need to develop right now

3. Why you need to build products that don’t yet fully work, so you’re ready when the next model closes the gap

4. Cat’s most underrated AI skill: asking the model to introspect on its own mistakes

5. Why Claude’s personality is core to its success

6. Why Anthropic’s mission alignment eliminates the friction that slows most large organizations

7. Why “just do things” is the most important principle for working at AI-native companies
