Helen built the analytics function at Crocs during its run from $1B to $4B, and now she's showing you how to build a persona-based testing tool inside Claude Cowork. Synthetic pre-market testing means you run multiple landing page narratives against real persona types before a dollar hits paid traffic. You'll leave with a working tool, a tested page, and more signal than any gut check gives you.
