## Summary

Merge co-founder and CEO Shensi Ding uses Codex to redesign a feature, having it draw on Merge's existing design system and propose different approaches. She says the lower cost of testing ideas has changed how she runs the business, and Merge employees are encouraged to choose their own tools and build workflow tools without waiting for engineering.
