Amy teaches people how to make products customers actually want. She may be best known for co-creating 30×500, a course that teaches creatives how to build and sell their own profitable products. She's also the co-founder of Noko (formerly Freckle), a time-tracking app for freelancers and teams. If you've read any actually good advice about products or SaaS sales and marketing in the past 15 years, odds are pretty good it passed through her fingertips first.
