AI clip art, coloring pages and worksheets, 250 to 1,000 a day. My daughter uses it every day. This is one of its runs, replayed from Esy's records: the steps, the checks and the cost.

How I made itA letter with no address, a crayon drawing for a clue, and one very determined postman.
Watch the filmThe longer story
I spent a decade shipping production web products, from fuboTV’s streaming apps to Vroom’s online car storefront. That’s where I learned how software gets built, tested and shipped at scale.
Now I build Esy, a workflow platform that makes marketing work (images, pages, video) and records how every piece was made. Three apps run on it: clip.art, which makes 250 to 1,000 clip art assets, coloring pages and worksheets a day; SEOPage, which builds landing pages that get cited by AI and rank on Google; and Compose, a team of agents that researches, writes and fact-checks AI Marketing News on esy.com, with every post approved by me.
I write The Marketing Engineer to teach what those systems taught me, and make the films and creatives to prove they work.
