A · Case · Midas
A marketing and design team, in software.
I built Midas for Coinme in ten weeks, inside the most regulated ad category there is. It started on 25 January 2026 as two skills in my own agent, Kane, and grew into a team that wrote, designed, screened and rotated its own A/B creative, then audited its own numbers until they were true.
Chapter 1
It argued with its own numbers
Midas’s first read on return looked great. Then it took that number apart: gross revenue isn’t margin, and the real return was half what it first reported. It caught an efficiency metric it had made up and re-queried it, cut an assumed card margin from 5% to 2%, and found Android revenue from Meta filed under the wrong source. Most AI marketing tools flatter you. This one checked itself first.
