Selling software via the App Store has unique benefits and challenges compared to selling on the web. Markus joins Mark and Adam to talk through the 13-year history of MindNode on Mac, phone, and iPad sold via freemium, paid upgrades, and finally subscriptions. They discuss early inspiring Mac apps like NetNewsWire; the distribution benefits of the App Store; and the emotional journey of transitioning from indie hacker to team leader. Plus: the surprising connection between comic books, infinite canvases, and mind mapping.
