Brett Adcock's Hark Labs wrapped its viral "free pizza" giveaway: pizzas sold out as usage surged to unprecedented levels, breaking things along the way.

The core of the stunt was an AI agent completing the entire ordering flow — logins, computer use, and payment — powered by their model Handoff. Thousands of Friday-night pizzas were delivered fully end to end, with 203,500+ browser sessions run in total. The app also climbed to #58 on the App Store.
