MacHeist was a website that bundled and resold Mac OS X software. The site conducted marketing through challenges (or "heists") that allowed customers to win software licenses and/or discounts; and sold software in bundles that increased in size as more customers purchased the offer. The site was founded by John Casasanta, Phillip Ryu, and Scott Meinzer. After a final promotion in May 2016, the original incarnation went offline. As of November 2018, the website is a front-end for marketing by native advertising company StackCommerce.
