Product Hunt's discovery site for genuinely useful technology has been bought by AngelList. The terms of the deal weren't disclosed, however Recode is putting the number at around $20 million. The acquisition involves a mixture of cash and stock, and will see ProductHunt "remain an independent platform," according to its CEO Ryan Hoover. "We'll continue to use excessive emojis, drink Philz, and build in public with our community," he wrote on Medium. ProductHunt launched in 2013 with a simple premise: surface the hottest startups and services. It's since become a Silicon Valley darling, expanding into games, books and other categories.
