AfterHour

AfterHour is a San Francisco social trading app that lets retail investors link their real brokerage accounts and post their actual positions - in full dollar amounts - to a public feed under a pseudonym. The twist is verification: you can talk your book, but the app proves you're holding what you claim. Founded by Kevin Xu, the WallStreetBets folk hero known as 'Sir Jack A Lot' who turned roughly $35,000 into millions during the meme-stock era, AfterHour combines verified portfolios, live stock chat rooms, and real-time trade signals into one community. It raised a $4.5M seed round led by Founders Fund and General Catalyst in June 2024.
