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.
Kevin Xu
Kevin Xu is the Chairman and CEO of ClinChoice, a global full-service contract research organization (CRO) with more than 30 years of history, roughly 4,000 staff, and operations across 15+ countries. He arrived in the corner office from the investor's side of the table: for over 15 years he was a Managing Director at Goldman Sachs, where he built and ran the firm's Asia-Pacific Healthcare and Life Sciences investing practice, leading deals across biotech, pharma, medtech, CROs/CDMOs and digital health. Trained in neuroscience and clinical psychology before finance, he is an outspoken advocate for destigmatizing mental illness and an unlikely wake-surfer.
