The interview discusses the evolution of the online persona "Sir Jack" and the creation of the trading-centric social media platform AfterHour. Initially, Sir Jack emerged accidentally from the founder's desire to share stock market gains on Reddit during the pandemic. As his posts gained traction, a community developed around discussions of retail trading, highlighting the need for a verified yet pseudonymous platform. This led to the creation of AfterHour, which aims to fill the gaps in existing platforms by offering a space for traders to connect anonymously while verifying their trades through real financial institutions. The founder emphasizes the importance of building a differentiated social network with unique features like due diligence tools, and highlights the strategic approach to growth, focusing on community engagement and retention. The platform's design leverages user insights and market events to enhance user experience, while the founder's dual role as an active trader and community leader helps inform its development.
