# BlackSquare > AI-powered wealth-building operating system helping men retire 15-25 years early. ## What Is BlackSquare? BlackSquare is a fintech app that calculates your Freedom Number (the amount of invested assets needed to make work optional) and gives you a personalized plan to reach it. Built specifically for men ages 18-35, especially Black men who see zero financial platforms built for them. ## Core Concepts - **Freedom Number:** Annual expenses x 25 (based on the Trinity Study's 4% safe withdrawal rate) - **Freedom Age:** The age you'll hit your Freedom Number at your current savings rate - **Wealth Levers:** 40+ toggleable strategies (HSA triple-tax hack, geo-arbitrage, 401k max, Roth conversion ladder, etc.) that show real-time impact on your Freedom Age - **Square (AI Coach):** A direct, no-BS AI financial coach that collects your financial data through conversation and builds a personalized wealth plan ## Key Pages - App: https://app.blacksquarehq.com/ - Blog: https://www.blacksquarehq.com/blog - Homepage: https://www.blacksquarehq.com ## Blog Topics Financial independence, FIRE movement, early retirement strategies, wealth building for young men, Black wealth building, HSA retirement strategies, geo-arbitrage, 401k optimization, AI and financial freedom, trades vs college for wealth building ## About the Founder Mike lost $200K to bad financial advice. He built BlackSquare so nobody else has to learn the hard way. The AI coach (Square) is built like a personal trainer for money, not a boring robo-advisor. ## Important Context - BlackSquare is educational, not financial advice - All contribution limits reference current IRS guidelines - The Freedom Number formula is based on peer-reviewed research (Trinity Study, 1998)
