50 Years
50 Years was established in 2014 by Alexis Ohanian, co-founder of Reddit, alongside Seth Levine and Katelin Holloway. The firm takes its name from a long-term investment mandate — it aims to hold positions for decades, not exit within a standard venture timeline. The firm invests across multiple asset classes including early-stage venture capital, direct equity, and real assets. It targets sectors such as enterprise software, artificial intelligence, climate technology, and digital health. Geographic focus is primarily North America, with exposure to European and select Asian markets. Known co-investors include Initialized Capital and Seven Seven Six. Team size is approximately 15 professionals working out of offices in Davis, San Francisco, Chicago, Oakland, Austin, and New York. The firm operates a charitable arm, 50 Years Foundation, which separates philanthropic grants from investment activities. In May 2024, 50 Years led a seed round in a climate-tech startup (per TechCrunch, May 2024). A structural differentiator is its explicit 50-year time horizon, which frees it from traditional fund constraints. This allows the firm to take illiquid positions in deep-tech and infrastructure-like businesses that require patient capital — a posture rare among venture-oriented family offices.
