About Peter Diamandis
Peter Diamandis is the founder and executive chairman of the XPRIZE Foundation. He is also a co-founder of Singularity University and the curator of the Abundance360 community. His own site says he has founded and co-led companies in space, health and AI, and a 2025 profile counts over 25 companies.
He is co-founder and chairman of Fountain Life, a longevity and preventive health company. He has degrees in molecular genetics and aerospace engineering from MIT and an MD from Harvard Medical School. Fortune named him one of the World's 50 Greatest Leaders in 2014. He has written books including Abundance and BOLD, and hosts the Moonshots Podcast, which covers AI and other exponential technologies.
Diamandis invests personally and through venture funds. PitchBook lists him as an active angel investor with 34 recorded investments, while Crunchbase shows a smaller set of 7, so public databases are incomplete. He co-founded BOLD Capital Partners, an early-stage fund covering life sciences, healthcare and frontier tech. His site describes a longevity fund with $600M+ in assets under management. His investment and advisory portfolio on diamandis.com includes Fountain Life, Viome, Anduril, xAI, WHOOP and Retro Biosciences.
In a February 2024 post titled "How to Invest in AI", Diamandis wrote that he had invested in private AI companies personally and through BOLD Capital. He suggested that people interested in angel investing in AI attend accelerator demo days such as Y Combinator's, and talk to graduate students at Stanford and MIT. He also co-founded Link XPV, a venture fund focused on AI. His site describes it as backing AI and exponential startups from MIT and Harvard, with $1B+ in assets under management. His portfolio page lists AI-related names including xAI, Applied AI, Haut AI and Intelligent Internet. Crunchbase records an angel round in Fellow AI with no public date.
Public sources point to early-stage companies in AI, longevity and health, space and other exponential technologies. Tracxn lists his recorded investments as United States-based, mainly in high tech and life sciences. Diamandis has not published a check size or a formal investment thesis for his angel investing, so none is stated here. He has said he looks for AI founders through accelerators and top university programs.
