Anna Harman is the co-founder and CEO of Studs, the New York-based ear-piercing and earrings brand she launched with Lisa Bubbers in November 2019. A former mutual-fund lawyer and Bridgewater Associates operator turned consumer-retail entrepreneur, Harman built Studs to fill the gap between Claire's and the tattoo parlor: a clean, needle-piercing studio paired with curated 'Earscapes' of affordable jewelry. The store was profitable in its first month and has since grown to dozens of locations nationwide, raising a $20M Series B in 2021 and roughly $25.6M in total funding.
George Kalogeropoulos is the co-founder and CEO of HealthSherpa, the private-sector enrollment engine that sits on top of HealthCare.gov. When the federal exchange buckled at its 2013 launch, he and two collaborators built a faster alternative in a matter of days. HealthSherpa has since enrolled more than 10 million Americans in ACA coverage. Raised in Greece by a sculptor father and a tutor mother, he studied political science at Yale, did a stint at Bridgewater Associates, then pivoted a Y Combinator rent-prediction startup into a mission to make health insurance legible.
Andrew Duffy is the co-founder and CEO of SparkPlug, a San Francisco software company that pays frontline retail and restaurant workers cash bonuses for the sales they actually drive. A behavioral-science nerd from Harvard who put in time at Bridgewater Associates and built a luxury whole-leaf tea brand before this, Duffy turned a teenage hot streak selling margaritas into a venture-backed platform that has routed millions of dollars in supplemental income to hourly employees and raised $11.5 million to keep going.
Bob Elliott is the co-founder, CEO and CIO of Unlimited Funds, a New York firm that uses Bayesian machine learning to replicate the returns of hedge funds, venture capital and private equity inside low-cost ETFs. A Harvard-trained botanist turned macro investor, he spent roughly 15 years at Bridgewater Associates, where he sat on the Investment Committee, helped run the flagship Pure Alpha fund, and built and led Ray Dalio's personal research team for nearly a decade. Today he is one of the most-followed independent macro voices on financial Twitter and the manager behind the HFND and HFGM ETFs.
Micah Rodman is the Co-Founder and CEO of Kojo, the leading AI-powered construction procurement platform processing over $5 billion in annual materials orders for 600+ contractors across the US and Canada. A Yale alumnus who cut his teeth as a manager on Ray Dalio's team at Bridgewater Associates, Rodman co-founded Kojo in 2018 to digitize the paper-and-phone world of construction materials procurement. He transitioned from COO to CEO after founding CEO Maria Davidson stepped back, steering the company through a $94M fundraise and partnerships with industry giants like Wesco International.
Jeremy Fraenkel is the CEO and co-founder of Fundamental, the AI lab that emerged from stealth in February 2026 as a $1.4 billion unicorn with $255 million in funding. A DeepMind alumnus with a graduate degree in Machine Learning from UC Berkeley, Fraenkel previously cut his teeth at JPMorgan and Bridgewater Associates before founding and exiting two startups. At Fundamental, he and co-founders Marta Garnelo (Chief Science Officer, ex-DeepMind/Isomorphic Labs) and Gabriel Suissa are building NEXUS, a Large Tabular Model that does for structured enterprise data what LLMs did for language - delivering accurate predictions from raw tables with a single line of code, no preprocessing required.
