Armina "Arms" Rosenberg built an AI that reads 30,000 articles a week so her fund doesn't have to rely on luck, and a human still makes the final call on every trade.Armina is co-founder and portfolio manager of Minotaur Capital, an AI-led global equities fund she started with Thomas Rice, the rare fund manager who can also code (he built their AI system, Taurient). Before Minotaur, Armina spent eight years in sell-side research at JP Morgan and ran the global equities portfolio for Atlassian co-founder Mike Cannon-Brookes' family office, Grok Ventures.This one is a proper look inside a business that has put AI into every step of its process, with experienced investors shaping the system rather than handing it the keys.About the guest:Armina "Arms" Rosenberg, Co-founder and Portfolio Manager, Minotaur Capital minotaurcapital.comAbout the show:Experts in the Loop is a podcast about how real experts put AI to work.
