About Astor
Astor is a personal investing agent for serious investors. Founded by Bruno Koba (Nubank, monashees) and Daniel Tulha (Stripe, Robinhood), Astor gives every active investor an AI investment advisor working around the clock to surface their next great investment. We’re backed by YC (S25). Retail investors now account for 25% of all U.S. trading volume, nearly double from 2012. But over 56% still say they don’t feel confident in their investment decisions. Astor fixes that. Our AI agents uncover opportunities, decode emerging trends, and deliver analysis tailored to you. Instead of drowning in noise, investors gain a clear edge, shifting from guesswork to confident decision-making.
