$170M Founder Yoshi Yokokawa (Alpaca) on 2008 Crash, Diversification Myths, Day Trading and Burnout

Send a text

Yoshi Yokokawa, co-founder and CEO of Alpaca, joins Personable with Harvey Bracken-Smith. Alpaca is a leading brokerage infrastructure and self-clearing fintech powering over 7 million brokerage accounts across 40 countries and backed by more than 170 million dollars in funding.

Before building Alpaca, Yoshi began his career at Lehman Brothers, experiencing the rise and fall of one of the most famous investment banks during the 2008 financial crisis. He went on to become a day trader, founded machine learning startups, and ultimately created Alpaca, a company redefining how global investing is built through APIs.

In this episode, Yoshi shares how he learned from both the boom and the collapse of global markets. He discusses why every generation forgets financial history, why real diversification fails in downturns, and how to stay grounded while raising hundreds of millions of dollars. Yoshi reflects on founder-market fit, emotional resilience, and what it means to build something that gives others financial freedom, the goal he has chased since childhood.

◽️ Why diversification is often a myth in real crises
◽️ Lessons from day trading and "street fighting" in the FX markets
