Before becoming a partner at Golden Ventures, Jamie worked in corporate development at Kevin O'Leary's firm, practiced tech M&A law at Osler, and led business development at a company, giving him a mix of dealmaking, legal, and operating experience that's rare for an early-stage investor. He focuses on fintech, energy, and frontier technology like compute, minerals, and quantum computing, and tends to back infrastructure-heavy companies—often looking at how outdated market structures create opportunities, as seen in his early and follow-on investments in Float.
