Bio
Professional summary
Lee Fixel is the Founder and Managing Partner of Addition. The provided source is Addition's SEC Form ADV record, which is useful for firm verification but not for a narrative biography. A Washington University profile identifies Fixel as Founder and Managing Partner of Addition and says the firm invests in founder-led, technology-enabled companies. It also notes his prior role as Partner at Tiger Global Management, where he headed the firm's private equity business, and his B.S. in business administration, finance, and accounting from Washington University in St. Louis. Public sources associate his earlier investment track record with companies such as Flipkart, Spotify, Peloton, Stripe, and Facebook, but those are supplemental and should be treated separately from the official ADV source.
