Lee FixelΒ· Founder & Managing Partner

Lee Fixel ran Tiger Global's private investing business for 13 years, where he championed Flipkart, Peloton, and a generation of Indian startups, before founding Addition in 2020. The New York firm raised more than $5 billion across its first four funds to back early and growth-stage companies, while Fixel kept his famously low public profile.
