North America, New York, United States, New York

Description

Addition is a prominent venture capital firm founded in 2020 by Lee Fixel, a former partner at Tiger Global Management. Known for his prolific and rapid investment style, Fixel established Addition with a flexible mandate to invest across various stages, from early-stage startups to mature growth-stage technology companies globally. The firm distinguishes itself through its ability to deploy significant capital quickly, often bypassing traditional venture capital processes in favor of a more direct and efficient approach.

Addition's investment strategy is sector-agnostic within technology, encompassing areas such as enterprise software, fintech, consumer internet, and healthcare tech. The firm is recognized for its founder-friendly approach, offering substantial capital without demanding board seats in every investment, which appeals to entrepreneurs seeking capital with fewer strings attached. This operational flexibility allows Addition to participate in both smaller, strategic early-stage rounds and larger, more competitive growth equity deals.

Since its inception, Addition has rapidly scaled its capital base. Its inaugural fund closed at an impressive $1.3 billion in 2020, followed by subsequent funds that have brought its total capital under management to over $5 billion across four funds. This substantial capital pool enables Addition to write significant checks, with typical first investments ranging from $1 million for early-stage companies to as much as $200 million for growth-stage opportunities. The firm's speed and scale have made it a formidable player in the venture capital landscape, often co-investing with other top-tier firms while also leading rounds.
