Canonical: https://octum.ai/research/managers/addition.html ## The question Who is Addition: what funds has it raised and closed, what does it invest in, who runs it, what has its portfolio returned, and how do the firm and the press describe it? ## GAR's answer Addition primarily backs growth-stage companies with market traction and scalability, devoting resources to support follow-on investments and efficient scaling. ## What we found ### The funds Addition has raised a fifth fund with a size of $1.5 billion. This figure is reported by startupintros.com and techcrunch.com. The firm’s previous funds totaled $1.3 billion, according to techcrunch.com. As of 2023, deadlinedisclosures.com also lists the fifth fund at $1.5 billion. The total assets under management for Addition stand at $6.5 billion, as noted by techcrunch.com. These figures reflect the firm’s growth in capital raised across its fund series. [1] [2] [3] ### The firm Addition is a firm that primarily backs growth-stage companies.

[9] [10] ## Where the sources disagree - The founding year is listed as 2020 by both available sources, but this figure is not independently verified by a primary source or data publisher, meaning an LP cannot confirm the manager's actual start date from these records. [4] [6] - The reported fund size of $1.3 billion is repeated across two non-primary hosts without independent verification, so an LP should treat this capital figure as unconfirmed rather than a verified asset base. [1] [3] - **Portfolio outcomes.** Asked, and the search found no public statement either way. - **The people.** Asked, and the search found no public statement either way. ## Analysis The founding year is not independently verified, as the only available data points are identical self-reported figures from the same source. This means you cannot rely on external corroboration to confirm the firm's actual age or track record length. [4] ## Pros and cons for an LP weighing a commitment to this manager **Pros** - The firm’s fifth fund reached $1.5 billion, indicating strong investor confidence and a larger capital base to support portfolio companies. [1] [2] [3] - Addition’s total assets under management stand at $6.5 billion, reflecting a substantial scale that can provide stability and resources for long-term value creation. [3] - The firm’s strategic focus on growth-stage companies with proven market traction and scalability suggests a disciplined approach to selecting investments with clear paths to expansion. [7] - Addition’s investment thesis targets founders with a proven track record and companies addressing large market opportunities with defensible business models, which may reduce execution risk for investors. [7] **Cons** - The firm’s total assets under management of $6.5 billion are heavily concentrated in its most recent fund, which accounts for $1.5 billion, indicating significant reliance on a single vintage for scale. [3] - The strategy focuses exclusively on growth-stage companies with proven traction, which excludes early-stage opportunities and concentrates risk in later-stage valuations that may be less resilient to market downturns. [7] - The investment thesis targets founders with a proven track record and defensible business models, a criteria set that may limit the pool of investable companies and increase competition for a narrow set of high-quality assets.
