Nagar Koopersmith Ventures is a newly formed US-based venture capital firm founded by former Pritzker Group investors Sonia Nagar and Adam Koopersmith. The firm was created to back early-stage B2B marketplace companies, drawing on the founders’ experience investing across software-enabled business models and platform-driven companies. The fund reflects a focused, specialist approach rather than a broad multi-sector mandate.
In early 2026, the firm closed its debut venture capital fund at $50 million. The fund is intentionally sized to support hands-on investing at the early stages, allowing the partners to work closely with founders and maintain meaningful ownership positions. The fund is designed to invest primarily at the seed and early Series A stages, targeting companies that are early in commercialization but have validated demand signals and clear paths to scale.
Fund I reflects the founders’ conviction that B2B marketplaces remain underpenetrated relative to consumer platforms, particularly in industries where legacy processes are fragmented or inefficient. While modest in size compared to large multi-stage funds, the vehicle is structured to lead or co-lead early rounds and reserve capital for selective follow-on investments.
Leadership
The firm is led by co-founders Sonia Nagar and Adam Koopersmith, both of whom previously invested at Pritzker Group Venture Capital. Their background includes evaluating and supporting software-driven companies with strong marketplace dynamics, pricing power, and network effects. The partnership combines analytical investing experience with an operator-oriented perspective on scaling early platforms.
Investment Strategy
The fund follows a concentrated, thesis-driven strategy focused on early conviction. The partners look for founders with deep domain expertise building marketplaces that solve real operational pain points for businesses. Investment decisions emphasize market structure, liquidity dynamics, and defensibility, rather than purely top-line growth. The firm aims to be an active partner on strategy, early customer acquisition, and business model design.
Notable Investments
As a newly raised fund, the firm has not yet publicly disclosed portfolio investments from Fund I.
Notable Exits
The fund has not yet recorded exits, given its recent launch.
Other
This firm is particularly relevant for founders building B2B marketplaces who want a focused early-stage partner rather than a generalist fund. Founders should expect a high bar around marketplace mechanics, unit economics, and long-term defensibility. Given the fund’s size and early-stage orientation, it is best suited for companies seeking engaged lead investors rather than large syndicates.
