The Goldman Banker Who Built a Different Kind of Cap Table

In the 1980s, when Deborah Jackson went out for client dinners as a Goldman Sachs investment banker, she was often the only woman at the table. She spent two decades raising capital for early-stage healthcare and technology companies, watching from the inside how money finds some founders and skips others. Then she left - and set out to rebuild the table itself.

The firm she built, Plum Alley, is a New York early-stage venture operation with one deceptively simple rule: it backs frontier-technology and medical-breakthrough companies that have at least one woman on the founding team. It is not a charity and it is not a soft "women's fund." It is a bet that the market has been mispricing an entire category of founders - the scientists and engineers who happen to be women - and that closing that gap is where the returns hide.

Since its first venture check in 2017, Plum Alley reports deploying more than $100 million across roughly three dozen companies, in fields ranging from CRISPR gene editing to autonomous freight to the sensors that read a city's wastewater.

01 / THE THESISBacking the scientist who happens to be a woman

Plum Alley's underwriting starts with the founder. The firm looks for domain experts - PhDs, MDs, technologists with real depth in a hard problem - and requires that at least one of them be a woman. From there, the sectors read like a map of the next decade: biotech and precision medicine, climate and environmental monitoring, robotics and automation, autonomous vehicles, agriculture and the future of food, and artificial intelligence.

The stage matters too. The firm concentrates on the point where women founders have historically fallen off a cliff - the Series A, where the science is largely proven but the market is still skeptical. That is where Plum Alley aims, and its co-founder Andrea Turner Moffitt has framed the mission plainly.

"We want to push a bigger conversation around the scientists and the technologists who happen to be women." Andrea Turner Moffitt, Co-Founder

02 / THE PORTFOLIOWhat $100 million actually bought

The clearest way to understand the firm is to read its portfolio. There is no single sector holding it together - only the founder mandate and a preference for companies solving genuinely hard problems. A few names give the shape of it:

Mammoth Biosciences, the CRISPR company, went on to reach unicorn status. Biobot Analytics became one of the reference points for reading COVID trends through a city's sewage. Einride builds electric, autonomous freight. The through-line is not a category - it is a type of founder, and a type of problem the rest of the market found too early, too technical, or too easy to overlook.

Figures are approximate, drawn from the firm's own reporting. Portfolio companies raised roughly $725M in follow-on capital in 2021 alone.

03 / THE MODELWhen the members write the checks

The most distinctive thing about Plum Alley is not what it invests in - it is who does the investing. The firm runs a membership community of accredited investors who pay annual dues, roughly $2,500 to $5,000, for curated access to vetted deals, salon-style events and private dinners. Members then choose which deals to back, one at a time, through special purpose vehicles, assembling their own portfolios alongside the firm's funds.

Layered on top of that community are the institutional vehicles: Plum Alley Ventures Fund I, a roughly $25 million fund with the Consumer Technology Association as an anchor investor, and, since 2024, Plum Alley Ventures Company - an umbrella designed to scale the model through domain-expert managers running sector- and stage-specific funds. In 2026 the firm is adding an AI-focused vehicle, Foresight AI Fund II.

Roughly three-quarters of the members are women, which is unusual in an asset class where women have long been a small minority of investors. That is the second half of Jackson's mission - not just funding overlooked founders, but pulling overlooked investors into the room. Her explanation for why the community had to be built this way has become the firm's defining idea.

"Women invest only when head, heart and soul align. We see investing as a way of shaping the future." Deborah Jackson, Founder & CEO

04 / THE FOUNDERA career disrupted on purpose

Jackson's path is a three-act reinvention. First, two decades on Wall Street, much of it at Goldman Sachs, raising capital for early-stage healthcare and technology companies. Then a boutique financial-services firm of her own, followed by a turn as a tech entrepreneur - she helped launch one of the first mobile-first accelerators for female-led startups and organized what she describes as one of the first all-women hackathons. Now she runs a venture firm.

She describes herself as a builder of institutions for people historically excluded from capital flows, and she is candid about the model she is borrowing from: the way earlier outsiders on Wall Street built their own firms when the established ones would not have them. That framing runs all the way down to the name. "Plum Alley" was the historic Chinatown of Salt Lake City - a dense immigrant community of laundries, groceries and restaurants, built by people locked out of mainstream capital, and demolished for a parking lot in 1952.

"We believe that venture capital is one of the best ways to have influence and impact in the world." Deborah Jackson

The recognition has followed. Jackson was named to the Forbes 50 Over 50 list for investing in 2021, and the firm's work has been covered by Forbes, Fortune, Inc. and The Information. But the more telling signal may be the follow-on money: capital does not chase a diversity story, and Plum Alley's portfolio companies have repeatedly raised larger rounds at higher valuations from mainstream investors after the firm's early bet.

05 / THE MARKETWhere Plum Alley fits

Plum Alley sits at the intersection of two crowded lanes and belongs cleanly to neither. It is not just a gender-lens fund like Female Founders Fund or BBG Ventures, because its center of gravity is hard science and frontier engineering, not consumer or software. And it is not a generic syndicate platform like AngelList, because its deals are curated around a specific thesis and community. The combination - a membership community, an institutional fund, and deal-by-deal SPVs, all pointed at women-led deep tech - is the moat.

The firm also ties its portfolio to impact explicitly, aligning its companies with ten of the United Nations Sustainable Development Goals. For members, the pitch is unusually concrete: you are not handing money to a black-box fund, you are learning to invest in frontier technology one deal at a time, in a room full of people doing the same thing. For founders, it is early conviction capital from investors who can read a scientific data room.

What began in 2011 as a curated crowdfunding site has become a multi-fund venture company, still built around the same conviction that started it: the next great companies come from founders the rest of the market has been trained to overlook, and the capital to back them can come from investors who were overlooked too.
