Amboy Street Ventures

Amboy Street Ventures is one of the few funds in the United States built explicitly around women’s health and sexual wellness, and the focus is the entire point of the firm. From its Los Angeles base, the firm invests at seed and Series A in companies tackling the trillion-dollar global care gap in women’s health, with portfolio companies including Evvy and Contraline that sit in the diagnostic and contraceptive categories respectively. The work is specialized in a way that matters, because the founders building in this category face a fundraising environment that has historically under-priced their work.

The thesis is women’s and sexual health and consumer wellness, with an emphasis on companies whose products address conditions, life stages, or care models that mainstream healthcare has tended to ignore. AI focus is real where the technology improves diagnostic accuracy or consumer experience, and the firm is comfortable with products that combine clinical credibility with consumer-grade design. Founders working outside the category are typically not a fit; founders inside it should expect a partner who has spent years building a network around it.

Checks fall in the one to five million dollar range, deployed at seed and Series A. The firm participates and often leads or co-leads rounds at the seed stage where its category expertise is most useful, and on the cap table the leverage is a partner whose entire portfolio reinforces the credibility of the category to other investors. Geography is centered on the United States, with Los Angeles as the operating base and a clear willingness to engage with founders across the country.

The firm is small and focused, with a partnership rather than an associate-led process. Founders engage directly with the principals.

The approach is thesis-driven and operationally embedded in the women’s-health ecosystem. The firm is most useful on questions of clinical strategy in categories where the regulatory and reimbursement paths are still being established, brand and trust at the consumer layer, the choice of which payer and employer relationships to court, and the long-term work of educating the broader investor community about why the category deserves the capital. Process is direct, with diligence resolved through working sessions and references. Follow-on participation is part of the firm’s strategy and consistent with its stage focus. For founders building in women’s health and sexual wellness who want a partner whose entire firm is built around the category, the proposition is rare and concrete.
