Colleen Foster is a former Goldman Sachs Partner who led the firm's $1B+ global commodities business before becoming a venture capital investor at Amboy Street Ventures, where she focuses on women's and sexual health companies while serving in leadership roles at Planned Parenthood Federation of America and Planned Parenthood Action Fund. She brings a public-markets risk mindset to early-stage women's health investing and frames the space as a structurally mispriced asset class with trillion-dollar market opportunities, while her GP role at Amboy Street is weighted toward building ecosystem and commercial bridges rather than just underwriting deals.
