Zero Stage Capital

Zero Stage Capital was a venture capital firm based in Cambridge, Massachusetts, that specialized in early-stage investments within the technology and life sciences sectors. Founded in 1981 by Paul Kelley, the firm was a pioneer in the New England venture capital community, focusing on seed and first-stage financing for innovative startups. Its investment portfolio historically included a significant number of companies in biotechnology, medical devices, and healthcare services.
