Bay Partners is a Silicon Valley-based early stage venture capital firm that has been building successful technology companies since 1976, and has funded more than 350 startups. Bay invests in early stage companies either through the seed track ($250K-$750K) in bold out-of-the-box capital-efficient ideas or through the more typical early stage track ($1M-$7M) in early product development stages of companies.

Our main investment themes are consumer services, software as a service, enterprise software, hardware, and energy. Within clean technology we have made investments in Enphase Energy (efficient conversion), Envia (storage), Advanced Power (efficient fossil fuel-based production), and Nanogram (new materials/storage).
