Keiretsu Forum is a global investment community of accredited private equity angel investors, venture capitalists, and corporate/institutional investors. Founded in 2000, it is the world's largest and most active angel investor network, with numerous chapters across North America, Europe, and Asia. Keiretsu Forum members provide early-stage capital and resources to high-quality, diverse investment opportunities. The forum facilitates a collaborative due diligence process and provides a platform for entrepreneurs to present their ventures to a discerning investor audience. Beyond funding, Keiretsu Forum emphasizes mentorship and strategic partnerships to foster growth in its portfolio companies.
Serves as the global administrative and support center for the Keiretsu Forum network, coordinating activities across its international chapters, managing global memberships, and organizing global events.
The headquarters is primarily an administrative office focused on global network management rather than a large physical campus. Its key feature is its role as the central node in a distributed global network.
The work culture at Keiretsu Forum's central office is likely collaborative, fast-paced, and focused on supporting entrepreneurs and investors. It emphasizes professionalism, diligence, and fostering connections within the global investment community.
The San Ramon headquarters is significant as the operational core of the world's largest angel investor network, facilitating the flow of capital and expertise to startups globally.
Keiretsu Forum operates globally through a vast network of over 50 chapters across North America, Europe, Asia, and Australia. This decentralized structure allows it to support local entrepreneurial ecosystems by connecting local startups with accredited angel investors. Functions supported globally include deal screening, due diligence collaboration, investor education, entrepreneur presentation forums, and multi-chapter investment syndication. Keiretsu Capital, its exclusive global fund partner, further extends its reach by co-investing with members.
