“Keiretsu” Definition

Keiretsu is a Japanese term describing a group of affiliated corporations with broad power and reach. Keiretsu Forum is described as a conglomeration of individuals or small companies that are organized around private equity funding for mutual benefit. Keiretsu Forum believes that through a holistic approach that includes interlocking relationships with partners and key resources, they can offer an association that produces the highest quality deal-flow and investment opportunities.

Keiretsu Forum Midwest

The region is a diverse and thriving business ecosystem. With one of the lowest costs of doing business and living in the U.S., it is home to some of the most vibrant Fortune® 500 companies, who actively support tech and innovation growth. With the support of corporations and regional economic development engines, the Midwest is fast attracting a vibrant start-up scene and becoming an epicenter for innovation and investment.

This is aided by an affordable cost of living, world class universities and research centers, and some of the best hospitals in the world. The recent announcement of the smart cities award to the City of Columbus was followed by significant private sector investment. The growth of medical start-ups in Ann Arbor; the establishment of Chicago as a pivotal center for financial innovation; the establishment of Cincinnati as a world class destination for branding, marketing and consumer goods and the rebirth of Detroit as a vibrant tech center, are all contributing to the early successes at Keiretsu Forum Midwest.

Monthly Forum

The “Forum” is a monthly event for Keiretsu Forum. On any given day we spend our time working with and coaching our members as well as focusing on attracting new members who love the ecosystem as much as we do.

We also spend our time strengthening our relationships in the start-up ecosystem and vetting new companies to present to our members. Each month this vetting process involves personal interviews, prescreening interviews and deal screening. We take our start-ups through a rigorous process before we introduce them to the Forum. By the time they are invited to the Forum, we have spent considerable time and energy in cultivating them to present to our members. Our Forums are unique, inviting and very exciting events. These events are strictly by invitation only. If you are interested in attending one of our Forums, please send an email to:


Our Forum typically takes place from 3 – 6 PM followed by cocktails. This provides our members, entrepreneurs and guests with a workable and enjoyable calendar day.
