About Us

Knowing the pace and breadth of innovation is increasing, we enable our clients to change with the times with a sense of confidence. We help you see many possibilities, mindful of lessons learned in our years of serial entrepreneurship and venture capital.

What started in 1996 as a boutique venture firm, connected us with amazing entrepreneurs, venture funds, enterprise venture groups and acquisition teams, angels, incubators, universities and family offices. In 2001, we started building a university MBA network to help students learn about venture capital, private equity, due diligence, evaluating companies and pitching new ventures. Today this is known as the G51 Venture Scholars’ program, which has seen more than 350 alumni complete the program.

Starting in 2015, we leveraged our 18 years of VC networks and 14 years of university programming to launch a new research business called G51 Amplify. Today this has transformed into the G51 Studio, where we help our clients strategically scale their startups by connecting interesting and strategic businesses, people, and technology.

Currently, we are not raising a new venture fund but rather leveraging the assets of our combined client base to connect preparation with opportunity. Our partners and extended team continue to participate in direct investing while we continue to review early-stage startups and assisting those that we take a personal interest in by offering feedback, strategic advice, and investment matching, free of charge.

Our inherent goal is to enable human prosperity through the democratization of entrepreneurial education and networks. Our practice of  “Paying-It-Forward” and nurturing our career-long networks help make this possible.
