Welcome to the Ring Venture Club

Exclusive to Texas A&M Former Students and Friends

Join Your Fellow Aggies

We are a venture investing club for former students and friends of Texas A&M. Together we evaluate venture deals, share insights and network with one another. Then each member has the opportunity to make an independent investment decision. It’s your portfolio, your decision.

This is a smart, simple way to own an asset class missing from many investors’ portfolios – and there’s no charge to be a member.
