Alumni Ventures co-invests in startup rounds alongside an established lead investor. Its principal focus is pre-seed through Series B, with typical investments of $1 million to $3 million.
The firm generally joins on the lead investor’s terms, does not take a board seat and commits after a lead is secured. Founders do not need an alumni connection to qualify. This makes it a potential syndicate participant for a company that already has the core terms and leadership of its round in place.
Its platform team works on introductions to customers, hires and subsequent investors. Founders can request help through their investment team or the AVP Hub, including access to the firm’s alumni networks and commercial resources.
