General Catalyst backs companies from formation and seed through growth, and also creates businesses with founders through its Creation strategy.
Creation includes starting companies in complex or emerging industries, helping experienced founders launch again and combining existing service businesses with applied AI. That makes GC relevant both to founders raising for an established startup and to entrepreneurs developing a new company with an investment partner.
For businesses that have reached product-market fit, its Customer Value Fund provides a separate way to finance customer acquisition. This sits alongside seed and growth equity, giving the firm a financing model directed specifically at the cost of expanding a customer base.
