Will crowdfunding disrupt the Venture Capital investing model in the US?

In short, no.  Evidence globally shows that crowdfunding exists alongside other traditional forms of capital formation. Crowdfund Investing can supplement or replace the friends and family/seed round (RegCF), act as Seed/Seed+/Angel Round (RegCF or Title II), or even replace a public offering under $50mm (Regulation A+). However, for firms that are in the limited range of venture interest - easily scalable, TAM of at least $500mm/year, the ability of a Venture Firm to bring rapid additional cycles of financing will often require firms to continue using VCs.
