Here's what I don't understand: if you're a crypto project, why wouldn't you raise funds through an ICO yourself? What benefit does a16z give you? One of the biggest assets of crypto is the ability to self-fund. Also, since the space is relatively new, I have my doubts about the ability of a16z to provide any useful crypto experience.
Beyond the legitimacy of being backed by a well-known venture capital firm, the most obvious is from the article:
"We provide operational support to entrepreneurs. Our crypto investments have access to the same 80+ person a16z operating teams as do our non-crypto investments. Our operating teams have deep expertise in executive and technical recruiting, regulatory affairs, communications and marketing, and general startup management. We are responsible participants in the governance of companies and the governance of networks."
