I'm a solo cofounder who has been a growth lead for 3 software startups in Southern CA. I've helped each of those companies reach 7 to 10 digit ARR — including one YC company form the 2014 Summer batch. I say solo cofounder because while I'm technical, I'm not a ERC20 developer. I'm trying to "hire my cofounder" as Mark Suster would say.
