Hipster didn't start the company alone. He co-founded it with two local partners and owns 20 percent. They do strategy; he does operations, which means he's the one who can log into the company bank account and move money: vendors, subscriptions, payroll. The account never held more than the equivalent of $30,000, and none of it ever felt like his.
That instinct is right about ownership and wrong about the FBAR. Ownership and control are separate triggers, and Hipster has one of them.
Ownership. Under 31 CFR § 1010.350(e)(2)(ii), a US person has a financial interest in an entity's account through ownership only by owning, directly or indirectly, more than 50 percent of a corporation's voting power or total value (or of a partnership's profits or capital). At 20 percent, no.
Control. Signature or other authority (31 CFR § 1010.350(f)(1)) is the authority, alone or together with another, to control the disposition of money or other assets in the account by direct communication with the bank. If Hipster can wire money out, he has it, whether or not a dollar is his.
There's an exemption in § 1010.350(f)(2) for certain officers and employees of banks and other regulated entities. It's built for a bank's own staff, not a startup's operations lead. Sorry, Hipster.
