The board of directors for a private company is generally secret in the US. Only the "manager" aka president/CEO/whoever at the top is generally named publicly, as well as legal agent.
Not really that easily? Generally, only the legal agent for the private company will know and the direct hires of the board i.e. the CEO/CTO/whoever they name up top. Sometimes board of directors can get named in court records but with the public records redacted. But outside of that? Not even the IRS knows unless the directors get compensation.
