The founder's personal exchange account is a diligence problem
It happens the same way every time. A customer pays in USDC, or an investor sends part of a SAFE on-chain, or the team decides to hold a treasury position — and there is no company account for it, so it lands in a founder's personal exchange login. It works fine until the next round, when a data room asks who owns the company's digital assets and the honest answer is a person, not the company.
Fixing it later is worse than setting it up right. Commingled assets create tax questions, cap-table questions, and a diligence thread nobody wants open during a raise. An account titled to the entity, with statements and settlement in the entity's name, closes that thread before it opens.
