Decision map
The hire is the visible decision. The hidden decision is what you are willing to be wrong about.
Hiring is the part the founder negotiated. The compensation, the start date, the title, the offer call. The decision underneath the hire is harder. It is the decision about what the founder is willing to be wrong about while someone else fixes it. Until that one is made, the seat is staffed but the work has not moved. The senior hire sits in the chair. The founder sits in the call. The org chart and the calendar disagree, and the calendar wins.
Three good hires later, the founder has paid the price of senior people without buying the structural change. The hires were the receipt. The decision was never signed.
