What does the founder keep — permanently?

The transition is not abdication, and framing it that way is why founders resist it. Three things stay founder-owned indefinitely: vision — the ten-year view of where the product goes, which no hire replaces; bet-level decisions — new market entry, platform shifts, the calls that could kill the company; and taste veto — the right to say "this isn't us" on the rare thing that violates the product's character. Written down, this list is short. Unwritten, it silently expands to everything — which is failure mode #1.

What transfers — and in what order?

Over 90 days, in sequence. Days 1–30, observation and context: the new leader (hired, promoted, or fractional) absorbs the strategy, meets the customers, sits in the decisions — while the founder still decides. Days 31–60, shared decisions: the leader runs prioritization and discovery with the founder in the room but explicitly not in the chair; disagreements get resolved by the written framework, not by rank — this month is where the transition actually happens or doesn't. Days 61–90, transferred decisions: roadmap, prioritization, team leadership, and day-to-day customer strategy sit with the leader; the founder engages through a weekly strategy session and the written keep-list, not through the backlog.

What are the failure modes?

Four, in order of frequency. Shadow ownership: the founder attends "just to listen," the team reads the room, and every decision routes around the new leader within weeks — the fix is physical absence from execution forums, not silence within them. Boomerang decisions: the founder overrides one call in week six; the team learns the override channel exists; the structure dies quietly — overrides must go through the written framework or not at all. The empty keep-list: founders who transfer everything including vision disengage entirely, and the product loses its soul along with its bottleneck. And transferring to a vacuum: handing decisions to a PM who lacks the seniority to hold them against the sales VP — decision rights require decision weight; that's the CPO-vs-VP question, answered before the transition starts.

Who should the transition transfer TO?

Three structures, matched to stage in the first-product-leader guide: a promoted senior PM (works when strategy is settled and the person has range), a hired head of product (works past the org size where the seat fills), or fractional leadership first. I'll make the case for the third plainly, with the disclosure that it's what I sell: a fractional CPO is structurally well-suited to transitions specifically because the engagement is designed to end — the incentive is building a structure that runs without them, then handing it to the permanent owner. In my engagements the transition arc above IS the 90-day plan, and the founder's keep-list is written in week one.

Transfer the decisions, not just the meetings. The team can tell the difference in about a week.
