A three-tier map founders are expected to construct and disclose before and during hiring a head of product, resolving which parts of the product each side owns:
Ownership ambiguity between the founder and the new product leader — never mapped explicitly, or mapped but not disclosed to the candidate — is named as a root cause of the role's characteristically short tenure. See Head-of-Product Hiring Failure Base Rate for the base-rate framing this map is meant to counteract.
Related to Product Leader vs. PM Leader (Vocabulary Split): the map is only meaningful once it's clear which of the two roles is actually being hired for.
Before finalizing a product-leader hire, the founder/CEO should write down, concretely, which parts of the product they intend to keep owning after the hire — and pair that with an honest self-assessment of whether they are personally strong at strategy before deciding to delegate it. This exercise is meant to happen pre-hire and to be shared transparently with candidates during interviews, rather than surfacing as a surprise after the person joins.
Ownership is communicated to candidates across three tiers, not a binary owned/not-owned split: (1) aspects the candidate owns entirely, (2) aspects the candidate owns but where the founder wants to be consulted, and (3) aspects the founder primarily owns while still expecting the candidate's input. Laying out this three-tier map explicitly during interviews preempts later friction over decision rights and lets a candidate self-select out before joining if the arrangement doesn't work for them.
A related unstated assumption the source calls out: hiring a head of product does not mean the founder 'washes their hands' of the product entirely. Much of the role's documented short tenure (see Head-of-Product Hiring Failure Base Rate) traces back to this assumption being left implicit instead of made explicit through the three-tier disclosure.
Golubovski calibrates the founder/product-leader split by company stage: in an early-stage startup, the founder/CEO drives product vision directly and product leadership's job is mainly to support that vision. As the company matures past founder-led product, the product leader takes on responsibilities that used to sit with the founder — market and competitive understanding, portfolio expansion, and market entry decisions.
See Product Stage as the Primary Fit Factor for Product Leadership for the related question of which leadership archetype fits which stage.

This is a concrete elaboration of the ownership-mapping problem this page already covers, specific to founder-led, single-product companies like Whatnot.
