Product Management S-Curve
The product management S-curve is Singhal’s phase model for when product management becomes useful: founders own pre-product-market-fit experimentation, PMs add process after pull emerges, product leaders scale and expand during hypergrowth, and late-stage teams restart zero-to-one work against innovator’s dilemma.
Key points
- Before product-market fit, Singhal argues product management usually does not make sense because the founder is still experimenting rapidly to discover real customer pull [src-052].
- After product-market fit, experimentation must give way to resilience, consistency, predictability, and coordination across teams, which is where product management historically enters [src-052].
- During hypergrowth, product management and chief product officers help scale the existing hit product and expand into adjacent products while the founder works on fundraising, go-to-market, and company scaling [src-052].
- In late-stage big tech, product leadership must combat innovator’s dilemma by creating new zero-to-one products despite the gravitational pull of existing large businesses [src-052].
- The model explains why one product-management job title can describe very different work depending on company stage [src-052].
