Growth vs. Marketing vs. Product

Rough division: brand work lives in Marketing. Growth marketing (paid, SEO, email) can live in either. Growth product work (NUX, notifications, viral features) typically lives in Growth.

The cleanest distinction: product teams create core value and deepen product-market fit. Growth teams deliver that core value to more people.

Ownership runs on a spectrum. 'Growth-as-a-service' teams own no code and act like internal consultants: lightweight, but scattered. Autonomous teams fully own NUX, notifications, adtech, the A/B platform, payment flows: deep ownership, but they need real staffing.
