Series B

Series BSeries BSeries B is the scaling round, raised on proven unit economics, the stage where marketing must graduate from working channels to a forecastable growth engine with executive leadership. capital buys scale, which means marketing is no longer judged on finding what works but on forecasting it: pipeline models the board can trust, CAC that holds as spend grows, and a team structure beyond a few generalists.

The leadership question becomes acute here. The scrappy approaches that earned the round often plateau under bigger budgets, and the company typically needs its first true marketing executive, full-time or fractional, to build the operating system: planning cadence, channel ownership, and revenue-aligned reporting.

The marker of a Series-B-ready marketing function is boring predictability: if you add a dollar of spend, you can say with confidence what pipeline it returns and when.
