What a Head of Growth Actually Does

A Head of Growth is a systems architect for revenue, deciding where to place strategic bets, not just a campaign manager. They align product, engineering, and marketing around shared metrics and build the experimentation engine.
Why it exists
Companies need a single owner to connect disparate functions like product, marketing, and sales to drive revenue growth through a systematic, data-driven process. The Head of Growth role was created to be this strategic, cross-functional leader, moving beyond isolated campaigns to build a cohesive growth engine.
The mental model
Think of the Head of Growth as a portfolio manager for growth initiatives. They don't execute every trade (campaign) themselves. Instead, they decide on the overall investment strategy (which channels to focus on), manage the fund (the growth team), and report on performance, ensuring all parts of the business are aligned on increasing the portfolio's value.
How it works
The Head of Growth's work has four core pillars. First, owning the growth strategy by deciding which channels to invest in and which metrics to optimize. Second, managing a team of specialists across acquisition, lifecycle, and product growth. Third, driving cross-functional alignment with product, engineering, and sales. Fourth, building the company's experimentation system—the processes for generating, prioritizing, and learning from dozens of experiments per quarter.
When to use it
This role is crucial when a company needs to build a scalable, repeatable engine for growth, moving beyond siloed marketing efforts. A Head of Growth brings strategic direction, operational rigor through experimentation, and the leadership to connect various teams to a single, shared growth metric. They are systems builders, not just campaign runners.
When not to use it
Don't hire a Head of Growth if you just need a senior marketer to execute campaigns; that's a Growth Marketing Manager. The Head of Growth is strategic and managerial. The role is also distinct from a VP of Marketing, who has a broader remit including brand and communications, or a CMO, who holds C-suite and board-level responsibilities.
One canonical example
A scale-up hires a Head of Growth. Instead of just increasing the ad budget, she analyzes the entire user journey and identifies a major drop-off in activation. She then orchestrates a cross-functional effort: the product team builds a new onboarding flow, the lifecycle team tests a new email sequence, and the data team measures the impact. She isn't running the ads or coding the feature; she's directing the entire system towards a key business outcome.

Why? this is the answer
The card defines the Head of Growth as a "systems architect" who "aligns product, engineering, and marketing" and "builds the experimentation engine" for "scalable, repeatable growth." Option D describes a campaign manager, which the Head of Growth is explicitly stated not to be, as they focus on strategic direction rather than direct execution.
