A more effective mental model than PLG vs. SLG is analyzing which activities create new demand versus which ones harvest existing demand. Both sales and product can serve either function. Creating demand is always the harder, more critical challenge for any revenue engine.

In the pre-product-market fit stage (the first ~20 deals), the sales leader's primary role is not just closing revenue, but acting as a product manager. They must be in every meeting to gather objections, find pockets of value, and translate raw market feedback into actionable insights for the engineering team.

The "build it and they will come" mindset is a trap. Founders should treat marketing and brand-building not as a later-stage activity to be "turned on," but as a core muscle to be developed in parallel with the product from day one.

Effective demand generation is a barbell, requiring strong top-of-funnel brand investment to create awareness and great bottom-of-funnel product marketing to convert interest. Viewing performance marketing as a standalone function and funding it in isolation is like "throwing money at a problem but not solving it."

Before hiring for a critical function like growth marketing, Gamma's CEO spent 6-12 months doing the job himself. This immersion taught him what "great" looks like, preventing a bad hire and ensuring he could properly lead the function he was delegating.

A pre-product CRO conducts thousands of market conversations to validate demand and guide the product roadmap. This de-risks development by ensuring you build a product that customers will actually buy, a task more suited to a sales expert than a founder.
