How PLG Changes the Revenue Model
- Product-led growth lets users adopt and expand on their own, so revenue arrives in many small self-serve transactions.
- The funnel starts with a free or trial motion, which means acquisition cost and conversion behave differently than in sales-led models.
- Revenue is lumpier and more usage-driven, so finance needs near real-time visibility into product activity.
- The CFO's job shifts toward understanding activation, conversion, and expansion loops inside the product itself.
