Product Led Growth changed how software gets sold. It turned the product into the way users find, try, and adopt a tool. For a self-serve business, that was a real shift, and it still works.
But most B2B SaaS companies are not pure self-serve. They are sales-led or hybrid. They sell to enterprises, run pilots, and close deals with people in the room. For those companies, the question PLG answers is not the hard one.
PLG asks whether the product can acquire and activate users. Product Led Revenue asks a wider question. How much of the whole revenue motion should the product perform, across conversion, expansion, and retention, and not just the start?
That is the difference. One is a motion. The other is an architecture.
Product Led Growth got a lot right. It proved the product can carry acquisition and activation. It showed that a good first experience sells better than a demo. For companies with a real self-serve motion, that changed the economics of growth. None of that goes away.
The limit shows up after the start. For a sales-led company, self-serve is often treated as a gate. No free trial, no PLG. So the whole conversation stops before it reaches the revenue gaps that matter most. Expansion still waits for CS to notice. Conversion still waits for a rep to act. The roadmap still drifts away from NRR and gross margin. PLG does not speak to any of that, because it was built for the front of the funnel.
This is where people assume Product Led Revenue is just PLG relabeled. The assumption is wrong. PLR does not require a free trial, a freemium tier, or a self-serve upgrade path. A company with none of those is still a valid starting point. That zero state is the baseline, not a failure.
Product Led Growth helps users start. Product Led Revenue helps revenue scale. A company can run both, and many should. But running PLG at the front does not close the gaps in the middle and the end, where most sales-led companies lose the most ground.
The two questions make the split clear. PLG asks whether the product can acquire and activate users. PLR asks how much of the full revenue motion the product performs by design. If your company has outgrown the self-serve debate, the second question is the one worth answering.
No. PLG is a motion for acquiring and activating users. PLR is an architecture for how much of the full revenue motion the product performs, including conversion, expansion, and retention. It applies with or without a self-serve motion.
No. A company with no trial, no freemium, and no self-serve upgrade path is a valid starting point. That is the baseline, not a disqualifier.
Probably yes. PLG covers the start. If expansion still waits for CS to notice and conversion still waits for a rep to act, the revenue gaps PLR addresses are still open.
Seven questions. Five minutes. A pattern read on the spot, no call to see it.
