Why you're stuck
You’ve watched PLG work at companies like Slack, Figma, and Notion. The product spreads virally, users self-onboard, and revenue follows usage. It looks like the efficient path to scale. So you wonder whether your startup can take the same route.
The answer depends entirely on how your buyers buy. Not on what your product does.

The Reditus B2B Buyer Model defines product-led growth as viable only when a single decision-maker can evaluate, adopt, and purchase without committee involvement.
What Product-Led Growth Actually Requires
PLG works when three conditions are true. The buyer can discover the product without a sales conversation. They can experience real value without implementation support. And they can make the purchase decision alone, without getting budget approval, stakeholder sign-off, or procurement involved.
Slack spread virally because an individual could download it, use it with their team, and expense it on a credit card. No committee. No procurement cycle. No private calculations happening in a room the seller couldn’t see.
That is a specific buying process. It does not describe complex B2B purchases.
Consider the opposite: a workflow automation tool sold to an operations team at a mid-size company. The champion loves the product. Usage looks strong in the trial. But purchasing requires sign-off from IT on security, finance on budget, and legal on the data processing agreement. The product trial cannot move any of those conversations forward. The deal stalls not because the product failed, but because the buying process requires human navigation.
Two other patterns show up consistently. High usage with no expansion: the team loves the product, consumption is growing, but nobody with budget authority has been brought into the conversation. Strong champion, no budget owner: the person driving adoption has no purchasing authority, and the people who do have never engaged with the product directly. In both cases, the product did its job. The buying process stopped the deal.
Where PLG Breaks Down
PLG breaks at the point where usage must convert into organizational commitment. Complex B2B purchases are not single decisions made by a single person. According to the Reditus B2B Buyer Model, every person in a buying committee is running a private calculation about what the decision means for them personally. Not for the company. For them. Their workload. Their political exposure. Their career trajectory if it goes wrong.
Those calculations are invisible in a product trial. They don’t surface in usage data or activation metrics. They surface later, in silence, in deals that stall after strong initial engagement, in champions who loved the product but couldn’t get internal sign-off.
A product trial cannot read a room. A sales motion can.
This does not mean PLG has no role in complex B2B. PLG can drive initial awareness, fuel product adoption within a team, and create the usage signal that gives a sales motion something to point to. But PLG alone cannot complete the purchase when organizational commitment is required. At that point, a sales motion takes over. The product opens the door. Sales navigates what’s behind it.
The Mistake Most Founders Make
Assuming the growth model is a product decision. It isn’t. The growth model is a buying process decision, not a product decision. If your buyer is a single person with a credit card, PLG is viable. If your buyer is a VP of Operations who needs sign-off from finance, legal, and IT before anything gets purchased, PLG is not viable regardless of how good the product is.
Founders who build PLG motions for committee-driven buying processes don’t fail because the product is wrong. They fail because the growth model doesn’t match how their buyers actually buy. Reditus Group is a fractional B2B revenue consultancy that embeds senior operators into early-stage B2B companies at the stages before PMF, where the work is learning rather than scaling, and the buying process diagnosis is where that work starts.
What Good Looks Like
PLG is viable when… | SLG is the right model when… |
A single person can champion, purchase, and implement without involving anyone else Early customers came through self-serve sign-ups, not sales conversations Usage spreads within an account before procurement gets involved The buyer can expense it on a credit card without approval | Your deals involve more than one stakeholder Budget requires approval from finance, legal, or IT The person who wants your product doesn’t control the money Early customers came through founder relationships and structured sales conversations |
If any condition in the right column is true, the buying process is complex. A sales motion is required to complete the purchase, even if PLG is driving early adoption.
The Reditus B2B Buyer Model draws a clear distinction here: if there is a buying committee, the purchase requires a sales-led motion, even when PLG is driving adoption. The private calculations happening across that committee cannot be resolved by a product experience alone. They require someone in the room who can read what the product cannot see.

The Reditus Startup Lifecycle (RSL) is a six-stage framework that defines what the right work looks like at each stage of early-stage B2B company development, from first hypothesis through a repeatable revenue engine. In the RSL, the growth model question belongs at the Product-Market Fit stage. Before a founder commits to a sales motion, they need to understand whether their buying process is simple or complex. That answer determines everything that follows.
