What is product-led growth (PLG)?
Product-led growth (PLG) is a go-to-market strategy in which the product itself is the primary driver of customer acquisition, conversion, and expansion — rather than a sales or marketing team. Users typically start through a free trial or freemium tier, experience value on their own, and convert to paid without ever speaking to a rep. The term was coined by the venture firm OpenView in 2016. PLG brings a consumer-like, self-serve journey into B2B software, letting the product do the selling and reserving human touch for where it adds the most value.
Product-led growth flipped a basic assumption of B2B software: that a buyer commits first and uses the product second. In PLG, they use it first — for free, on their own — and the experience of getting value is what drives the purchase. The product becomes the top of the funnel, the demo, and often the closer.
What “the product drives growth” actually means
In a sales-led motion, people are the growth engine — reps source and pitch, and buyers usually commit before they’ve meaningfully used the thing. Product-led growth inverts that. Users enter through a free trial or freemium tier, reach an “aha moment” of value themselves, and convert to paid on the strength of that experience. OpenView, the firm that coined the term in 2016, framed it as bringing a consumer-like, self-serve journey into enterprise software — de-laboring the growth engine so the product does the work that reps used to.
PLG doesn’t mean “no sales”
The common misread is that PLG eliminates sales. It doesn’t; it changes what sales does. As OpenView’s Blake Bartlett has described, the mature version is product-led sales — reps stop cold-sourcing demand and instead engage accounts already active in the product, focusing on expanding the ones showing real usage. The motion runs on evidence: instead of a rep guessing who’s interested, the product tells them who’s engaged, and sales moves those accounts up-market. A marketing qualified lead in a PLG world is often a product-qualified one — defined by what a user did, not what they downloaded.
Where signals come in
PLG’s native signals are usage — activation, feature adoption, seat growth, brushing against a usage limit. Powerful, but incomplete: usage tells you an account is engaged, not whether something just changed that justifies a bigger conversation. Layering external buying signals on top closes that gap. When a highly-active free account also just raised funding or expanded a team, that’s the moment for product-led sales to reach out about expansion — and to open with the specific change rather than a generic “noticed you’ve been using us a lot.” Trayo supplies that external layer, detecting the events around your active accounts and drafting the timely touch.

Frequently asked questions
What is the difference between product-led and sales-led growth?
In sales-led growth, people — reps and marketers — are the primary drivers of acquisition and expansion, and buyers usually commit before they use the product. In product-led growth, the product drives those things: users self-serve through a free trial or freemium tier, experience value first, and buy after. Sales-led leads with a conversation; product-led leads with the product.
What are freemium and free trials in PLG?
They're the two most common entry motions. Freemium offers a permanently free tier with limited features or usage, betting that some users upgrade as their needs grow. A free trial offers full or near-full access for a limited time. Both let a prospect reach an 'aha moment' of value on their own before any purchase decision — the mechanism PLG depends on.
Does product-led growth mean no sales team?
No. Most successful PLG companies still have sales, but the motion is inverted: instead of sales finding and pitching cold prospects, sales engages users and accounts that are already active in the product. This is often called product-led sales — reps focus on expanding accounts showing strong usage signals rather than sourcing demand from scratch.
How do buying signals apply to a PLG motion?
In PLG, the richest signals are product usage — activation, feature adoption, seat growth, hitting usage limits. Layering external signals like funding, hiring, or leadership changes on top tells a product-led sales team which self-serve accounts are both engaged and undergoing a change that justifies an expansion conversation. Signals turn usage data into a prioritized list of who to reach and when.
