Product-led growth (PLG) is a go-to-market strategy where the product itself is the primary driver of customer acquisition, expansion, and retention. Instead of relying on sales teams to close deals, PLG companies let users experience value before purchasing — think Slack, Zoom, Figma, and Notion.
In a PLG model, the product is the marketing. Users can sign up for free (freemium) or start a trial without talking to sales. They experience core value quickly — the 'aha moment' — and either convert to paid, invite teammates (viral loop), or both. Marketing's job shifts from generating leads for sales to reducing friction in the self-serve funnel and maximizing activation and expansion.
Sales-led growth (SLG) relies on sales reps to identify, qualify, demo, and close deals. It works well for complex, high-ACV products where the buyer is an executive. PLG works best for products with broad user bases, clear individual value, and natural viral loops. Many modern B2B companies use a hybrid approach: PLG for bottom-up adoption and a sales team for enterprise expansion.
PLG companies measure: Time-to-value (how quickly users reach the 'aha moment'), Activation rate (% of signups who complete key onboarding steps), Free-to-paid conversion rate (benchmark: 2–5% for freemium), Expansion revenue (Net Revenue Retention should be >110%), and Product Qualified Leads (PQLs) — users showing buying signals within the product.
PLG is a fit when: your product delivers individual value quickly (time-to-value < 5 minutes), users can experience core value without integration or setup, there's a natural sharing or collaboration mechanism, and your target users have autonomy to start using tools without IT approval. PLG is harder when: the product requires complex implementation, ROI is only visible at the organizational level, or the buyer is not the user.
Start by defining your 'aha moment' — the specific action that predicts retention. Map the steps users take to reach it. Remove friction from every step. Invest in in-product onboarding, tooltips, and activation emails. Instrument your product to track PQLs and trigger sales outreach when enterprise signals appear. Build your pricing around the value metric that scales with usage.
