PLG gets users in the door. PLS converts the best ones into enterprise contracts. It's the hybrid motion that most growth-stage B2B companies are building right now.
Product-led sales (PLS) is a go-to-market motion where a sales team focuses exclusively on converting high-intent, product-qualified leads - users who have already demonstrated value from a self-serve or freemium product - into larger paid contracts.
PLS depends on product usage signals to identify when to engage. The key signals:
PLG is a pure product motion: the product acquires, activates, and retains without a sales team. PLS adds sales as an acceleration layer on top of PLG. The sales team in PLS doesn't cold prospect - it monitors usage data and reaches out when signals indicate commercial readiness. This is fundamentally different from traditional SLG prospecting.
PLS works when: the product has a self-serve entry point, usage data is instrumented and accessible to sales, and the enterprise deal size justifies a sales touch. It doesn't work when: the product has no usage signals, the self-serve experience is broken, or sales still needs to extensively demo before a buyer understands the value.
AI has dramatically improved PLS signal analysis. ML models can predict enterprise conversion probability from product usage patterns with significantly higher accuracy than rule-based PQL scoring. The output: sales teams with a rank-ordered list of product users to contact, prioritized by conversion likelihood rather than account size alone.
