PQL (Product-Qualified Lead)
PQL is a lead that's shown product behaviour indicating buying intent — used a key feature, hit a paywall, invited teammates, exceeded free-tier limits. PQL converts 5-10x better than MQL (Marketing-Qualified Lead) because behaviour is a stronger signal than form-fill.
More detail
PQL scoring needs product usage data + a scoring model. Tools: Endgame, Pocus, MadKudu, or a custom model. For SaaS with self-serve onboarding, PQL is the highest-converting lead source. Aiprosol's Lead Generation Playbook covers PQL scoring as part of the 4-component model.
