PQL vs. MQL signals in product-led partner motions

As product-led growth (PLG) reshapes B2B, partner programs face a measurement fork: should partner-sourced accounts be qualified by marketing engagement (MQL) or by in-product behavior (PQL — product-qualified lead)? The two surface different partners as 'good.'

MQL qualification rewards partners who drive interest.
— Form fills, demo requests, content engagement.
— Surfaces media and content partners.
— Blind to whether the referred user ever activates.

PQL qualification rewards partners who drive usage.
— Signup-to-activation, feature adoption, seats invited, usage thresholds tied to conversion (per PLG benchmarks, activated accounts convert at multiples of un-activated ones).
— Surfaces integration partners, community contributors, and tool-adjacent referrers whose audiences actually adopt.

The consequential difference: in PLG, the gap between 'signed up' and 'activated' is where most value is created or lost. An affiliate sending high signup volume that never activates looks productive under MQL accounting and worthless under PQL accounting. The same partner, two verdicts.

This argues for PQL-aligned commissions in PLG programs — paying on activation milestones, not signups. The trade-off is attribution complexity: you must connect partner referral to in-product events, which requires identity resolution across the signup boundary, often imperfect.

Trade-off: MQL is easy to track and pay on but rewards vanity volume. PQL aligns to real value but demands product-analytics plumbing many programs lack.

Open question: Are you paying partners for accounts that signed up, or for accounts that stayed?
