Product qualified lead (PQL)

Also called: product qualified lead · product-qualified lead

A PQL is a lead that has used a free trial or freemium product long enough to get real value from it, which makes product usage, not marketing engagement, the signal that says someone is ready to talk to sales.

A PQL earns its qualification differently than an MQL does. Nobody has to guess at interest from a webinar registration. The product itself already recorded what this person did.

Custify's own framing is direct: a PQL has signed up for a free trial or free version and used it long enough to get value out of it, not just created an account and left. That distinction matters. Account creation alone tells you nothing. Feature usage, repeat logins, and time to first value tell you the person is actually in the product, not just curious about it.

Who owns a PQL

Growth or customer-success operations typically own the PQL signal, since they're the team watching product usage data. That's a different owner than the MQL, which marketing tracks off content engagement, and a different owner again from the SQL, which sales confirms through a direct conversation about budget and timeline. Three signals, three teams, three different kinds of evidence that someone might buy.

In practice

Teams that ship a free trial often skip building the PQL signal at all and route every trial signup straight to sales. That's a fast way to burn a sales team's time on accounts that created a login and never opened the product again. The signal is worth building before the trial launches, not after the complaints start.

What people get wrong

People treat free trial signup and PQL as the same thing. They aren't. A PQL requires usage past some threshold that shows real engagement, not just registration. Skip that threshold and the PQL label stops meaning anything.
