Product Qualified Lead scoring for B2B SaaS
Score PQLs from the signals your product already produces. Trailspark learns which usage patterns predict conversion in your specific product and explains every score in plain language.
What is a Product Qualified Lead
A Product Qualified Lead is a user who has shown buying intent through how they use your product, not through marketing engagement. Someone who connects a production data source is a PQL. Someone who downloads an ebook is an MQL. Same company, different signal, different qualification story.
PQLs exist because product-led growth changed the funnel. A free trial signup can reach the buying decision before any marketing touchpoint fires. If your scoring model only reads marketing signals, those users are invisible to sales until someone notices them. By that point, the buying window may have closed.
PQL scoring reads product behavior the way MQL scoring reads marketing behavior. Both exist because buyer behavior is distributed across different channels and scoring models have to match where intent actually shows up.
Why MQL scoring alone misses PLG conversion
Three patterns that show up repeatedly in teams relying on marketing-only scoring for a product-led funnel.
Marketing signals lag product signals
A user connecting a production data source on day three of their trial is a stronger buying signal than that same user downloading an ebook two weeks later. MQL scoring sees the ebook but not the data source connection.
Product users often skip the funnel
A developer signs up with a personal email, gets the product running, and only pulls in their company stakeholders two weeks later. No form fill, no email opt-in, no MQL signal. By the time marketing sees them, the buying committee is already forming.
Static point models go stale
Points-based PQL scoring assigns fixed weights to events. When the product changes, the weights decay. A feature that was a strong signal six months ago becomes noise after you shipped a free-tier version.
How Trailspark scores PQLs
Four steps from raw product event to a PQL score your sales team will act on.
Ingest product events via webhooks
Forward events from Segment, RudderStack, Amplitude, Mixpanel, or directly from your backend. Any event structure. Map named signals during setup.
Resolve users to organizations
Identity resolution via domain matching connects product signups, CRM contacts, and marketing leads at the same domain to one organization view.
Learn weights from closed-won data
SparkSense analyzes your closed-won deals and derives which product signals historically correlate with conversion. No manual weight tuning required.
Return a score with reasoning
Every PQL score includes the top contributing signals, their weights, a confidence percentage, and a plain-language summary your reps can scan before they act.
Product signals that predict conversion
Four categories of product usage that show up in closed-won deals across most B2B SaaS products. Your specific product will have its own patterns, and Trailspark learns them from your data.
