AI Lead Scoring Software

Lead scoring that explains every score in plain language

Trailspark learns what qualified means from your closed-won data, then scores product usage, demand gen, and ICP fit together. Every score explains itself in plain language your reps will actually trust.

Scoring that changes what your team does next

Not the same signals with AI on top. Better information to act on. Here's the design that gets you there.

High propensity, missing a role. Trailspark writes the gap to your CRM so sales and marketing can launch a play to bring Finance into the deal.

The problem

Most lead scoring cannot see your product users

Three common scoring patterns leave revenue on the table for modern B2B SaaS teams.

Legacy MAP scoring is blind to product usage

HubSpot, Marketo, and Pardot can only see the marketing signals they themselves collect. A trial user opening your product daily and connecting data sources looks identical to a dormant lead if they have not clicked an email.

Black-box AI scoring does not explain itself

Most AI scoring tools output a number with no narrative. Reps stop trusting the score after a few bad leads and go back to gut feel. Trust in the scoring model collapses the moment it cannot justify a decision.

ABM scoring reads different inputs entirely

6sense and Demandbase score account firmographics plus modeled third-party intent: who a company is, and research signals observed outside your properties. That tells you who might be a buyer somewhere. It can't tell you which people at the account are doing the things your closed-won buyers did.

How it works

How Trailspark evaluates an account

Four steps from raw signal to an evaluated account with reasoning. No black box.

1

Ingest signals from product, marketing, CRM, and warehouse

Flexible webhooks accept any event structure. Route product events from Segment, RudderStack, Amplitude, Mixpanel, or direct from your backend, or sync straight from BigQuery on a schedule with SQL you already trust. Pull marketing engagement from HubSpot or Marketo. Read CRM state from Salesforce or HubSpot. No schema lock-in.

2

Resolve users to their organization

Identity resolution matches users to their organization via email domain and firmographic matching. Product users who signed up with personal emails, CRM contacts at known domains, and anonymous touchpoints all connect to a single org view. This is account-level resolution, not cross-email person-level stitching.

3

Evaluate product usage, demand gen, and ICP fit together

Trailspark runs one LLM-driven evaluation across every signal source. You describe your ICP in plain language, and SparkSense can draft it from your closed-won deals so you start from real data instead of a blank page. Scores reflect the full context, not isolated signals weighted in isolation.

4

Return a score with plain-language reasoning

Every score comes with the signals that drove it, the weight applied, and a confidence percentage. Reps see why a lead is flagged hot before they pick up the phone. When a score is wrong, your team submits a written correction, and model refinement folds those corrections into the next model version you review and apply.

What's different

What makes Trailspark different

Capabilities that compound into scoring your team will actually act on.

Plain-language reasoning on every score

Every score cites the specific signals, weights, and confidence that drove it. Your reps read the reasoning, not a black-box number.

Organization-level identity resolution

Product users signed up with personal emails map to the same organization as CRM contacts at known domains. One org view across product, marketing, and CRM.

SparkSense ICP drafting

Drafts your acquisition ICP from closed-won deals: the company traits, titles, and buying roles that show up in deals you've won. You keep what fits and edit the rest.

Selective CRM creation

Scores at the org level first, creates CRM records only for users who meet criteria. Your HubSpot or Salesforce contact count reflects real pipeline.

Real-time webhook ingestion

Flexible webhooks accept any event structure from any source. No ETL pipelines, no managed connectors, no schema lock-in.

Privacy-respecting AI scoring

No PII is sent to LLM providers. Leads are referenced by internal IDs, and the model sees anonymized behavioral and firmographic context rather than names or emails.
