HubSpot Lead Scoring Alternatives in 2026
HubSpot launched Modern Lead Scoring in August 2025, a real upgrade over the legacy single-property HubSpot Score. It still leaves gaps: Combined Fit+Engagement is Enterprise-only ($3,600+/mo), there are no native Slack alerts on score thresholds, decay is group-level only, and the score history is a timeline you read through rather than a breakdown that shows what the score is made of at a glance. kenbun fills exactly those gaps.
HubSpot's Modern Lead Scoring rolled out in August 2025 and replaced the legacy 100-filter HubSpot Score property. It's a meaningful improvement: Fit and Engagement scores live as separate properties, you can have up to 5 score properties in total, group-level decay is now built in (1/3/6/12-month cadence + percentage step), and the score history graph shows a 6-month trend with the events that influenced it.
The new tool is good at what it does. For Marketing Hub Pro customers ($800/mo+) the bundled rules engine is a real working scoring system. For Enterprise customers ($3,600/mo+), Combined Fit+Engagement, AI-based scoring, and predictive lead scoring all become available. If you're on Pro and your scoring needs are straightforward, native HubSpot is often enough, don't buy a tool you don't need.
There are specific situations, though, where native scoring breaks down: sales reps openly ignoring scores after false positives, the 100-point ceiling making your top decile look identical, no native Slack alerts when a hot lead crosses threshold, and the inability to answer "why did this lead jump 30 points?" in front of a sales leader. Those are exactly the gaps kenbun was built to close, without replacing HubSpot.
The Problem
- • Combined Fit+Engagement scoring is Enterprise-only (~$3,600/mo), Pro customers must reconcile two scores manually
- • No native Slack alerts on score thresholds, alerts require hand-built workflows with Slack actions
- • Decay is group-level only (1/3/6/12-mo cadence + %), no per-event half-life curves
- • Score history is a chronological event log: you reconstruct why a lead scored by reading the timeline, instead of seeing the score's live composition at a glance
- • AND/OR rule logic is additive only inside a single rule, complex boolean conditions are hard
- • August 2025 transition broke workflows/lists referencing the legacy HubSpot Score property
What HubSpot Modern Lead Scoring is in 2026
HubSpot's Modern Lead Scoring (launched August 2025, replacing the legacy HubSpot Score) is built around two concepts: Fit (firmographic / property-based: title, industry, company size) and Engagement (behavioral: opens, clicks, page views, form fills, meetings). You can run them separately as two scores on Pro, or combine them into a single Combined score on Enterprise. Each score caps at 100 points on Pro and 500 on Enterprise.
The new tool ships group-level decay, pick a 1, 3, 6, or 12-month cadence and a percentage reduction (e.g. -25%/month, applied linearly across every event in the group). Score history shows a 6-month trend graph plus an event list. AI Lead Scoring (beta) and predictive lead scoring are Enterprise-only. Workflows can fire Slack messages when scores cross thresholds, but you have to build the workflow yourself; nothing is pre-wired.
Tier gating: Free and Starter have no scoring at all. Marketing Hub Professional ($800/mo+) unlocks Fit + Engagement separately. Marketing Hub Enterprise ($3,600/mo+) unlocks Combined, AI, predictive, and the 500-point ceiling. Per-marketing-contact pricing applies on top.

Why HubSpot Pro customers add kenbun
When HubSpot native scoring is enough
Don't buy a tool you don't need. Native HubSpot scoring is sufficient when:
- • You're on Marketing Hub Enterprise and Combined Fit+Engagement is bundled
- • Your sales team trusts the score and acts on it, the scoring system is working
- • Your scoring rules are simple enough to fit in additive criteria with group-level decay
- • You don't need Slack alerts on score thresholds (or you've built the workflow once and it works)
- • Your team won't use a separate tool, adoption is the binding constraint
kenbun extends HubSpot, doesn't replace it
kenbun is not a CRM, not a marketing automation platform, and not a contact database. We sync bidirectionally with HubSpot, your CRM stays your CRM, your contacts stay your contacts, your workflows keep firing. kenbun adds the explainable rules engine, the per-event decay, the Slack-native alerting, and the audit trail that native HubSpot scoring leaves out, then writes the resulting score back to HubSpot properties so the rest of your stack can use it.
