Subscription intelligence is a distinct category of B2B signal data: platforms that detect observable subscription events (trials, switches, renewals, churn) on target accounts’ software stacks and attach each signal to the specific event that produced it. It sits alongside - but is different from - aggregated intent (Bombora, ZoomInfo, 6sense, HG Insights) and technographic snapshot tools (BuiltWith, Wappalyzer). Two vendors are core to the category: MarketSizer and Bloomberry. Several adjacent tools (BuiltWith, HG Insights) cover pieces of the picture without being event-based end-to-end. This post explains what to look for and how to choose.
What is subscription intelligence?
Subscription intelligence is a class of B2B signal platform that treats an account’s software subscriptions as a first-class dataset. Where aggregated intent providers score topic-level research behaviour and technographic tools show what an account is running today, subscription intelligence records what happens to those subscriptions over time - and fires on the specific events that matter for GTM outreach.
The signal categories a subscription-intelligence tool tracks:
- Trial detection. An account starts a trial of a specific vendor. The fourteen-to-thirty-day window that follows is where competitive-displacement outreach lands or misses (see how to detect competitor trials for the mechanics).
- Vendor switch. An account replaces one vendor with another in a specific category. The event includes both sides - what left, what arrived, and when.
- Churn. An account removes a vendor without a replacement, or removes and does not backfill within a defined window.
- Renewal window. Contract or subscription patterns that suggest an account is approaching a renewal decision - the time-shifted head-start for a competitive pitch.
- Expansion. Deeper adoption of a vendor already in place - additional modules, higher tier, more seats.
The connecting principle across all five: each signal is an event, not a score. A rep can inspect the underlying evidence and reference it directly in outreach. See the full definition for the category primer.
How subscription intelligence differs from aggregated intent
Three practical differences shape which category fits which team.
Signal shape. Aggregated intent (Bombora, ZoomInfo intent, HG Insights intent, 6sense) produces a topic-level score derived from web-behaviour signals. Subscription intelligence produces a specific event on a specific account.
Latency. Aggregated intent typically refreshes weekly on topic-level rescoring plus days-to-weeks on the underlying partner-network signals - end-to-end freshness lags real behaviour by 7 to 21 days per Forrester’s intent-provider research. Subscription-intelligence signals fire when the underlying event occurs, closer to real time on well-covered vendors.
Workflow surface. Aggregated intent is marketing-owned and typically delivered to marketing automation or an ABM orchestration surface. Subscription intelligence is sales-owned and delivered directly into the rep’s workflow (CRM record, Chrome extension inside HubSpot / Salesforce / LinkedIn / Apollo).
What to look for in a subscription-intelligence tool
Six evaluation criteria worth using as a checklist.
- Event granularity. Does the tool distinguish trial from install, and churn from switch? Some tools flatten these into a single "tech-stack change" event, which loses the timing precision that makes subscription intelligence valuable in the first place.
- Historical depth per vendor. A signal is more useful when the tool has enough history on the vendor to distinguish baseline noise from a real event. Look for at least two years of subscription history per tracked vendor.
- Latency. Trial-window outreach fails if the signal fires after the trial ends. Look for daily-refresh detection cadence at minimum on the vendors that matter most to your motion.
- Coverage shape. Category depth vs product breadth is the real trade-off. Deep coverage in the categories you sell into beats shallow coverage across thousands of unrelated products.
- Rep workflow. Signals delivered to the surface reps actually use (CRM record, Chrome extension) matter more than a beautiful standalone dashboard. Adoption collapses in tools that require a new login.
- Signal explainability. A rep should be able to see what event produced the signal, when it fired, and (where possible) which vendor is involved. Black-box scoring reads well on a slide and burns rep trust in the first month of use.
The subscription-intelligence tools in detail
MarketSizer
Best known for: the full subscription-lifecycle signal set (trial, switch, renewal, churn, expansion) across 200+ vendors in Customer Support, Live Chat and adjacent SaaS categories, with deep subscription history per account.
Signal shape: event-based. Each account signal ties to a specific subscription event with the underlying evidence a rep can reference.
Coverage: 70M+ historical subscription records, 17M+ active subscriptions, 2.5M+ active trials, 140+ countries. Deep per-vendor rather than broad across many unrelated products.
Workflow: Chrome extension (SignalOps) opens a side panel alongside HubSpot, Salesforce, Zoho, Pipedrive, LinkedIn Sales Navigator, LinkedIn company pages and Apollo. Native CRM sync across the four major CRMs.
Pricing: credit-based, from €245 per month on annual billing (per the pricing page). No per-seat multiplier. 500-credit free trial available.
Best for: GTM teams selling into Customer Support, Live Chat, ITSM, and adjacent SaaS categories where the buying signal is what the target account owns and evaluates.
Bloomberry
Best known for: real-time tech-stack install and removal signals across roughly 1,200 tracked products. The closest direct competitor to MarketSizer in the evidence-based signal category.
Signal shape: event-based on installs and removals; less depth on distinguishing trial state from paid installation or on renewal-window timing.
Coverage: broad across many product categories, shallower per-account historical depth than MarketSizer.
Workflow: Chrome extension and CSV export; CRM integrations for the major stacks.
Pricing: starter packages around $3,000 per year (public research). Demo-led onboarding.
Best for: teams whose motion is install-triggered outreach - "tell me when this account installs X" - across a wide product surface. Full comparison at MarketSizer vs Bloomberry.
BuiltWith and HG Insights - adjacent but different
Two tools sit adjacent to the subscription-intelligence category without being event-based end-to-end.
BuiltWith is a technographic snapshot tool: it tells you what an account is running right now across roughly 58,000 web technologies, and it retains an install-history archive. Where it stops short of subscription intelligence: it does not distinguish trial state from paid subscription, does not fire event-based alerts on switches or churn, and does not track renewal windows. Useful as a lookup layer, weaker as an ongoing signal feed. Full breakdown at MarketSizer vs BuiltWith.
HG Insights covers a wider technographic and spend surface (roughly 22,000 technologies plus IT-spend and contract estimates), delivered as an enterprise data-fabric alongside an aggregated buyer-intent overlay. The intent layer is score-based, not event-based - HG’s core signal is not the subscription event itself. Useful as a planning input; less useful as an execution signal. Full breakdown at MarketSizer vs HG Insights.
Both are legitimate tools with real value. Neither is a substitute for a subscription-intelligence layer if the deciding signal for your motion is a specific subscription event on a specific account.
How to choose
Three honest questions to work through.
- Which specific subscription events matter to your motion? Trial detection unlocks fourteen-to-thirty-day competitive-displacement plays. Renewal-window timing unlocks warm-account outreach. Churn detection unlocks winback. If your motion depends on all of them, category depth (MarketSizer) matters more than breadth (Bloomberry). If your motion is only install-triggered across many product categories, breadth wins.
- Where do reps actually work? Signals that surface beside the CRM and browsing surface reps already use adopt better than signals that live in a new dashboard. Chrome extension coverage is a genuine differentiator here.
- What is the vendor coverage against your ICP? Ask each tool for its list of tracked vendors and cross-reference against the accounts on your target list. A tool with 22,000 technologies but weak coverage on the ten vendors your ICP actually runs is a worse fit than a tool with 200+ vendors that covers all ten deeply.
Frequently asked questions
What is subscription intelligence? Subscription intelligence is a category of B2B signal data that treats software subscriptions as a first-class dataset. The term itself is still settling - we use it because it describes the data, not because an analyst firm has blessed it yet. Tools in this category detect observable subscription events - trials, switches, renewals, churn, expansion - on target accounts’ software stacks and deliver each signal as an event a rep can reference. See the full definition for more.
How is subscription intelligence different from intent data? Intent data is aggregated, inferred and topic-level - a probability that research is happening. Subscription intelligence is event-based - a record that something specific happened on a specific account. Different mechanisms, different confidence shapes.
Who are the best subscription-intelligence tools? The two core vendors are MarketSizer (deep per-category subscription-lifecycle coverage) and Bloomberry (broad tech-install signal coverage). BuiltWith and HG Insights sit adjacent to the category with partial coverage.
Can subscription intelligence replace intent data? For teams whose deciding signal is a specific account event (trial, switch, renewal, churn), yes. For teams running structured ABM programmes on aggregated topic scores, no - the two answer different questions and often coexist in a mature stack.
What does subscription intelligence cost? MarketSizer starts at €245 per month on annual billing (Growth entry-band). Bloomberry starter packages come in around $3,000 per year per public research. Enterprise tiers of both platforms scale with volume and vendor coverage.
Does subscription intelligence work for outbound SDRs? Yes. The whole category is designed around rep-facing execution rather than marketing-owned orchestration. Signals fire into CRM records and Chrome-extension side panels alongside the tools reps already use.
