The point is not more data. It is a better next move.
A score is a starting point, not a verdict. MarketSizer connects the evidence to a sales decision: which account, which person and which next step.

How closely the company fits your target profile. It uses your own ICP configuration if you have set one, and the default if you have not. - Purchase IntentMedium
Competitor first detected 12 days ago.
Evidence that the company may be in market, such as competitor activity. A detected product is evidence of use, not a confirmed paid subscription. - Win ProbabilityMedium

From observation to opportunity
Raw evidence only becomes useful once MarketSizer resolves it to the right account, interprets it in context and scores it against what matters to you.
Vendor installations and removals on company domains are detected through five detection methods across several sources, then tracked over time.

How current the evidence is
New evidence is evaluated every day, including churn and renewal signals.
Trial signals typically reach your CRM within about 5 days. An estimate, not a guarantee.
A company you look up is re-checked at that moment, and only that company.
What makes the data trustworthy
- Traceable to the sourceSee which signal an opportunity came from and when it was first detected.
- Fresh enough to act onKnow when the evidence was last seen or changed.
- Historical, not isolatedUnderstand whether something is new, ongoing or old.
- Reasoning you can inspectSee why MarketSizer thinks an opportunity deserves attention.
Where evidence ends, your conversation begins
A detection is evidence of use, not proof of a contract. Your team confirms:
- Whether budget is approved
- Who owns the final decision
- Why a technology was installed
- Whether an installation is a paid subscription
- Contract terms or billing details
- Whether one signal means a company will buy
Judge it on accounts you know
“When my inbound team says a prospect is unreachable, I go to MarketSizer, see what software they are already using, and qualify them from there.”
- Pick accounts you know wellCustomers or competitors whose real stack you already know.

Questions about our data
Most asked
Where does MarketSizer's data come from?
MarketSizer detects subscription lifecycle events from observed vendor installations and removals, not from billing or payment records. We detect vendor installations on company domains through five detection methods across several sources, then combine them with company firmographics, competitive context and, on demand, business-contact details for the people at an account.
How fresh is the data?
Bulk detection refreshes daily, and new trial signals typically reach your CRM within about 5 days of the real-world event. That is an estimate, not a guarantee. Churn and renewal signals follow the same daily refresh, and a company you look up is re-checked at the time of lookup.
What is observed, what is inferred and what is predicted?
Observed: a vendor installation or removal on a company's domain, with the dates we first detected and last saw it. Inferred: a rule-based status such as trial, active or churned, and estimates such as renewal windows. Predicted: the Opportunity Score, which prioritises accounts for you. We label each layer so you can tell them apart.
How is the Opportunity Score calculated?
Opportunity Score rates how promising a company is for you, on a 0 to 5 scale, using ICP Match, Purchase Intent and Win Probability. The company page shows each pillar as High, Medium, Low or None, and ICP Match follows your own ICP configuration if you set one. It rates sales opportunity, not how certain a detection is. It is a prioritisation model, not a statement of certainty.
What happens if the data is wrong?
Flag it in the platform. We investigate and correct the detection rules if needed, or explain why we think it is right, and you are notified when the issue is resolved. No data platform is 100% perfect, so treat MarketSizer insights as prioritisation signals and check the supporting signals before acting.
Coverage & freshness
How do you define a trial?
A trial is a new vendor installation observed within the past 30 days. If a signal persists beyond 30 days, we re-classify it as an active subscription rather than a trial, so the in-market flag does not stay on forever.
How are renewal dates worked out?
Renewal windows are estimates based on when we first detected a product, not on contract data. They are not a known contract date.
Scoring & methodology
Does a detection prove a company pays for a product?
No. A detection is evidence that a company uses a product, not a confirmed paid subscription. A detected product may reflect a live integration or other observable footprint. On its own, it does not prove a current contract, paid plan, renewal date or contract owner.
What can MarketSizer not see?
We cannot see private purchasing contracts, billing or payment records, internal procurement discussions, budget approval, or why a technology was installed. A detection is evidence that a company uses a product, not proof that it pays for it.
Contact data
How does contact data differ from subscription data?
Subscription data is MarketSizer's own detection of vendor installations and removals on company domains. Contact data is different: the people at an account, and their business email and phone details, are enriched on demand from third-party business-contact providers, which are listed on our subprocessor page. The structure is inferred from job titles, not a verified reporting chart.
How long do you keep contact data, and can people ask for removal?
Enriched business-contact personal data is automatically anonymised 90 days after enrichment. Individuals may request access, rectification, erasure, restriction or portability, or object to processing, under applicable data protection law. Details are on our trust page.
Privacy & compliance
Is MarketSizer GDPR compliant?
Our policies and controls are designed to comply with EU GDPR, the UK GDPR and the Irish Data Protection Act 2018, backed by a signable Data Processing Agreement. Documents, subprocessors and retention details are on our trust page.
Where is data hosted, and which subprocessors do you use?
Primary production systems are hosted within the EEA. Some subprocessors operate in the US under recognised transfer mechanisms, such as Standard Contractual Clauses, the UK IDTA and the EU-US Data Privacy Framework where certified. The full list is on our subprocessor page.

Can I get a Data Processing Agreement?
Yes. A signable Article 28 DPA is available, along with a GDPR self-attestation. Our legitimate interests assessment is available to customers on request. See our trust page.
Do you have SOC 2?
We are preparing for a SOC 2 Type II examination. The report will be made available under NDA on completion. In the meantime, our security measures and subprocessor list are on our trust page.
