Only pay for opportunities you can win

Both include the whole core platform. Growth is a credit allowance you choose with the slider, from 2500 to 15000 credits a month. Custom is for organisational requirements: volumes beyond that, custom scoring models, advanced competitive insights, custom API access and webhooks, role-based permissions, multi-team support, priority support, SLAs and a customer success manager.

MarketSizer uses a credit-based model. Credits are consumed as you move an account through the funnel: first to identify it (see its ICP fit, intent signals, and win probability), then to activate it (unlock full insights, AI narratives, and workflows), and then to contact the right people (verified emails and phone numbers, billed only as you unlock them). A small success fee in credits is charged when MarketSizer detects a conversion. Stronger opportunities, meaning better fit, intent and win likelihood, cost more credits. The cost follows one published rule: 10 credits per Opportunity Score star. Worked example for a five-star opportunity: 1 credit to identify, 50 to activate, and 50 more only if it converts - about 100 credits (about €10) in total, or 51 (about €5) if it never converts. Contact unlocks are extra.

No one sets a price for an individual account. Every opportunity has an Opportunity Score from 0.5 to 5 stars, built from how well it fits your ICP, how strong its purchase intent signals are, and how likely it is to convert based on past outcomes. The credit cost is that score multiplied by 10, with a minimum of 5. You see the stars and the cost before you unlock, and unlocking an account again, by you or a teammate, never charges twice.

It depends on how far you take each account. Identifying an account costs 1 credit, so 2500 credits can identify up to 2500 accounts. Activating one costs 5 to 50 credits depending on its Opportunity Score, so the same 2500 credits covers up to 50 five-star activations, or more at lower scores. The usual approach is to identify widely and activate only the accounts you plan to pursue. Pushing an account to your CRM is free, and exporting from Discovery costs 1 credit per company. Contact unlocks are extra: 2 credits for an email, 10 for a phone number.

Four things are always free:

• Browsing the market. Unqualified accounts are free to view, always.
• Seat licences or background data you didn't act on.
• Success fees on your free trial. Your first conversions come with no bill attached.
• Conversions detected more than 12 months after activation. Long-tail attribution stops - those wins are yours.

A qualified opportunity is an account that passes three filters: it fits your ICP (based on firmographic and technographic criteria), is showing active purchase intent signals, and has a meaningful win probability based on historical outcomes in your segment. MarketSizer scores every account across all three dimensions and surfaces only those that clear your threshold - so your team never sees junk.

The success fee applies to any opportunity where MarketSizer detects a conversion, regardless of the original Opportunity Score. Higher-scored opportunities cost more credits to activate in the first place, and their success fees are proportionally scaled. The model is designed so that the higher the quality of the opportunity, the more credits you invest - but also the more value you receive when it converts.

MarketSizer detects conversions using our subscription intelligence dataset - 72 million historical subscription outcomes tracking when companies start and stop paid software subscriptions. When an account you Activated begins paying for your product, we observe that transition and apply the success fee automatically. You do not need to report conversions manually, though you can also mark them directly in-app by providing the deal ID. Every detected conversion shows you the signal type, the date, and the account - and you have 30 days to dispute any charge. If the evidence is inconclusive, we default to refunding you.

We considered it. The problem is attribution: between activating an account and a deal closing, your demos, outreach, pricing conversations, and rep quality all influence the outcome. Charging a revenue percentage would hold MarketSizer accountable for variables we don't control. Instead, we charge at the moment we can honestly say we delivered value - when an account you activated becomes a paying customer. That outcome is objective, observable, and tied directly to our data. It is also the fairest boundary we know how to draw.

If you are on an annual plan, any unused credits at the end of the month carry over to the next month within your plan year. If you downgrade at renewal, your remaining carry-over credits are forfeit. If you downgrade mid-cycle, you retain your current month's remaining credits until the end of that billing period. We recommend reviewing your usage before downgrading - the Growth plan includes usage tracking to help you make that decision.

Intent tools tell you who is researching a category. Lead gen tools sell you lists. MarketSizer does something different: it tracks real evaluation activity - active software trials, competitive displacement moments, and renewal cycles - and then scores each account by how likely you specifically are to win it. We back that with 70M+ historical subscription outcomes, not anonymous page visits or email open rates.

Results vary by market and team, but MarketSizer customers typically see a significant improvement in pipeline conversion rates compared to outbound from generic lists, because every account they pursue is pre-qualified against ICP, intent, and win likelihood. The credit model also creates natural discipline - teams focus on the highest-scored opportunities because those deliver the best return on credit spend.
