Only pay for opportunities you can win

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. Higher-quality opportunities cost more credits, because they have a higher probability of converting.

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 free trial gives you 500 credits to explore the platform. You can score accounts against your ICP, view purchase intent signals, see win probability assessments, read AI-generated sales narratives, and sync to your CRM. It is a fully functional experience - just limited in volume, and valid for 14 days from signup. No credit card required.

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.

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.

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.

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.

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.

Monthly plans can be cancelled at any time; you retain access until the end of the billing period and we do not offer pro-rated refunds for partial months. Annual plans can be cancelled within 14 days of purchase for a full cash refund, minus the value of any credits already consumed. After 14 days, no cash refund is issued, but access continues in full until the end of your paid annual period. Credits purchased as top-ups are non-refundable once consumed. If you experience a technical issue that resulted in credits being incorrectly deducted, contact support and we will review within two business days.
