What an ICP fit score is
An ICP fit score measures how closely an account matches your Ideal Customer Profile on firmographic, technographic, and behavioral signals. Pick the signals your best customers share, weight them, and score each account out of 100. High scores go to outbound first. Cleanlist AI can score leads against your criteria at 5 credits per record.

How does this tool work?
ICP scoring helps a sales team spend its time on the accounts most likely to buy. Yet most teams spray outreach evenly across their entire database because they don't have a fast way to score accounts.
To score an account yourself, write down the signals your best customers share: industry, employee count, revenue range, tech stack, funding, growth signals, decision-maker level and engagement. Give each signal a weight, score the account on each one, and add them up out of 100. Use the result to qualify inbound leads before SDR handoff, prioritize a target account list before outbound, or sanity-check a deal before investing rep time.
To score at scale, Cleanlist AI scores leads against your criteria at 5 credits per record. Every new workspace starts with 14 days of Pro (up to 3 seats, 250 credits).

Frequently asked questions
Short answers about the ICP Fit Score Calculator: what it checks, what it costs and where it stops.
All free toolsHow does ICP fit scoring work?
It scores a target account 0-100 against the firmographic, technographic, and behavioral signals that correlate with closed-won deals in your own history. A common set covers industry, employee count, revenue range, tech stack, recent funding, growth signals, decision-maker level, and engagement. Each dimension gets a sub-score, and the overall score is a weighted composite.
What's a good ICP fit score?
It depends on your own model, so set the bands from your closed-won history. A common setup uses three tiers: high-fit accounts go to outbound first, medium-fit accounts get qualified further before a rep spends time, and low-fit accounts get deprioritized or skipped. Review the bands once you have enough deals to compare them against.
How accurate is a generic ICP score vs one built on your data?
A generic B2B framework is a fair starting point, but it can't know which signals matter most for your business. Criteria drawn from your own closed-won accounts tell you more. Cleanlist AI scores leads against the criteria you set.
Can I score multiple accounts at once?
A spreadsheet works for a short list: put the signals in columns, add a weighted formula such as SUMPRODUCT, and sort. For bulk scoring, upload a CSV to Cleanlist AI, which scores each record against your criteria at 5 credits per record so you can prioritize outreach.
What's the difference between ICP and persona scoring?
ICP scores the company. Persona scoring scores the individual contact within that company. Both matter: a perfect-ICP company with the wrong persona is still a hard sell. Cleanlist AI scores both layers.
Should I use ICP scoring for every account?
Yes. Set up automatic scoring at MQL to SQL conversion, prioritize high-fit accounts for AEs, route medium-fit accounts to nurture, and disqualify low-fit accounts.
