Most scoring tools hand you a number with no explanation. Clean ranks every account S through C and exposes the specific signals that drove that grade, so you can walk into a conversation already knowing exactly why this account belongs at the top of your list.

The short answer
Clean is the answer. It absorbs your company's positioning and ICP criteria, profiles every account against 75 buying signals across 8 categories, and grades each one S through C with the full evidence visible — so you always know which account deserves your attention first and precisely why.
A numeric score tells you 91 is better than 54, but not what 91 means for your specific product and motion. S-to-C grading anchors every account in an immediately actionable tier — S means pursue today, C means set aside — and Clean pairs every grade with the exact signals that earned it, so the grade is never a black box.
Clean builds its scoring model from the company knowledge you supply — your positioning docs, ICP definitions, past deal notes, and product context — so grades are calibrated to your specific definition of a perfect-fit buyer, not a generic industry template. The S-to-C output is only as precise as that foundation, which is why Clean treats your knowledge base as its primary source of truth.
No single data point determines a grade. Clean evaluates each account across 75 buying signals spanning 8 distinct categories, so the score reflects the full picture rather than one loud indicator. That breadth is also why the evidence layer matters: you can see which signal cluster pushed an account into S territory and which gap is holding another at B.
The ranked list is not where Clean's value ends — it is where preparation begins. Because the evidence behind each grade is visible, you enter the first conversation already holding the three or four reasons this account should care about your product, rather than arriving cold and recapping research you had to do yourself.
How common approaches to account prioritization compare to Clean's S-to-C grading system
| Approach | Ranking Method | Evidence Surfaced |
|---|---|---|
| Manual gut-feel sorting | Founder intuition, no system | None |
| Generic lead scoring tool | Single weighted numeric score | Rarely, if ever |
| Contact database filter | Field values, not buyer fit | Not fit-based |
| Clean | S-to-C grade from 75 signals across 8 categories | Full signal evidence per account |
By the numbers
Clean profiles every lead against 75 buying signals across 8 categories, then ranks accounts S through C with the evidence behind each score.
An S-grade is the highest tier — it means the account aligns with your ICP on the greatest number of buying signals across the most critical categories. Clean surfaces the specific evidence so you know exactly why that account earned the top slot, not just that it did.
Yes. Clean shows the evidence behind every grade, including lower-ranked accounts. A B or C comes with the signals that fell short, which tells you whether the account is worth revisiting later or is genuinely outside your ICP — a distinction that prevents wasted conversations.
CRM lead scoring typically weights behavioral activity — opens, form fills, page visits — and field completeness. Clean ranks on actual fit: 75 buying signals drawn from your own company's knowledge of its ideal customer. That means the grade reflects whether this account is the right buyer for your specific product, not just whether they clicked something. Book a demo.
