It was never really about leads.
The engine does one thing: read the open web, verify each claim against a dated source, score what it finds against your rules, and hand back what it threw out with the reason each one failed. Point it at prospects and it is lead research. Point it at suppliers and it is due diligence.
The engine does not change. The brief does.
ONE SWEEP, RESOLVING
- Series B, hiring 2 SDRs
- Competitor tool in job spec
- 9-person agency
- Already a customer
- Mid-contract elsewhere
- No buyer for this
- Wrong geography
Every sweep looks like this. The five that failed ship with the reason — that is how you find out we drew your boundary wrong in week one.
22.5%
of a B2B contact database goes stale in a year — about 2.1% every month, compounding.
Cleanlist, 2026143 hours
to hand-verify 10,000 contacts, and it still came back 91% accurate rather than 100%.
Cleanlist, 2026One engine. Eight briefs.
A brief is three answers: what counts, what disqualifies it, and what evidence you will accept. The second is the one teams skip, and it does most of the work.

The rejections are the part that transfers.
Every one of these jobs fails the same way: a list arrives, it looks complete, and nobody can tell which rows were checked. What makes the eight one problem is not the subject matter — it is that the expensive mistake is always a row that should never have been there.
An openable URL, not a citation
Every claim carries the page it came from and the date it was read. If it 404s, it never shipped.
Blank beats guessed
Anything we could not establish comes back empty. We never pattern-match a plausible answer and call it data.
You see what failed
Rejected rows ship with the reason. That is how you find out we drew your boundary in the wrong place — in week one, not month six.
You write the brief. We argue with it.
Most briefs are too wide on the first pass. That is normal, and it is cheaper to find out before the sweep than after it.
Say what you are looking for
In a sentence, in your own words. Sector, geography, and the shape of the thing. You do not need our vocabulary.
Say what should never appear
The disqualifiers. The question everyone skips, and the one that decides whether the first sweep is useful or noise.
Read the rejections first
The first run comes back with what failed and why. If we drew the line wrong, that is where you will see it — and the brief changes.
