Contact coverage, measured: what 50 real records show before you spend a credit.

Two live segments, measured during a QA pass · late June 2026 · every number as logged

1 · The setup

During a QA pass on the reveal flow, we ran two segments live in production — searching is free in Leaderra, so measuring this cost nothing. For every record, the engine returns free on-file availability flags at search time: does this person have a known work email? A known direct mobile? Before a single credit is spent, you see the shape of your segment.

3 · What the numbers taught us — and what we changed

Here's the part most vendors wouldn't publish. Those on-file flags are pessimistic: they come from a fast pre-check, not from the full verification waterfall that runs at reveal time. Our own UI used to hard-block the reveal button whenever a flag said "no data" — and when we measured, that gate was hiding 32–40% of email reveals and 20–24% of mobile reveals that the deeper waterfall could still fill.

So we changed the product: a "no data on file" flag now softens the button instead of blocking it, with an honest tooltip — the waterfall may still find the contact, and a miss never costs a credit. The flags inform; they don't decide for you.

4 · What it means if you're evaluating us

• You can scope a segment for free. Run your ICP, look at the coverage flags across the list, and know before spending whether your niche is well-covered — the two segments above differ by 8 points on email coverage, and yours will have its own shape.
• The floor is not the ceiling.On-file flags are the guaranteed-visible floor. The reveal waterfall (multiple sources, tried cheapest-first) fills a meaningful share of the "no flag" records on top.
• Trying is free. Credits are only consumed when a verified contact actually comes back. A miss costs nothing, so a soft flag is an invitation, not a wall.
