B2B data provider benchmark, September 2026

02

Reach against accuracy

A record is lost in one of two places: the provider never returns it, or the answer it returns is not verified accurate, because the title differs, the employer is one the person has left, or the answer cannot be verified.

The top right corner is the only place worth being: answering often, and answering correctly. Nobody is there. The distance from it is what a provider costs you, in rows you never get plus rows you cannot use.

Data quality after a job change

05

Results by segment: country, seniority, company size

Six dimensions, and for each one the count of segments a provider leads before any single row is read. A row is ranked only above 100 contacts, and a row whose top two values sit inside each other's confidence interval is marked as too close to separate.

Where each provider falls behind, including us. On accurate records per 100, BlitzAPI is behind on 1 of the 36 ranked segments, Apollo on 35, Prospeo, QuickEnrich, MoltSets and GetLeads.io on all 36. The table above carries every value behind that sentence; switch the measure to read the same rows on coverage or on accuracy, where the order is not the same.

The tables above carry every value behind that sentence. This printed copy shows accurate records per 100 only; the same rows on coverage and on accuracy, where the order is not the same, are on the web page.

The counts above are on accurate records per 100. Switch the measure to coverage and the picture moves: Apollo returns more contacts than every other provider on 5 of the 6 cohorts, and Prospeo returns more on New jobs · Europe (93.8%).

Head to head: every provider pair

If you are replacing one provider with another, this is the comparison that matters. Each pair is scored only on the contacts they both returned, so a provider cannot look good here by staying silent.

One page per pair against BlitzAPI. Each one sets out, in order, the main measures side by side (accurate records per 100, coverage, accuracy, the wrong title rate and the stale employer rate), each counted on the whole list or on what each provider returned, with the count of published segment comparisons the other provider leads or ties; each provider's answers split into four verdicts; the pair scored on the contacts both returned; and how both hold up after a job change: vs Apollo, vs Prospeo, vs QuickEnrich, vs MoltSets and vs GetLeads.io.

07

Waterfall: what a second provider adds

The usual answer to a coverage gap is to buy a second provider and fall back to it. Here is what that buys, measured rather than assumed: each step only queries the contacts no earlier step returned.

The ceiling for any combination is 91.2 per 100, the share of contacts where at least one of the 6 providers is right. Reaching it would mean knowing which answers are wrong without a reference, which is the whole problem.

08

Every measure, side by side

The measures that rank, in one table, including the rows that flatter nobody. Colour is a reading aid only, computed inside each row: green towards the better end, amber towards the weaker one. Rows that describe a run rather than score it, such as the query date, carry no colour and no mark.

No price appears anywhere on this page, and no billing unit either. None of the providers tested publishes a per-unit list price we could verify and date, and a cost comparison built on quoted rates would not be checkable. Ask each provider for the rate it quotes you, and apply it to the volume you actually send.
