Clear terms around exclusivity, verification, delivery, and sourcing.
An exclusive B2B lead is a business contact licensed to a single buyer within a given territory and vertical — it's never resold to a direct competitor during the agreed exclusivity period. Unlike a shared lead, sold to several buyers at once (the model most self-serve platforms use), an exclusive lead has a single owner. That changes the whole outreach dynamic: no race against three other companies dialing the same number the same day.
Around $0.15 per verification attempt. But since not every attempt results in a valid contact, the real cost per lead actually delivered rises to about $0.24.
A shared lead is sold to several buyers at once. An exclusive lead is licensed to just one — and that single fact consistently changes the price. In industries where this pattern has been documented in more detail (insurance, mortgages, roofing), an exclusive lead consistently costs 2 to 3 times more than the same lead sold as shared. It isn't an arbitrary markup — it's what it's worth to remove the race against other buyers for the same contact.
That, before delivery, the email was confirmed to exist and the phone number was confirmed active — a real check, not a syntax validation. One-by-one verification happens lead by lead, not by sampling the batch. It's the difference between "95% of this list probably works" and "every contact on this list was confirmed before it was delivered to you."
3 business days from when the search criteria are confirmed — ICP, volume, and enrichment tier. For recurring supply, delivery becomes a fixed cadence agreed in advance: weekly, biweekly, or monthly, matched to the buyer's consumption pace.
It's the classification given to a lead when it has a documented basis for phone or SMS contact, not just email. It differs from the Prospecting tier, which is suitable for email or LinkedIn but not for calling. The distinction exists because not every contact record is equally fit for every channel — mixing the two up is the most common way an outreach team gets into trouble without realizing it.
Between $0.25 and $1.00 per contact with phone, depending on the platform — and in none of the three cases is the data exclusive. *On top of a reference annual subscription of US$15,000–45,000. Data from all three platforms can be available, at the same time, to every other subscriber — which is why two competing companies sometimes end up calling the same prospect the same week.
It depends on three variables: the data's enrichment tier, the block's volume, and whether it's a one-time purchase or recurring supply. Enrichment tier: higher enrichment and verification means a higher price per lead. Volume: large blocks (10,000 leads or more) get a volume discount. Recurrence: contracting recurring supply instead of a one-time block earns an additional discount.
Yes — a free trial sample of 100 to 200 leads, at the same filtering and verification standard as a real block. It isn't a scaled-down demo or a lower-quality sample meant to hook you — it's exactly the same standard a paying client would receive, so the purchase decision gets made on real data, not on anyone's word.
From public, lawfully accessible sources, processed with artificial intelligence for filtering and segmentation, and manually verified before delivery. No platform whose terms of service expressly prohibit resale of their data is used as a source.
