You deserve better than “hit or miss”

We know you’ve been there:

You call a prospect only to find out you dialed an old, inactive number, or even worse - a completely different person picks up. Talk about awkward phone calls and inefficiencies due to misdialing!

Now, with Cognism’s Diamond Data, you can dial with confidence, knowing you’re calling the right prospect on the right mobile number.


Not all records are created equal

Diamond Data is the most premium & accurate data asset on the market and have gone through additional layers of phone verification.

That means we have manually called every Diamond contact, confirming the identity of the prospect AND the accuracy of their contact details.


Verified based on YOUR needs

The Diamonds-on-Demand feature enables you to request us to verify a record on demand. Flag your most valuable leads and we’ll allocate our resources behind validating the contact data that YOU need to reach and close your next best customer.
