Find validated Emails & phone numbers with
20+ providers.
When the first source comes back empty, Haku keeps going. Every contact runs through the waterfall in cost and accuracy order and is verified against a second source before it reaches your CRM.
How the waterfall runs.
Provider after provider until the number is verified, then cross-checked before it reaches your CRM.
Three independent engines must agree. One disagreement removes the email.
Where others flag “risky” and move on, our advanced catch-all verification resolves the mailbox itself.
Every delivered email carries its own bounce probability, so you know your expected bounce rate before you send.
You only pay for mobile numbers. Landlines found are free.
Every number is checked with the carrier network. Dead lines are removed.
Line ownership is matched against your lead’s name, so reps never call a stranger.
What happens before Haku delivers contacts.
Finding a value is the easy part. 20 vendors to check whether it is good enough to hand a rep, and you are only billed for what delivers.
Coverage so you can scale globally.
Measured match rates from Haku's own runs, not vendor benchmarks. Match rate means a verified value was returned; accuracy rate means it was confirmed correct on sampling.
