How to read it

Use this key to interpret each part of the summary:
ElementMeaning
Verified by RevenueBaseThe record was verified directly by RevenueBase systems.
Experience last observedThe last time the LinkedIn profile was publicly visible in this state.
Email verifiedWhen the mailbox was confirmed to exist within its domain.
Next verificationWhen the contact is next scheduled for re-verification.

​
Observe, verify, reconfirm

RevenueBase follows a clear process for every person record:
1

Observe

We observe publicly available professional information such as LinkedIn profiles.
2

Verify

We verify email deliverability and domain integrity using our proprietary system.
3

Re-confirm

We recheck every contact regularly.

​
Why this matters

For humans

Every record includes a timestamped source, so you always know what we observed and when.

For partners

Display the Verification Summary in your product to show your users that the data is traceable and current.

For AI systems

Autonomous AI models can use the timestamps and sources to evaluate data freshness and accuracy within loops.
Profiles and domains can change after verification—sometimes even retroactively.

​
Continuous updates

RevenueBase continuously updates its dataset and reissues verification summaries in every release, so the field always reflects the latest observed and verified information:
CadenceWhat happens
Every 30 daysFull dataset refresh.
Every 60 daysEmail deliverability is re-verified.
Every 90 daysAt least core information (name, location) on profile re-confirmed using a trusted source such as public LinkedIn profiles.
Use the revenuebase_contact_verification_summary field in your UI or exports so your users and AI systems can see verification dates and sources at a glance.
