Talk to a real personabout your team’s volume.

The five things B2B buyers ask us every week.
Short, plain answers — the same ones we give on a call. If your question isn’t here, send it through the form above or email us directly.
What’s the enterprise minimum?
There isn’t a hard one. Volume plans start at roughly 100k checks/month; below that the Growth and Scale tiers already cover you. We’ll write a plan that fits the actual volume you’re verifying, not a made-up floor.
Do you support SSO and SAML?
Yes, on Scale and above — OIDC and SAML both. SSO is provisioned per workspace and shows up in the dashboard under Settings once you’re a paid team.
Can we procure through AWS Marketplace?
Yes. Private offers are available on Marketplace; tell us your target monthly commit and we’ll issue the offer the same day.
Where can the data live?
Default is US. EU-only data residency is available on Scale and above, with Frankfurt-region storage and processing. AU and APAC on request.
How long until we hear back?
One business day, in your timezone. The first reply is from a person on our team, not a CRM sequence.
