Counts are verified DNS signals on the primary domain, as of the last-seen date. A record proves a relationship, not seat count or spend. Logos by Logo.dev.

Counts are distinct domains carrying the platform’s records: a floor that grows every day. Refreshed monthly.

How it works

From a DNS record to a graded row

Vendors ask companies to prove they own a domain before they send mail, sign documents or log users in. That proof lives in public DNS.

  1. 1

    Observe

    We read the records every domain publishes: TXT SPF MX CNAME DMARC DKIM and 40 more.

  2. 2

    Verify

    Each record is matched to a vendor signature and graded Verified, Strong or Inferred, with first-seen and last-seen dates.

  3. 3

    Map

    Records resolve to companies, with mail provider, security posture and hosting, in one graph you can search, export or stream.

Questions

Straight answers

Where does the data come from?

Public DNS only. We read millions of domains on a schedule and match records to thousands of vendor signatures. No logins, no crawling behind authentication, no personal data.

Is a record proof of a paying customer?

No. It proves the domain published the vendor’s record, which is what turns the product on. It does not show seats, spend or whether the contract is live. Every row carries a grade and a date.

Can I monitor my own domains?

Yes, and it is free to start. Add up to 100 domains, scan them, and get change alerts. Upgrade for larger portfolios, exports and the API.

Does it connect to my CRM or SIEM?

Yes. Salesforce and HubSpot sync, a REST API and MCP connector for Claude, CSV export and webhooks for your SIEM. See the API docs.

Do you sell contacts?

No. DNSai tells you what domains run and how they are configured. Pair it with your contact provider for people.
