The problem it solves

Fake or mistyped email addresses from web forms quietly pollute your CRM and waste your sales team's time chasing leads that never respond. Sorting the good leads from the junk by hand isn't something anyone has time for.

Who it fits

Best for sales teams who collect leads through web forms and want a clean, trustworthy CRM.

How it works

  1. A lead submits a form and the details are sent to the system
  2. AI verifies the email address and checks whether it's deliverable
  3. Each lead is classified as valid, risky, or blocked
  4. Valid leads are added to HubSpot automatically
  5. Risky leads are added but flagged, and blocked leads trigger a Slack alert instead of entering the CRM
What you get

Invalid leads kept out of your CRM

You get every new lead's email verified automatically, with only clean contacts added to HubSpot and risky ones flagged for you.

What you get

A HubSpot CRM populated only with verified leads, plus Slack alerts for anything risky or blocked.

What you need

A HubSpot account, a Slack workspace, an OpenAI API key, and an email verification service.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
