B2B funnels get polluted by personal-email signups, fake company names and bots. Verifying and qualifying at the form keeps your pipeline real. Here's how.

The B2B signup problem

Free-email signups (gmail, outlook) and fake or mistyped company names slip into your funnel, inflating lead counts and wasting sales time on contacts that aren't real businesses.

Verify the email and the company

  • Verify the email is valid and not disposable.
  • Resolve the company name to a real domain.
  • Flag free-email signups for routing or extra qualification.
  • Block obvious bot and fake-detail patterns.

Real-time at the form

A form guard does this the instant someone submits — so bad B2B leads never reach your CRM and your sales team only follows up on real companies.

Cleaner pipeline, honest metrics

Qualifying at the form means your lead counts, conversion rates and pipeline reflect real businesses, not noise.
