USE CASE:
Telling which company a personal email signup works for
Everything below is about telling which company a personal email signup works for, and about which signup identity method holds up on a list rather than one record. Mamba Labs builds Apify actors, and Personal Email to Company Resolver is the one here that does signup identity.

Where this starts
Half your trial signups used a Gmail or Outlook address. Some are students and hobbyists. Some are buyers at real companies who did not want sales calls yet. Without the employer you cannot route them, score them or tell your best lead from noise. Asking on the form lowers conversions, and most people skip it anyway.
Traditional Search Tools
- Reverse email lookup services. Several enrichment tools accept personal emails. Coverage is low because the email itself rarely appears in their databases.
- Asking in onboarding. A company field in the first session gets answers from people already committed. It also adds friction at the step you most want smooth.
- Search the name. Search the name from the signup with any other details you have and look for a matching profile. It works for distinctive names. Common names waste the time.
