The linked product and launch records describe the existing product. Our opportunity angle and validation plan are editorial hypotheses, not proof of customer demand.

Reach the first five buyers

Founder-led LinkedIn outreach to export-service operators

Ask five people in the named buyer group to demonstrate their current workflow. Record the frequency, cost and existing alternatives before offering a test.

Your 48-hour test

Interview 10 export-service founders; manually triage 2 inboxes; seek 3 paid pilots after comparing MailSage and Hiver.

Choose a success threshold with the buyer before testing. An interested reply alone does not establish willingness to pay.
