$10MT3
EchoSign (and the DocuSign comparison)

A Monterrey founder paid a Pakistani dev team $15,000 to build an email-capture SDK for mobile apps and sold exactly one licence at $300 a year; the $20,000 pivot that fixed a leak people could actually feel sold licences off a single webinar — and then the money ran out
