Stripo

A drag-and-drop HTML email template builder that lets marketers and designers create professional emails without writing code. The founders built it after repeatedly solving the same email design problems while running a digital agency, eventually spinning off the tool as a standalone product. Bootstrapped from day one, it grew through a subscription model into a business generating $3.7 million annually at roughly $308k per month, demonstrating that systematically solving a persistent, everyday workflow pain point can produce a highly profitable SaaS company.
