Supademo

A no-code tool that lets companies create interactive product demos and onboarding walkthroughs in minutes. Originally built as a scratch-your-own-itch project to eliminate the repetitive work of building product demos manually, it gained early traction through Reddit and organic channels before scaling into a subscription business. The founder focused on solving a narrow but persistent workflow problem — helping sales and customer success teams showcase products without engineering support. Supademo now generates over $83,000 in monthly recurring revenue, demonstrating that tightly scoped SaaS tools targeting specific pain points can grow into profitable, sustainable businesses.
