Sidekickby Mike Parham
Sidekick is a background job processor for Ruby that started as an open source project and evolved into a million-dollar-per-year SaaS business run solo by Mike Parham. By charging $1,000-$2,000 annually for pro and enterprise tiers while keeping the base product free, Mike created a natural conversion funnel from open source users. The business grew organically to ~800 customers through word-of-mouth and product excellence, with 50-100% annual growth, demonstrating that a solo founder can build a substantial business by focusing on a niche problem and letting the product speak for itself.
