Micro SaaS Technical Case Studies: What made Carrd, ConvertKit so successful
/
In this video, I’m sharing real stories of Micro SaaS founders who built small, focused products that turned into highly profitable businesses—sometimes hitting six or even seven figures while staying lean. From Carrd’s $125K/month one-page website builder to ConvertKit’s creator-focused email marketing pivot, to AI-powered tools like SketchLogo AI, the common thread is clear: niche focus, fast execution, simple pricing, and channels where their users already live.
My goal is to show you that you don’t need Silicon Valley scale to win – Micro SaaS done right can replace a full-time salary or even build a multimillion-dollar business, often in months, not years.
