 💻 Micro SaaS Startup Case Studies: Big Lessons from Small Software

In the age of mega-tech and venture capital unicorns, there’s a quieter revolution happening online—Micro SaaS startups. These are small, often one-person or tiny-team software businesses that solve narrow problems for niche audiences, generating steady recurring revenue with minimal overhead.

• ✨ Small scale

• Minimal infrastructure
