Introduction
Micro-SaaS is rapidly redefining the software landscape for entrepreneurs, freelancers, and agile tech teams. Essentially, micro-SaaS refers to small-scale SaaS businesses that solve highly specific problems for niche audiences—often developed and operated by solo founders or lean teams, and generating recurring revenue with minimal overhead. As SaaS markets mature and specialization deepens, micro-SaaS offers an accessible path to innovation, independence, and profit. In 2025 and beyond, these nimble ventures will continue to shape both the business models and technical evolution of the SaaS world.
