What is MicroSaaS? How to Create a Profitable SaaS Business with Low Investment
What is MicroSaaS?
MicroSaaS is a business model based on software as a service (SaaS), but on a smaller scale. Unlike large platforms such as robust CRMs or ERPs, a MicroSaaS solves a specific problem, usually for a well-defined niche.
This type of project is usually developed by one person or a small team, with low operating costs and a focus on recurring monthly revenue.
