Types of SaaS Models
SaaS is not a one-size-fits-all model. It comes in different shapes and sizes depending on who it’s built for, what it solves, and how big the operation is.
Understanding these types is crucial for founders to:
- Identify their ideal customer
- Focus their marketing strategy
- Plan features and pricing correctly

- Plausible Analytics (privacy-focused website analytics)
- Tweet Hunter (for Twitter automation)
Key Characteristics:
- Minimal overhead
- No external funding needed
- Built once, sold many times
- Perfect for indie hackers or part-time creators
🔹 Niche SaaS
Focused not just on a small product scope, but also a specific audience — such as local freelancers, podcasters, or personal coaches.
