Frequently Asked Questions

What is a SaaS startup?

SaaS (Software as a Service) is a software distribution model where applications are hosted in the cloud and provided to customers over the internet on a subscription basis. Instead of buying and installing software, users pay a monthly or annual fee for access.

How much can a micro-SaaS make?

Micro-SaaS products typically target $1K-$10K monthly recurring revenue (MRR). Many solo founders achieve $5K-$20K/month with focused niche products. The key is solving a specific problem extremely well.

What tech stack is best for SaaS in 2026?

Popular stacks include Next.js + Supabase for rapid development, or traditional choices like Rails or Django. The best stack is one you can ship quickly with. AI coding tools like Cursor have made full-stack development accessible to more founders.

How long does it take to build a SaaS MVP?

With modern tools and AI assistance, a focused MVP can be built in a weekend (8-16 hours). The key is scoping aggressively—launch with one core feature that delivers clear value, then iterate based on user feedback.
