SaaS MVP Development Agency
Greta builds SaaS MVPs in 4–8 weeks. We are 20x faster and 100x cheaper than a traditional agency. Subscription billing, multi-tenant auth, B2B and B2C — all production-ready from day one. No technical co-founder needed.
What is a SaaS MVP?
SaaS stands for Software as a Service. It is software that users pay for on a subscription — they log in and pay monthly or annually instead of buying a one-time licence. Slack, Notion, HubSpot, Zoom — these are all SaaS products.
An MVP is the first working version of your product. You can read more about what an MVP is if this is your first time building software. The short version: an MVP lets you test your idea with real users before spending big on a full build.
A SaaS MVP is the first working version of a subscription software product. It has the core feature that solves your users' problem, plus the basics every SaaS needs: sign-up, login, billing, and a dashboard. Everything else comes after you have validated the idea with real paying customers.
The SaaS MVP trap
Most SaaS founders fall into one of two traps.
The first trap is building too much. You spend 12 months building every feature you ever imagined. You launch, and users only actually use two of them. You wasted 10 months and $100,000+ on features no one needed.
The second trap is building too cheaply. You hire a freelancer or use a no-code tool to get something live fast. It works for demos but falls apart when 50 users sign up at once. The technical debt makes it impossible to add features without rebuilding from scratch.
Greta is designed to avoid both traps. We help you scope tight and build fast — but we also build production-ready. No shortcuts on security, scalability, or code quality that come back to bite you later.
