- Enterprises commercialising an internal system for their market
- Teams whose MVP is buckling under real customers
- Businesses needing per-client isolation, billing and SLAs

Comparison
SaaS build approaches
| Dimension | MVP-first build | Full platform build | No-code prototype |
|---|---|---|---|
| Time to market | 10-14 weeks | 20-32 weeks | 2-4 weeks |
| Scalability ceiling | Designed to extend | High from day one | Low |
| Best for | Validating demand | Known demand, enterprise buyers | Concept testing only |
| Rework risk | Low with right architecture | Lowest | High — usually rebuilt |
What you gain
- Recurring revenue model with predictable unit economics
- Architecture designed for tenants, limits and enterprise buyers
- Instrumentation from day one, so growth decisions use data
- You own the IP, the roadmap and the customer relationship
Trade-offs to plan for
- SaaS is a long-term operating commitment, not a one-off project
- Cloud, support and compliance costs grow with the customer base
- Enterprise buyers demand security reviews that take real effort
