Over-Built
Tech complexity exceeds what the current business stage requires. Capital and engineering hours are spent on capability not needed yet.
The SaaS Stage-Fit Matrix
A diagnostic framework for evaluating whether your SaaS architecture complexity matches your business stage. Architecture is not good or bad in absolute terms — it is stage-fit or stage-misfit.
The Three Zones
Stage-Optimized
Tech complexity matches the current business stage. Engineering capacity is well-allocated to stage-appropriate work.
Under-Built
Tech complexity is below what the current business stage requires. Users are already feeling the pain, or will at the next inflection point.
Frequently Asked Questions
What is the SaaS Stage-Fit Matrix?
A diagnostic framework that evaluates whether your SaaS architecture complexity matches your current business stage.
How is it different from DORA or AWS Well-Architected?
DORA measures delivery performance. Well-Architected evaluates best practices. Stage-Fit evaluates alignment between architecture and business stage.
What architecture should a Seed-stage SaaS use?
Most Seed-stage SaaS should use a monolith with a single database and basic CI/CD.
How do I know if my SaaS is over-engineered?
Over-engineering shows up as engineering capacity consumed by maintaining infrastructure users do not need yet.
When should a $100K MRR SaaS adopt microservices?
The Stage-Fit Matrix evaluates this based on team size, customer type, compliance, and trigger events.
