How We Evaluated Agencies
We scored 38 agencies across 6 dimensions weighted by importance to SaaS founders:
SaaS-specific experience
25%Building SaaS is different from websites. You need auth, billing, multi-tenancy, and admin dashboards.
Speed to MVP
20%Every week before launch is a week of lost learning. Agencies that ship in 4–8 weeks de-risk your investment.
Pricing transparency
20%Hourly billing punishes you for scope changes. Fixed-price quotes give you cost certainty.
Post-launch support
15%The launch is the beginning, not the end. You need hosting, bug fixes, and scaling help.
Communication
10%Daily or weekly updates, clear documentation, and timezone overlap matter more than you think.
Code quality
10%Clean architecture, testing coverage, and documentation determine whether you can iterate or need a rebuild.
