MVP Development Guide for SaaS Product Testing

SaaS product testing through MVP development validates product-market fit before full-scale commitment. Define testing objectives: demand validation, activation validation, retention validation, or monetization validation. Most SaaS MVPs should prioritize retention as the strongest indicator of product-market fit.

Build around a single core workflow — the one action delivering the most value. Instrument everything from day one using tools like Mixpanel or PostHog. Run cohort analysis on retention data as early as possible — a retention curve that flattens signals product-market fit, while a curve trending toward zero means iterating on features will not fix the core problem.
