Launching a SaaS product within 90 days requires disciplined scope control and a clear, focused roadmap.

This guide outlines a weekly plan to design, build, and launch a validation-ready SaaS product.

Phase 1 (Days 1-30): Validation and Wireframes

Identify the core problem your product solves. Draft clean layout mockups, define your target database schemas, and align your plans under a fractional CTO.

Phase 2 (Days 31-75): Core MVP Engineering

Keep features focused. Use reliable frameworks like Laravel for backend services and Next.js for client frontends. Build core features first (auth, billing integration, and primary user dashboard).

Phase 3 (Days 76-90): Beta Auditing and Launch

Run QA tests, verify security headers, and open the product to a beta group for feedback. Refine features based on customer usage and roll out public pricing plans.

Keeping your initial launch scope lean helps you validate product viability quickly.
