Full-Stack SaaS Product Development — From 0 to Launch in 12 Weeks

A big idea, a blank canvas, a hard deadline

The founders had a validated market thesis and early LOIs from enterprise clients — but no technical team and a 12-week window before their seed funding runway required proof of traction. Building in-house wasn't an option; finding a partner who could own end-to-end product delivery was critical.

Requirements were demanding:

• Web platform and mobile app simultaneously
• Multi-tenant SaaS architecture from day one
• Enterprise-grade security and access controls
• Scalable to 10,000+ users without re-architecture
• Live with paying customers in week 12

Full-stack ownership from architecture to deployment

Kryst Digital assembled a dedicated product team — product engineer lead, frontend engineers, backend engineers, mobile developer, and DevOps — and took full ownership of the build. We ran two-week sprints with weekly demos to the founders.

• System architecture and database schema design
• Node.js / Express REST API with GraphQL layer
• React web application with TypeScript
• React Native mobile app (iOS + Android)
• AWS infrastructure (ECS, RDS, S3, CloudFront)
• CI/CD pipelines via GitHub Actions
• Multi-tenant RBAC and SSO integration

Launched on time. Grew from day one.

The platform went live in week 12 as contracted. The founders onboarded their first three enterprise clients within 48 hours of launch. Month one closed with over 3,000 users — well ahead of projections — and zero critical production incidents.

• Production launch on week 12, on schedule
• 3,000+ users in the first 30 days
• 3 enterprise clients onboarded at launch
• 99.97% uptime in first 90 days
• Series A raised 4 months post-launch
