Frequently Asked Questions

How fast can you deliver a production-ready SaaS MVP?

A typical full-stack SaaS MVP is architected, developed, and deployed to production within 3 to 4 weeks. This includes database schema design, authentication, multi-tenant security, core workflow features, Stripe subscription billing, and responsive UI.

How do you handle multi-tenant data isolation in SaaS applications?

We enforce multi-tenancy directly at the database layer using PostgreSQL Row-Level Security (RLS) policies tied to tenant organization IDs in authentication JWT tokens. This ensures absolute data isolation and zero cross-tenant data leaks.

Do I own 100% of the code and intellectual property?

Yes, 100%. Upon project completion, full ownership of the GitHub repositories, cloud database instances, API keys, and deployment pipelines is transferred entirely to you with zero proprietary vendor lock-in.

How do we collaborate and track progress during the build?

We work in structured weekly sprints with daily asynchronous Slack/Loom updates and weekly interactive milestone demos. You have continuous access to a live staging environment to test features as they are built.

What happens after the SaaS product launches?

Every turnkey build includes 30 days of post-launch hypercare support covering bug fixes, performance monitoring, and team onboarding to ensure a seamless operational handover.
