SaaS Development

SaaS Development Agency

Building a SaaS product involves hundreds of decisions: architecture, auth, billing, multi-tenancy, AI features, observability, deployment. SaTekk is a SaaS development agency that has made those decisions before and can ship your product in weeks, not months. We build modern full-stack SaaS applications using Next.js, Supabase, Stripe, and best-in-class tooling — from zero to production, including the AI features that make your product defensible.

Frequently asked questions

Do you build MVPs or full production products?+
Both. For early-stage startups we scope a lean MVP that validates the core value prop — typically 6–10 weeks. For funded teams with clearer specs, we build production-grade products with all the infrastructure needed to scale. We're explicit about what's MVP scope versus what you'll need later.
What tech stack do you use for SaaS?+
Our default SaaS stack: Next.js 15 (App Router) + TypeScript, Supabase (Postgres + auth + storage), Stripe for billing, Clerk or Auth.js for advanced auth, Tailwind CSS for UI, and Railway or Vercel for deployment. We adapt the stack if you have existing infrastructure or strong preferences.
How long does it take to build a SaaS?+
A lean MVP with core features — auth, billing, one or two key workflows, and basic AI features — typically takes 6–10 weeks. A more complete v1 with admin panel, analytics, multi-tenancy, and polished UI takes 12–16 weeks. We give you a detailed timeline and milestone plan before we start.
Do you hand over the source code?+
Yes, always. You own 100% of the source code and infrastructure. We use a private GitHub repo that transfers to you on project completion. We can also stay on as a development partner for ongoing features, which many clients choose.
