Why Choose Brillnex as Your SaaS Development Partner?
AI-native by default
We build AI features into SaaS products from day one — not as bolt-ons. LLM integration, RAG pipelines, and AI-powered dashboards are part of our standard SaaS stack.
Multi-tenant from the start
We architect for multi-tenancy from project kickoff — not as a retrofit. Tenant isolation, RBAC, and plan-based feature gating are built into the data model from day one.
Offshore pricing
A SaaS MVP that costs $60k at a US agency costs $25k–$35k at Brillnex. Same senior engineers, same production quality — at offshore rates from Karachi.
Frequently Asked Questions
How long does it take to build a SaaS product?
A validated MVP with core features takes 30–60 days at Brillnex. A production-ready multi-tenant SaaS with billing, admin portals, and role-based access takes 3–6 months. Timeline depends on feature scope, number of user roles, and third-party integrations required.
What does a SaaS MVP cost?
A focused SaaS MVP at Brillnex costs $15,000–$35,000 depending on complexity. A full-featured B2B SaaS platform costs $40,000–$100,000+. Offshore pricing means these numbers are 40–60% below US or UK development agency rates.
Do you build multi-tenant SaaS?
Yes. Multi-tenancy is standard in our SaaS architecture. We implement tenant isolation at the database level, along with RBAC, subscription plan management, and tenant-specific configuration. Our Veloce case study (PropTech, Australia) is an example of a multi-tenant SaaS we delivered end-to-end.
Which tech stack do you use for SaaS?
Our primary SaaS stack is Next.js (frontend), Node.js or Python (backend), PostgreSQL (database), and AWS or Vercel (deployment). For AI features, we integrate OpenAI, Anthropic, or Google Gemini. We also use Stripe for billing and Clerk or Auth0 for authentication.
Can you add AI features to a SaaS product?
Yes — and this is one of our core strengths. We build SaaS products with AI features built in from the start, or add AI features to existing SaaS products: intelligent search, document summarisation, automated reporting, AI chatbots, and data classification.
