A SaaS development company that takes you from idea to recurring revenue
We build multi-tenant SaaS platforms with subscriptions, billing, auth and admin baked in — on Next.js and Node.js. Whether you’re launching an MVP or scaling an existing product, we ship software your customers can rely on and your investors can see.
What we do
The hard parts of SaaS, solved before you write feature one
Every SaaS needs the same foundation: multi-tenancy, authentication, subscription billing, role-based access, an admin panel and usage analytics. We build that foundation right the first time so it scales with you — then layer your actual product on top. The result is a platform that handles real customers, real payments and real data isolation from launch, not a prototype you have to rebuild at your first hundred users.
What we build
Everything you need, under one team
SaaS MVPs
A focused, investor-ready first version that proves the model and onboards real paying users.
Multi-tenant architecture
Proper data isolation, tenant management and role-based access designed to scale.

FAQ
Questions, answered
How much does it cost to build a SaaS platform?
A SaaS MVP typically starts around $5,000–$15,000 depending on scope, with the multi-tenant, auth and billing foundation included. We send a fixed-scope plan after a discovery call.
How long does it take to launch a SaaS MVP?
A focused SaaS MVP usually ships in 6–12 weeks. We prioritise the core loop and billing so you can onboard paying users as early as possible.
Do you handle subscription billing?
Yes. We integrate Stripe or Razorpay for subscriptions, trials, metered usage, upgrades and dunning, with idempotent webhooks so revenue always reconciles.
Will the platform scale as we grow?
We build proper multi-tenancy, caching, queues and observability from the start, so the same codebase scales from your first user to thousands without a rewrite.
Can you take over an existing SaaS product?
Yes — we frequently audit, stabilise and extend existing SaaS codebases, then continue building new features from there.
