SaaS Development Agency for Startups
Launch your SaaS product without the usual chaos.
Most SaaS products fail before they launch — not because the idea is bad, but because the team is split across too many freelancers with no shared ownership. We build your SaaS product from the ground up: architecture, backend, frontend, auth, billing integration, and deployment. One team, full accountability, production-ready on delivery.
What you get
Full-stack SaaS application
Built with Next.js, Node.js, and PostgreSQL — a modern, scalable stack that handles growth without rewrites.
Authentication and user management
Secure login, OAuth, roles and permissions, team accounts — everything users expect from a production SaaS.
Subscription billing with Stripe
Plans, trials, upgrades, cancellations, and webhooks — a complete billing system that handles revenue from day one.
Admin dashboard and analytics
Internal tooling so you can manage users, monitor usage, and make product decisions based on real data.
API design and third-party integrations
RESTful or GraphQL APIs built for scale, plus integrations with the tools your users already rely on.
Who this is for
Founders building a B2B or B2C SaaS product who need the full stack built — not just a frontend. Teams who've outgrown no-code tools and need a real, scalable application.
Why Vnta
Auth, billing, and infra handled — not left to you
Built to scale from day one, not retrofitted later
Design included — no separate agency needed
Stripe billing set up and tested before launch
Common questions
What's included in SaaS development?
Full-stack application development: frontend, backend, database, authentication, Stripe billing, admin dashboard, and deployment. You get a production-ready product, not a prototype.
Do you handle Stripe billing integration?
Yes. We set up subscription plans, free trials, upgrade flows, cancellations, and Stripe webhooks so your billing works correctly from day one.
What tech stack do you use for SaaS?
Primarily Next.js for the frontend, Node.js or Hono for the backend, and PostgreSQL for the database. We choose the stack based on your product's requirements.
Can you build multi-tenant SaaS?
Yes. We design and build multi-tenant architectures with proper data isolation, team accounts, and role-based access control.
Do you include design or is that separate?
Design is included. Our team handles UI/UX design and development together — you don't need to hire a separate designer.
How long does SaaS development take?
Most SaaS products take 8–14 weeks depending on scope. A focused core product with auth, billing, and one main workflow is typically on the shorter end.
