SaaS Development

Build SaaS that
scales from day one.

We build production-ready SaaS products — from validated MVP to enterprise multi-tenant platforms. React, Next.js, Node.js, Stripe billing, and AWS deployment. Every time.

The problem

Most SaaS agencies ship a demo. You get a nice UI but discover the architecture won't hold up past 100 users — and a full rewrite six months later.

Our approach

We start every project with a technical specification. Architecture, database design, and infrastructure decisions are made before a single line of product code is written.

The result

A production-ready SaaS codebase you actually own — with auth, billing, CI/CD, and cloud deployment already in place. Built to last, not to be rewritten.

What's Included

NextAuth / Clerk, RBAC, SSO-ready

Admin dashboard

User management, metrics, settings

CI/CD pipeline

GitHub Actions, preview envs, staging

AWS deployment

ECS, RDS, S3, CloudFront — production

Security hardening

3 months post-launch support

Bug fixes, monitoring, guidance

Our Process

From idea to live
product in 10 weeks.

A proven process refined across 10+ SaaS products. No surprises — you see working software every Friday and own the codebase from day one.

01Week 1

Discovery & Scope

We deep-dive into your product vision, target users, and business model. We leave with a detailed technical spec, architecture diagram, and a fixed-scope delivery plan.

Deliverables

  • Technical specification
  • Architecture diagram
  • Project timeline
  • Fixed-price quote
02Week 2–3

Design & Architecture

In-house designers produce high-fidelity Figma screens. Engineers set up the monorepo, database schema, CI/CD, and core infrastructure in parallel.

Deliverables

  • Figma designs (all screens)
  • Database schema
  • API contract (OpenAPI)
  • Development environment
03Week 3–7

Core Development

Sprints with weekly demos. We build auth, billing, multi-tenancy, the core product features, and the admin dashboard. You see working software every Friday.

Deliverables

  • Auth + onboarding flow
  • Stripe billing integration
  • Core product features
  • Admin panel
04Week 7–9

Integrations & QA

Third-party integrations, edge case handling, performance testing, and security review. We run load tests and fix everything before it ships.

Deliverables

  • Third-party integrations
  • End-to-end test suite
  • Performance audit
  • Security review
05Week 9–10

Launch & Handover

Production deployment, monitoring setup, and a 2-hour handover call with your team. We document every architectural decision and stay on-call for 90 days.

Deliverables

  • Production deployment
  • Runbook & documentation
  • Monitoring & alerts
  • 90-day support period
Tech Stack

Specialisations

Three ways we
can work together.

01

Validate fast. Build right.

SaaS MVP Development

We scope and ship production-ready MVPs in 6–10 weeks. Not throwaway prototypes — real codebases with auth, billing, and CI/CD already in place, ready to scale the moment you get traction.

  • Fixed-scope, fixed-price engagements
  • Full-stack React + Node.js architecture
  • Stripe billing + auth built-in from day one
  • Launch-ready in 6–10 weeks
  • Designed to scale, not to be rewritten
02

One platform. Thousands of tenants.

Multi-Tenant Architecture

We architect SaaS platforms where each customer's data is completely isolated — whether that's row-level security in a shared database or per-tenant schemas. Built for compliance, performance, and growth.

  • Row-level security (PostgreSQL RLS) or schema isolation
  • Tenant-scoped RBAC and permission systems
  • Custom domains and white-labelling support
  • Subscription tiers with usage metering
  • Designed for SOC2 / GDPR readiness
03

Your product is growing. Your codebase should too.

SaaS Scaling & Migration

We audit your existing SaaS product, identify bottlenecks, and re-architect the parts that are slowing you down — without a full rewrite and without taking the product offline.

  • Codebase audit & technical debt assessment
  • Database performance optimisation & indexing
  • Microservice extraction from monoliths
  • Zero-downtime migration planning
  • Performance load testing & benchmarks
Who It's For

Built for teams
serious about SaaS.

Funded Startups

You have a clear idea, seed or Series A funding, and need to ship a real product — not a prototype. We move fast without cutting the corners that matter.

  • Pre-product / early PMF stage
  • Need to move in weeks, not months
  • Want a technical co-founder, not just a vendor

Bootstrap Founders

You're building lean. Every dollar counts. We'll scope the smallest version that proves your thesis and build it cleanly enough that you can iterate fast.

  • Tight budget, high ambition
  • Solo or small founding team
  • Need to own the codebase long-term

Enterprises Launching SaaS

Your company wants to spin up a SaaS product alongside its core business. You need a reliable team to own the technical execution end-to-end.

  • Spinning up a new SaaS arm
  • Internal team lacks SaaS experience
  • Needs security, compliance, and governance
FAQ

Common
questions.

Can't find what you're looking for?

Ask us directly
How long does it take to build a SaaS MVP?
For a well-scoped MVP — core features, auth, billing, and deployment — we typically deliver in 6–10 weeks. The timeline depends on complexity, the number of user roles, and integration requirements. We define the exact scope and timeline in the discovery phase before any development begins.
What tech stack do you use for SaaS development?
Our primary stack is React + Next.js on the frontend and Node.js (NestJS or Express) on the backend, with PostgreSQL as the primary database and Redis for caching and queues. For deployment we use AWS (ECS, RDS, S3) or Vercel. We choose the right tools for your specific requirements — not just what's trendy.
Can you build a multi-tenant SaaS from scratch?
Yes — multi-tenancy is one of our core specialisations. We design the data isolation strategy in the discovery phase: row-level security with PostgreSQL RLS is our default for most products. For compliance-heavy use cases (healthcare, finance) we can use schema-per-tenant isolation. Both approaches come with proper RBAC, audit logging, and subscription management.
Do you handle Stripe integration for billing?
Yes, we integrate Stripe Billing end-to-end — subscription plans, free trials, per-seat and usage-based metering, proration, failed payment recovery (dunning), and invoicing. We also set up the customer portal so your users can manage their own subscriptions. Stripe Connect is available for marketplace-style products.
Do you work on existing SaaS products or only new ones?
Both. For new products we run our full discovery-to-launch process. For existing products we start with a technical audit — we review the codebase, database schema, infrastructure, and test coverage, then present a prioritised improvement roadmap. We can take on ongoing engineering capacity or a specific scoped project.
What happens after launch?
Every engagement includes a 90-day post-launch support period. We monitor the production environment, respond to bug reports, and are available for questions. After 90 days, clients typically continue with a monthly retainer for ongoing feature development, or hand off to their in-house team with full documentation and a recorded walkthrough.
