Why a senior custom saas development studio matters
Building a SaaS platform requires deep expertise in architecture, security, and scale.
Many teams fail because they lack multi-tenant experience or compliance knowledge. A senior studio like IRPR builds platforms that handle 10,000+ users from day one.
We use proven patterns: tenant isolation, database sharding, rate limiting, and automated scaling. Every platform ships with monitoring via Sentry and Datadog.
Generic dev shop vs IRPR
Not all development teams are equipped to build SaaS. Here is the difference.
Generic shops treat every project like a brochure site. They miss multi-tenant isolation, subscription logic, and compliance. You end up with a rewrite after 6 months.
IRPR designs for scale from the start. We use battle-tested architectures and fixed pricing so you know exactly what you get.
- No multi-tenant experience
- Hourly billing with no cap
- No compliance knowledge
- Unclear timelines
- No post-launch support
- One-size-fits-all tech stack
- Multi-tenant from day one
- Fixed price per phase
- HIPAA/PCI/SOC 2 built in
- 8-12 week delivery
- Sentry + Datadog monitoring
- Tech stack matched to your needs
Our process for building your SaaS
We follow a four-phase process that guarantees clarity and speed.
Every project starts with a 2-week Roadmap where we define the scope, architecture, and fixed price. You get a detailed plan before any code is written.
Then we build in 2-week sprints with continuous demos. You see progress every Friday. No surprises.
What ships with your SaaS platform
Every project includes these deliverables by default. No hidden extras.
We believe in full transparency. You get the source code, infrastructure, and monitoring from day one. Nothing is locked behind a paywall.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- AWS infrastructure as code (Terraform)
- Stripe subscription integration
- Multi-tenant database architecture
- Admin dashboard with analytics
- API documentation (Swagger)
- Sentry error tracking
- Datadog monitoring
- User authentication (Auth0 or Clerk)
