Senior SaaS Development PartnerDevelopment Partner
Your SaaS product built by senior engineers in 12 weeks. Fixed price, no surprise invoices.
IRPR is a senior SaaS development partner that builds custom SaaS products using React, Node.js, Python, AWS, and Stripe. Our engineers have shipped over 200 products across 50 countries, from healthcare platforms to fintech dashboards.
Every engagement starts with a 2-week Roadmap phase where we define scope and deliver a fixed price. Typical MVPs run 12 weeks and cost between $80K and $250K. We comply with HIPAA, PCI-DSS, and SOC 2 standards out of the box.
Founders hire us when they need a technical co-founder who ships. CTOs hire us to extend their team for a specific product launch. Product managers hire us when their internal team is at capacity and they need a reliable partner.

Why you need a senior SaaS development partner
Building SaaS products requires deep experience in multi-tenant architecture, billing, and compliance.
Most development shops lack the senior engineers needed to handle complex SaaS challenges like horizontal scaling, payment integration, and data isolation. IRPR only hires engineers with 10+ years of experience. Every team includes a lead architect, a backend engineer, and a frontend engineer who have shipped SaaS products before.
Our fixed-price model means you know exactly what your SaaS product will cost before we write a single line of code. We define scope, architecture, and timelines in the Roadmap phase. After that, we deliver on schedule or you don't pay full price.
Generic dev shop vs. a senior SaaS development partner
The difference between a team that builds and a team that ships.
Many agencies promise SaaS expertise but deliver generic CRUD apps. They use junior developers, skip testing, and hand over code that can't scale. IRPR is different because we have shipped 200+ SaaS products and we know what works.
Our engineers write code that is production-ready from day one. We set up CI/CD, monitoring, and error tracking before launch. You get a product that can handle 10,000 users on day one, not a prototype that needs rebuilding.
- junior or mid-level developers
- hourly billing with no cap
- no compliance expertise
- handoff without documentation
- no CI/CD or monitoring
- code that breaks at scale
- senior engineers only (10+ years)
- fixed price from the Roadmap
- HIPAA, PCI-DSS, SOC 2 built in
- full documentation and source code ownership
- CI/CD pipeline with GitHub Actions and Sentry
- architected for 10,000+ users from day one
Our process: from idea to shipped SaaS product
We follow a four-phase framework that de-risks your investment.
Every project starts with a 2-week Roadmap phase where we define the product, the tech stack, and the timeline. You get a fixed price and a clear scope before we build anything.
After the Roadmap, we move into Product development. Our team works in 2-week sprints with demos every Friday. You see progress weekly, not monthly. The Release phase includes deployment, monitoring, and a 30-day warranty.
What ships with your SaaS product
Every project includes these deliverables by default.
You get more than just code. We hand over everything you need to run and maintain your SaaS product. No hidden fees, no surprises.
Our standard delivery includes a production-ready application, a CI/CD pipeline, and monitoring tools. You can deploy updates yourself or we can continue as your engineering partner.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and monitoring
- AWS or GCP infrastructure with Terraform
- Stripe or Recurly billing integration
- Auth0 or Cognito authentication
- PostgreSQL database with migrations
- REST or GraphQL API documentation
- Admin dashboard with user management
- 30-day post-launch warranty

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we build.
Senior engineers only
We do not hire junior developers. Every engineer on your team has 10+ years of experience and has shipped at least 5 SaaS products. You get a team that can solve hard problems.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant SaaS products from day one. Our standard architecture includes encryption at rest, audit logs, and access controls.
Weekly demos, not monthly reports
You see your product every Friday. We demo working features, not slide decks. If something is off, we fix it the same week, not the same quarter.
Full code ownership
You own every line of code we write. We hand over the source code, the infrastructure, and the documentation. No lock-in, no licensing fees.
98% on-time delivery
We have shipped 200+ products and delivered 98% of them on schedule. Our process is predictable because we define scope before we build.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
