Experienced B2B SaaS Development PartnerDevelopment Partner
We build B2B SaaS products from idea to release in 12 weeks. Fixed price, senior engineers, zero fluff.
IRPR is a development studio that acts as your experienced b2b saas development partner. We use Next.js, Node.js, Python, PostgreSQL, and AWS to build multi-tenant architectures that scale from day one.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance like SOC 2, HIPAA, and PCI-DSS so you don't have to.
We work with founders who need a technical co-founder, CTOs scaling an existing product, and enterprises migrating to SaaS. Each client gets a full product team with a product manager, 2-3 senior engineers, and a DevOps lead.

Why an experienced B2B SaaS development partner matters
Building SaaS is not like building a simple app. It requires multi-tenancy, billing, and uptime guarantees from day zero.
IRPR has shipped over 200 SaaS products for clients in 50+ countries. We know the exact architecture patterns that prevent rewrites later. Every project uses infrastructure-as-code on AWS with Terraform, so environments are reproducible within hours.
We also bake in compliance from the start. If your SaaS handles health data, we add HIPAA controls in the Roadmap phase (week 2). For fintech, we set up PCI-DSS and SOC 2 evidence collection before a single line of code ships.
How IRPR is different from other B2B SaaS development partners
We charge a fixed price and ship in weeks, not months. Our senior engineers work with you, not for you.
Most development shops bill hourly and let scope creep destroy your budget. IRPR gives you a fixed quote in the Roadmap phase (week 2). If you add features later, we quote them separately — no surprise invoices.
Your code lives in your own GitHub repository from day one. We use GitHub Actions for CI/CD, Sentry for error tracking, and DataDog for monitoring. You own everything.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- Cookie-cutter MVP that needs rebuild
- No product management
- You pay for overtime
- Fixed price from week 2
- Senior engineers only (8+ years average)
- Built-in SOC 2, HIPAA, PCI-DSS
- Scalable multi-tenant architecture
- Dedicated product manager
- No surprise costs
Our process to build your B2B SaaS product
We move from idea to release in four clear phases. Each phase has a deliverable that de-risks the next.
The first phase is a 2-week Discovery where we align on market, user stories, and compliance needs. You get a product brief with wireframes and a roadmap.
The second phase is the Roadmap (week 2). We produce a fixed-price proposal and a technical architecture document. This is where we decide on AWS services, database schema, and third-party integrations.
What you get when you work with IRPR
Every project ships with a complete production-ready package. No loose ends.
You get source code in your own GitHub repo, CI/CD pipelines, monitoring, and documentation. We don't build a prototype — we build a deployable SaaS product that can handle real users from day one.
If you need ongoing support after launch, we offer maintenance contracts at a fixed monthly rate. But there is no lock-in. The code is yours, the infrastructure is yours, the IP is yours.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- AWS production environment (EC2/Fargate, RDS, S3)
- Sentry error tracking and DataDog monitoring
- Automated test suite (unit + integration)
- Multi-tenant data isolation (row-level security or per-customer DB)
- Stripe or Recurly billing integration
- Auth0 or Clerk authentication
- Admin dashboard with user and subscription management
- Deployment runbook and architecture documentation
