What makes this expert custom SaaS development firm different
We ship working SaaS products in 12 weeks with a fixed price and full code ownership.
Every project starts with a 2-week Roadmap phase where we define the architecture, data model, and sprint plan. You get a fixed price and timeline before we write a line of code. No scope creep, no hourly surprises.
Our team of senior engineers has shipped over 200 products across 50 countries. We use the same tools as top SaaS companies: React, Next.js, Node.js, Python, PostgreSQL, Redis, and AWS. Every project includes CI/CD, monitoring, and error tracking out of the box.
Why choose IRPR over a generic dev shop
Most agencies promise custom SaaS but deliver cookie-cutter code. We build production-ready, scalable platforms.
A generic dev shop often uses junior developers, hourly billing, and no project management. You get a bloated codebase with no documentation and no ownership.
IRPR assigns only senior engineers with 8+ years of experience. We write clean, documented code in your own repository. Every project includes a CI/CD pipeline, Sentry monitoring, and automated tests.
- Junior developers with 1-3 years experience
- Hourly billing with no cap
- No architecture documentation
- Proprietary code locked in their repo
- No monitoring or error tracking
- Scope creep and timeline overruns
- Senior engineers with 8+ years experience
- Fixed price from week 2 (Roadmap phase)
- Full architectural decisions documented in Notion
- Source code in your private GitHub repo
- Sentry error tracking and Datadog monitoring
- 12-week delivery with defined scope
