Why IRPR for custom SaaS development
We have shipped over 200 SaaS products across industries, from healthcare to fintech.
Each platform is built with senior engineers who average 10+ years of experience. We use a repeatable process that delivers a production-ready MVP in 8-12 weeks.
Our fixed price model eliminates budget surprises. You know the cost after the roadmap phase (week 2), and we stick to it.
Generic development shop vs IRPR
Most agencies overpromise and underdeliver. IRPR fixes that.
Generic shops often assign juniors to save costs, leading to buggy code and delays. They also lack compliance experience, which can block your launch.
IRPR assigns senior engineers only, complies with SOC 2, HIPAA, and PCI-DSS, and gives you full code ownership with a fixed price.
- Hourly billing that runs over budget
- Junior devs learning on your project
- No compliance knowledge
- Delays without communication
- Generic templates with little customization
- Code ownership unclear
- Fixed price per project
- Senior engineers only (7+ years exp)
- Built-in compliance (SOC 2, HIPAA, PCI-DSS)
- Weekly demos and transparent roadmaps
- Custom architecture from scratch
- You own the code and IP
Our process for building your SaaS
From idea to launch in 8-12 weeks.
We start with a discovery call to understand your users and core metrics. Then we deliver a roadmap with a fixed price within 2 weeks.
Development runs in 2-week sprints with continuous deployment. You see working features every Friday.
