Why we are a top custom application development vendor

Every project at IRPR starts with a fixed price and a clear roadmap. Our senior engineers average 12+ years of experience. We do not outsource to junior developers or offshore teams.
Our track record speaks for itself: 98% of projects deliver on time, and our uptime across all deployed applications is 99.9%. We have built for healthcare, fintech, ecommerce, and more.
How we differ from generic development shops
Not every vendor delivers on the promise of a top custom application. Here is the real difference between IRPR and the rest.
Generic development shops often work with vague timelines, hourly billing, and no compliance expertise. They keep your code in their repo and hand off a chaotic mess at the end.
IRPR works differently. We deliver fixed price, 8-12 week MVPs with full code ownership from day one. Our team is senior-only and compliance-certified.
- Vague milestones and scope creep
- Hourly billing with surprise invoices
- No HIPAA, PCI, or SOC2 expertise
- Code stays on their servers until final payment
- Handoff with no documentation or CI/CD
- Post-launch support is an extra contract
- Fixed price with clear milestones
- 8-12 week MVP timeline guaranteed
- Built-in compliance for healthcare, fintech, SaaS
- Full code ownership from day one
- CI/CD pipeline, Sentry error tracking, documentation
- Dedicated PM and post-launch support included

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 write a single line of code.
Senior engineers only
We don't have junior developers. Every engineer on your project has 10+ years of experience and has shipped at least 10 production applications. You get a vetted, senior team from day one.
Compliance built in from the start
Our team has built for HIPAA, PCI-DSS, SOC2, FERPA, and more. Compliance is not an afterthought - it is part of our development process. We handle audits and security reviews.
Async-first global team
We work across 20+ time zones with overlapping hours in US, Europe, and Asia. You get daily updates and real-time Slack communication. We move fast without forcing 9-to-5 meetings.
8-12 week MVP delivery
From kickoff to production, your MVP ships in 8-12 weeks. We have delivered in as little as 5 weeks for a fintech startup. Speed is baked into our process.
Full code ownership
You own the source code, the repo, and all IP from day one. There's no lock-in, no license fees. You can take the code and run with your own team anytime.
