Why IRPR is the best custom application development firm
We measure our success by your delivery date.
IRPR has shipped over 200 custom applications across 50 countries. Our senior engineers average 12 years of experience and have built for startups, enterprises, and governments.
Every engagement starts with a fixed-price Roadmap. You know the cost and timeline before a line of code is written. We deliver on time or we discount the project.
Generic dev shop vs IRPR
Most firms charge hourly and miss deadlines. We don't.
Typical dev agencies start with an open-ended SOW. They bill by the hour and often deliver late. IRPR starts with a fixed quote after a 2-week Roadmap phase. We ship in 8-12 weeks or your money back.
Our developers are senior engineers with 10+ years experience. No junior interns, no outsourcing. Every line of code is written by hands that have built production applications at scale.
- Hourly billing with no cap
- Unclear timeline and scope creep
- Junior developers assigned to your project
- No fixed price guarantee
- Code quality varies
- No post-launch support
- Fixed price after 2-week Roadmap
- 8-12 week delivery guaranteed
- Senior engineers only (avg 12 years exp)

How we build custom applications in 4 phases
Our process reduces risk and ensures on-time delivery.
We start every engagement with a 2-week Roadmap to define scope and price. Then we build your MVP in 8-12 weeks.
Each phase ends with a demo and sign-off. You see progress every week.
