What Sets This Experienced Startup Web App Development Firm Apart
We ship production-grade web apps on time and on budget.
Our team consists only of senior engineers with an average of 12 years of experience. Every developer has shipped at least 5 products before joining IRPR. We have delivered 200+ web apps across 50 countries.
The 4-phase framework eliminates guesswork. You get a fixed price in week 2 (Roadmap phase). We provide a detailed spec, timeline, and cost before any code is written. 98% of projects ship on schedule.
Generic Dev Shop vs. An Experienced Startup Web App Development Firm
Not all development agencies deliver the same results.
We have seen startups waste time with agencies that start coding without a clear roadmap. Scope creep, missed deadlines, and poor code quality are common. Our clients come to us after those experiences.
IRPR works differently. Every project starts with a 1-week Idea phase where we validate assumptions. Then a 1-week Roadmap phase produces a complete spec and fixed price. No ambiguity, no surprises.
- No upfront architecture review
- Hourly billing with no price cap
- Junior or mid-level developers
- Vague timelines, frequent delays
- No compliance expertise
- Code ownership often unclear
- 4-phase framework with fixed price
- Senior engineers only (12yr avg)
- Clear spec and timeline in week 2
- 98% on-time delivery rate
- HIPAA, PCI-DSS, SOC 2 built-in
- Full code ownership, no lock-in
How Our Experienced Startup Web App Development Firm Works
We follow a repeatable process designed for speed and quality.
The 4-phase framework is built for startups that need to move fast without breaking things. Each phase has a clear deliverable and go/no-go decision point.
You are never locked into a long contract. After the Roadmap phase you can walk away with a complete spec. Once you commit, we ship the product in 8-12 weeks.
