Why businesses choose IRPR for B2B web apps
Our clients come for the senior talent and stay for the predictable delivery.
Every IRPR team is composed of developers with 8+ years of experience. We do not hire juniors or outsource overseas. This means your product is built right the first time with clean architecture, test coverage, and security audits.
After shipping 200+ products across 50 countries, we have refined a repeatable process. From Roadmap to Release, every milestone is defined upfront. 98% of our projects deliver on time with no budget overrun.
How IRPR differs from a standard dev shop
Most agencies claim senior talent but deliver junior work. IRPR is built differently.
We only take projects we can execute with our senior team. No bench, no subcontractors. Every developer is a full-time IRPR employee based in the US and Europe.
Our fixed-price model means the cost is locked from the Roadmap phase. If the scope changes, we adjust the quote transparently. There are no hourly surprises.
- Junior-heavy teams with 1-2 seniors
- Hourly billing with unpredictable totals
- No compliance expertise (HIPAA, PCI, SOC 2)
- Sparse documentation and no code reviews
- Locked into one stack (e.g., PHP)
- Long 6+ month deliveries for simple apps
- All senior engineers (8+ years)
- Fixed price from day one, no surprises
- HIPAA, PCI-DSS, SOC 2 compliant by default
- Full docs, automated tests, and CI/CD
- Modern stack: React, Node, AWS, PostgreSQL
- 8-12 week delivery guaranteed
Our proven process for B2B web apps
We follow a structured 4-phase approach that de-risks your project.
Phase 1 (Idea): We validate your core assumptions and prioritize features. In 5 working days we produce a product brief with user flows and data model.
Phase 2 (Roadmap): A detailed project plan with wireframes, tech stack recommendations, and a fixed quote. This phase costs $2.5K and is credited toward the build.
Phase 3 (Product): Our senior team builds the app in 8-12 weeks. We use 2-week sprints with daily standups and weekly demos.
Phase 4 (Release): We deploy to production, configure monitoring, provide hands-on training, and hand over full ownership.
