How IRPR Differs from Generic Dev Shops
You get senior engineers, fixed pricing, and full ownership.
Most agencies give vague estimates and assign junior developers. They hide scope creep in change orders and leave you with unmaintainable code.
IRPR gives you a fixed price after a 2-week Roadmap, senior engineers, CI/CD pipelines, and 30 days of post-launch support.
- Hourly billing with no cap
- Junior developers with little oversight
- No CI/CD pipeline
- Scope creep charged separately
- No post-launch support
- IP ownership unclear
- Fixed price after Roadmap phase
- Senior engineers only (7+ years experience)
- CI/CD on GitHub Actions from day one
- Fixed scope with clear change process
- 30-day post-launch support included
- Full IP ownership transferred
