IRPR vs. Generic Development Shops
The top startup web app development agency delivers different results.
Generic agencies treat every project the same. They use junior developers, hourly billing, and vague timelines. Startups often get half-finished products that don't scale.
IRPR assigns senior engineers only, uses fixed pricing, and ships production code with CI/CD, monitoring, and documentation. Your MVP is ready to launch on day 1 of testing.
- Uses junior or offshore developers
- Hourly billing ($150-$250/hr)
- Unclear timeline (4-6 months typical)
- No compliance knowledge (HIPAA, PCI)
- Code ownership disputed after project
- No post-launch support plan
- Senior engineers only (10+ years average)
- Fixed price bid in Roadmap phase
- 8-12 week delivery guarantee
- Built-in compliance for healthcare, finance, SaaS
- Full source code ownership from day one
- Included monitoring, error tracking, and 30-day warranty
