Why startups choose a senior vendor
Our track record speaks for itself.
We have shipped over 200 web apps for startups across 50 countries. Our on-time delivery rate is 98%, and our average MVP timeline is 8-12 weeks.
Startups work with us because we deliver production-ready code, not prototypes. Every project includes CI/CD, error monitoring, and cloud infrastructure.
Generic dev shop vs senior vendor
Not all web app development vendors are equal.
Generic dev shops often assign junior developers to your project. They bill hourly and miss deadlines.
IRPR assigns senior engineers with 10+ years of experience. We work on a fixed price and deliver on time.
- Junior developers
- Hourly billing
- Scope creep
- No compliance expertise
- Long timelines
- No post-launch support
- Senior engineers only
- Fixed price from day one
- Clear scope in 2-week roadmap
- HIPAA/PCI/SOC 2 ready
- 8-12 week MVPs
- Sentry + CI/CD included
