Why IRPR outperforms typical startup development shops
Most agencies say they deliver fast. We show you the difference.
Generic app developers often bid by the hour, change scope mid-project, and hand over code with no documentation. That kills startup velocity.
IRPR runs a structured 4-phase process: Idea validation, Roadmap with fixed quote, sprint-based MVP build, and a release that includes CI/CD and monitoring. Every client owns their source code from day one.
- Hourly billing with unpredictable total
- No upfront discovery or roadmap
- Junior developers on your project
- No CI/CD or monitoring setup
- Code ownership often unclear
- Post-launch support is extra cost
- Fixed price from the Roadmap phase
- Structured discovery with detailed spec
- Senior engineers with 10+ years experience
- CI/CD pipeline, Sentry, and logs included
- Full code ownership in your GitHub repo
- 2 months of post-launch support included
How we build your startup web app in 12 weeks
Our 4-phase process removes guesswork and delivers a production-ready MVP fast.
Phase 1 (Idea) takes 1-2 weeks. We validate assumptions, review competitors, and write user stories. Phase 2 (Roadmap) produces a fixed-price quote with a detailed technical spec and wireframes.
Phase 3 (Product) is 6-8 weeks of 2-week sprints. You see a working app each sprint. Phase 4 (Release) deploys to AWS or Fly.io with CI/CD, monitoring, and a 30-day warranty.
What you get when you hire the best startup web app development firm
