Why Startups Choose IRPR for Web App Development
We ship fast without cutting corners.
IRPR has shipped over 200 web apps for startups in 50+ countries. Our average MVP timeline is 10 weeks, and 98% of projects deliver on schedule.
We use a fixed-price model that eliminates budget surprises. Every project starts with a 2-week Roadmap that defines scope, price, and timeline before any development begins.
How We Differ from Generic Development Agencies
Most agencies bill hourly and change scope. We don't.
Generic agencies often start with a vague estimate and a battle over scope creep. IRPR defines everything up front in a Roadmap deliverable.
Our clients know the exact cost, timeline, and deliverables before a single line of code is written. We then execute in 2-week sprints with daily updates.
- Hourly billing with no cap
- Scope creep inflates budgets
- No compliance knowledge
- Unclear timeline commitments
- You don't own the source code
- Communication via email only
- Fixed price per project
- Scope defined in 2-week Roadmap
- HIPAA, PCI-DSS, SOC 2 ready
- 8-12 week delivery promise
- Full code ownership on day one
- Daily standups in your Slack
Our Web App Development Process (12 Weeks)
From idea to production in 12 weeks flat.
We break every project into four phases. Each phase produces a concrete deliverable that you can see and test.
By the end of week 12, your web app is live on a production server with CI/CD, monitoring, and full documentation.
What Ships with Every Web App
You get more than code. You get a complete launch package.
When IRPR delivers your web app, you receive everything needed to run it in production. No missing pieces, no unplanned work.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Deployed to AWS or GCP
- SSL certificate and DNS setup
- Sentry error tracking configured
- PostgreSQL database with backups
- User authentication (Auth0 or Firebase)
- Stripe payment integration
