Why startups choose IRPR for web app development
We build production-grade web apps that launch fast and scale without rewrites.
Startups need speed and reliability. IRPR delivers both. With 200+ products shipped across 50+ countries, we have a repeatable process that cuts risk. Our average delivery is 12 weeks, and 98% of projects finish on time.
Every app runs on AWS with auto-scaling, Sentry error tracking, and CI/CD pipelines. We use React and Next.js for the frontend, Node.js for the backend, and PostgreSQL for data. No legacy code, no technical debt.
IRPR vs generic dev shops
Most agencies bill hourly and change scope. We fixed that.
Generic dev shops start with hourly estimates that balloon. They assign junior developers and skip compliance. You end up with code you don't own and a product that breaks after launch.
IRPR works differently. We give you a fixed price after a 2-week roadmap. Senior engineers only. Full code ownership. Compliance built in from week one. And we include post-launch support.
- Hourly billing with no cap
- Scope changes mid-project
- Junior developers on your account
- No compliance expertise
- Code stays with the agency
- No CI/CD or monitoring
- Fixed price after 2-week roadmap
- Scope locked in Roadmap phase
- Senior engineers only (avg 10+ years)
- HIPAA, PCI, SOC 2 ready
- Full code ownership in your repo
- CI/CD, Sentry, AWS included
Our process for building your startup web app
We break the project into four phases so you always know what you get and when.
Every engagement starts with a 2-week Roadmap phase where we define scope, tech stack, and a fixed price. No surprises. Then we design, build, and launch in sprints.
You get regular demos, a staging environment, and a clear launch checklist. Post-launch we handle monitoring and fixes for 30 days.
What ships with your startup web app
Every project delivers a complete production system, not just code.
You get everything needed to run and grow your app. No hidden dependencies. No vendor lock-in.
We set up your AWS infrastructure, CI/CD pipeline, error tracking, and analytics. Your team can take over immediately.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking with alerts
- AWS infrastructure as code (Terraform)
- Automated test suite (Jest, Cypress)
- Admin dashboard for your team
- API documentation (Swagger/OpenAPI)
- User authentication (Auth0 or custom)
- Payment integration (Stripe or Braintree)
- Google Analytics or Mixpanel setup

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team averages 10+ years of experience. No junior developers. Every engineer has shipped production apps at scale.
Compliance built in from day one
We handle HIPAA, PCI-DSS, and SOC 2 requirements during the Roadmap phase. No retroactive security fixes.
Full code ownership
You own all source code, infrastructure config, and IP from day one. We push code to your GitHub repo, not ours.
2-week roadmap locks scope
We spend the first 2 weeks defining exactly what you get. After that, the scope and price are fixed. No changes mid-build.
Post-launch support included
Every project includes 30 days of monitoring, bug fixes, and deployment support after launch. We don't disappear after delivery.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
