Startup Web App Development by the Numbers
We track every build against real metrics so you know what to expect.
IRPR has shipped 200+ web applications for startups in 50 countries. Our average MVP takes 12 weeks from kickoff to production launch. 98% of projects deliver on time with no scope creep.
Our senior engineers have worked at companies like Google, Stripe, and AWS. They write clean code with 85%+ test coverage and deploy with CI/CD pipelines on GitHub Actions.
How We Build Startup Web Apps Differently
Most agencies pad hours and hand off code with no ownership. IRPR does the opposite.
Generic dev shops give you an hourly estimate and hope you approve more. They use junior developers who learn on your project. Code quality is often poor and you get locked into their hosting.
IRPR gives you a fixed price in week 2 during the Roadmap phase. Senior engineers with 10+ years experience build every line of code. You own the full source code from day one.
- Hourly billing with no price cap
- Junior developers doing most work
- No fixed timeline, scope changes
- Code not tested, missing CI/CD
- You don't own the repo initially
- Hard to switch vendors later
- Fixed price from roadmap phase
- Senior engineers only, 10+ years
- 12-week MVP timeline guaranteed
- Tests, CI/CD, monitoring included
- Full source code in your repo
- You can take the code anywhere
Our Process for Startup Web App Development
From idea to production in 12 weeks with four transparent phases.
We start with a 1-week Idea phase where we validate assumptions and define the core feature set. You pay nothing until the Roadmap is complete. In week 2 we deliver a fixed-price, fixed-scope plan.
The Product phase runs 8-10 weeks of active development. Engineers work in 2-week sprints with daily standups and weekly demos. The Release phase includes deployment, performance testing, and handoff.
What Ships With Every Startup Web App
Every project includes these production-ready deliverables by default.
We don't just give you code. We hand over a complete production system with monitoring, logs, and documentation. Your team can maintain it or we can continue to run it.
Everything is built in your own AWS or Vercel account from day one. No vendor lock-in, no hidden services.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite (unit, integration, e2e)
- Sentry error tracking and performance monitoring
- Stripe or custom payment integration
- Database schema with migrations (PostgreSQL)
- Deployment to AWS or Vercel
- Login system with Auth0 or Firebase Auth
- Admin dashboard with user management
- Technical documentation and runbook

Compliance by Default
All projects are built with HIPAA, PCI-DSS, and SOC 2 practices embedded from day one. We use encrypted databases, audit logs, and role-based access. No retrofitting compliance later.
Async-First Collaboration
We work across time zones with a 4-hour overlap with US hours. Use Slack, Linear, and Loom for updates. You get weekly video demos and a real-time dashboard of progress.
No Lock-In
You own the full source code, IP, and infrastructure from day one. We deploy to your AWS or Vercel account. You can take the code to another team any time without penalty.
Fast Kickoff
We can start the Idea phase within 2 business days of signing. Roadmap is delivered in week 2. Production development begins week 3. Most clients see a working prototype by week 4.
