Why Startups Choose IRPR for Web App Development
We have shipped over 200 web apps for startups across 50 countries.
Our senior engineers average 10+ years of experience. Every project starts with a 2-week Roadmap phase where we define scope, tech stack, and a fixed price. No hourly billing, no scope creep.
Startups that work with IRPR go from idea to launch in 8-12 weeks. We handle everything from frontend to DevOps. You own the source code from day one.
How IRPR Delivers Better Startup Web Apps
Most agencies overpromise and underdeliver. We do the opposite.
Generic dev shops assign junior developers and bill by the hour. They change requirements without telling you. You end up with a half-finished app and a bloated invoice.
IRPR assigns senior engineers only. We give you a fixed price after the Roadmap phase. You see progress every week. No surprises, no excuses.
- Junior developers learning on your project
- Hourly billing with no cap
- Scope creep without change orders
- No dedicated project manager
- Code quality issues and tech debt
- You don't own the code until paid in full
- Senior engineers with 10+ years experience
- Fixed price after 2-week Roadmap
- Scope locked in Roadmap, changes quoted separately
- Dedicated project manager and weekly demos
- Code reviews, automated tests, CI/CD
- You own the source code from day one
Our Process for Building Startup Web Apps
From idea to launch in 8-12 weeks. Here are the steps.
We follow a proven four-phase process. Each phase ends with a clear deliverable. You always know what's coming next.
The Roadmap phase costs $5K-$15K and covers architecture, tech stack, user stories, and a fixed price quote. After that, we build and ship your web app.

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
We don't hire juniors. Every engineer on your project has 10+ years of experience and has shipped at least 5 production web apps. You get a tech lead, not a trainee.
8-12 week MVP delivery
From kickoff to production launch in 8-12 weeks. We use proven frameworks and pre-built components to accelerate development without sacrificing quality.
You own the code
Source code is in your GitHub repo from day one. You own all intellectual property. No licensing fees, no vendor lock-in. You can take the code anywhere.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the architecture from the start. No costly retrofits. We have completed 15+ compliance audits for clients.
Post-launch support included
After launch, we provide 30 days of free support: bug fixes, monitoring, and documentation. We also offer ongoing maintenance retainers starting at $5K/month.
