Why choose an expert startup web app development firm?
Speed and quality matter when you are building your first product.
IRPR has shipped over 200 products for startups in 50+ countries. Every project uses senior engineers only, no junior talent. You get a fixed price quote after a 2-week Roadmap phase.
Our MVPs go live in 8-12 weeks. We use React, Node.js, Python, and AWS. You own the code and all IP. No lock-in, no hidden fees.
How IRPR differs from other development agencies
Most agencies sell you an hourly rate and a loose estimate. We do the opposite.
Generic dev shops often assign junior developers, change scope mid-project, and surprise you with overtime invoices. IRPR works differently.
We assign senior engineers only, give you a fixed price at week 2, and deliver on time. Our process is transparent and built for startups that need to launch fast.

- Hourly billing with no cap
- Junior developers learning on your project
- No compliance expertise
- Slow communication and delays
- No post-launch support contract
- Fixed price after a 2-week roadmapping phase
- Senior-only engineers with 10+ years experience
- Compliance built-in: SOC 2, HIPAA, PCI-DSS
- Dedicated project manager with daily standups
- MVPs delivered in 8-12 weeks on average
- 1-year warranty on all code shipped
Our process for building your startup web app
From idea to launch in four clear phases.
We start with a 2-week Roadmap phase where we define scope, tech stack, and fixed price. No guessing, no surprise costs.
Then we build your MVP in 8-12 weeks using React, Node.js, and AWS. You get weekly demos, a staging environment, and full code ownership.
What you own when we build your web app
Full ownership. No code locks, no platform dependency.
When IRPR builds your startup web app, you own everything. Source code, database schema, API keys, documentation. We just hand it over.
We set up your own cloud accounts (AWS, Stripe, GitHub). You control access. We never hold your code hostage.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Staging and production environments on AWS
- Sentry error tracking
- Datadog performance monitoring
- Postman API documentation
- Architecture diagrams and README
- Admin panel for managing users and data
- 1-year code warranty (bug fixes)
