We ship your web app MVP in 8-12 weeks for a fixed price. No hourly billing, no surprises.
IRPR builds startup web apps using React, Next.js, Node.js, Python, and AWS. We focus on getting your first product out fast, not over-engineering.
Our standard timeline is 8-12 weeks from idea to launch. Pricing starts at $80K and goes to $250K, all fixed before we write a line of code. We cover compliance like HIPAA, PCI-DSS, and SOC 2 as needed.
Founders with a validated idea hire us to build their MVP. Product managers at funded startups need a senior team to ship their roadmap. CTOs who want to avoid technical debt bring us in to build a solid foundation. We also work with corporate innovation labs launching new ventures.

Why Startups Choose IRPR for Web App Development
We deliver production-grade web apps in 8-12 weeks with fixed pricing and full code ownership.
IRPR has shipped over 200 web apps for startups in 50 countries. Every project starts with a two-week roadmap phase where we define the exact scope, tech stack, and timeline. After that, we lock the price and build in 8-12 weeks.
Our senior engineers work directly with your team. No junior devs, no offshore mills. We use React, Next.js, Node.js, Python, and deploy on AWS or GCP. Every project includes CI/CD, monitoring, and error tracking from day one.
The IRPR Difference
We build startup web apps differently: fixed price, senior engineers, and no surprises.
Most agencies charge by the hour and change scope mid-project. That leaves startups with unpredictable costs and delayed launches. IRPR takes a different approach: we scope everything in a two-week roadmap, then give you a fixed price.
You get a dedicated team of senior engineers who have built apps for fintech, healthcare, and SaaS companies. We handle compliance (HIPAA, PCI-DSS, SOC 2) when you need it. And you own all the code and infrastructure from day one.
- Hourly billing with no cap
- Junior developers assigned
- Scope creep without price change
- No compliance expertise
- You don't own the code
- 6+ months to MVP
- Fixed price from week 2
- Senior engineers only (10+ years)
- Scope defined in roadmap, locked
- HIPAA/PCI/SOC 2 built in
- Full code ownership
- 8-12 weeks to MVP
How We Build Your Startup Web App
Four phases from idea to launch with clear milestones and weekly demos.
We break every project into four phases: Idea, Roadmap, Product, Release. Each phase has a defined output and timeline. You see real progress every week.
During the Idea phase we align on product goals. In Roadmap we define the MVP scope, tech stack, and fixed price. Product phase is where we build in sprints. Release covers deployment, testing, and handoff.
What Ships with Your Startup Web App
You get more than code. Every project includes these production-ready items.
IRPR doesn't just hand over a codebase. We ship a fully deployable application with all the tooling a startup needs to operate. No hidden dependencies or manual setup.
Everything is documented and ready for your team to extend. You own all assets, including domain registration, cloud accounts, and source code repositories.
