Why startups choose IRPR as their experienced startup web app development partner
We have delivered 200+ web apps for startups worldwide.
Startups need speed and reliability. IRPR delivers both with a fixed-price model and a proven 4-phase process. Our senior engineers build with modern stacks like Next.js and Node.js.
Every project includes CI/CD, monitoring, and 30 days of post-launch support. You own the code from day one.
Generic agency vs experienced startup partner
Not all development shops understand startup timelines and budgets.
Many agencies bill by the hour and stretch timelines. IRPR gives you a fixed price and a clear roadmap in week 2.
We act as a true partner, not a vendor. Our senior engineers provide product feedback and technical guidance throughout the build.

- No fixed scope or timeline
- Uses outdated tech stacks
- No product strategy input
- Slow communication across time zones
- No post-launch support
- Fixed price from the start
- 8-12 week MVP delivery
- Modern stack: React, Node, AWS
- Product thinking from senior engineers
- Async-first, overlap hours daily
- Sentry monitoring + 30 days support
Our process for building your startup web app
We follow a proven 4-phase process: Idea, Roadmap, Product, Release.
Each phase has clear deliverables and milestones. You stay in control with weekly demos and a shared Slack channel.
The Roadmap phase (week 2) produces a detailed plan, fixed quote, and compliance audit. No ambiguity.
