Leading Startup Web App Development AgencyWeb App
We ship production-ready web apps in 8-12 weeks. 200+ products delivered across 50+ countries.
IRPR is a leading startup web app development agency. We build with React, Next.js, Node.js, and PostgreSQL — the same stack used by high-growth startups. Every app ships with CI/CD, Sentry error tracking, and automated testing from day one.
Our typical engagement is 8-12 weeks with fixed pricing from $80,000 to $250,000. You own the source code, the infrastructure, and all intellectual property. No ongoing royalties, no vendor lock-in.
We work with funded seed-stage startups, bootstrapped SaaS founders, enterprise innovation labs launching new products, and product managers who need an experienced engineering team without hiring full-time.

Why Startups Choose IRPR for Web App Development
We have built over 200 web apps for startups. Here is what that experience delivers.
Every startup has unique constraints: limited runway, aggressive timelines, and the need to iterate fast. IRPR aligns with that reality. We use a 4-phase framework: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we give you a fixed price and a detailed technical specification — no surprises.
Our senior engineers have built products used by millions of users. They know when to use Next.js vs. Remix, when to choose PostgreSQL over MongoDB, and how to set up infrastructure that scales from 100 to 100,000 users without rewrites. We also handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2).
How IRPR Differs from Other Development Agencies
Most agencies charge by the hour and change scope. IRPR does things differently.
The standard agency model: you pay a deposit, the team starts building, and the scope grows every week. By week 10 you have overspent and still no working product. That does not work for startups.
IRPR works on fixed price with a clear specification from week 2. You know exactly what you get and what it costs. We ship in 8-12 weeks, not 6 months. And we stay available for post-launch iterations at a predictable rate.
- Hourly billing with no cap
- Scope creep every sprint
- Junior developers on your project
- No compliance expertise
- No CI/CD pipeline by default
- Vague delivery timelines
- Fixed price from week 2
- Scope locked in Roadmap phase
- Senior engineers only (15+ years avg)
- HIPAA, PCI-DSS, SOC 2 ready
- CI/CD, Sentry, automated tests included
- 8-12 week delivery guarantee
Our 4-Phase Framework for Startup Web Apps
From idea to launch in 8-12 weeks. Here is how we do it.
Our framework is designed to eliminate uncertainty. Each phase has a clear deliverable and a go/no-go decision point. You can pause after any phase without penalty.
Phase 1 (Idea) is a 1-week deep dive on your market and user needs. Phase 2 (Roadmap) produces a detailed spec and fixed price. Phase 3 (Product) is a 6-10 week build sprint. Phase 4 (Release) deploys to production with monitoring and documentation.
What Ships in Every Startup Web App Engagement
You are not just getting an app. You get everything needed to launch and grow.
- Full source code in your GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Automated deployment to AWS, GCP, or Azure
- Sentry error tracking and performance monitoring
- PostgreSQL database with automated backups
- Stripe or Braintree payment integration (if applicable)
- Comprehensive API documentation (OpenAPI/Swagger)
- Load testing results (k6 or Artillery)
- Admin dashboard for user management and reporting
- Deployment runbook for your operations team
