Why hire a senior startup web app development firm?
IRPR has the track record and processes to launch your product fast.
We have shipped over 200 web apps for startups across 50+ countries. Every project is built by a senior engineering team with 10+ years average experience.
Our process eliminates guesswork. You get a fixed price, predictable timeline, and a product that handles production traffic from day one.
The difference between a generic agency and a senior startup web app development firm.
Most agencies assign junior developers or outsource. IRPR gives you a team of senior engineers.
Generic agencies often use hourly billing and junior talent, leading to scope creep and delays. They lack compliance knowledge and may not include CI/CD or monitoring by default.
IRPR is built for startups. We assign only senior engineers, fix the price upfront, and include compliance, CI/CD, and full code ownership in every engagement.
- Uses hourly billing
- Assigns junior devs
- No compliance knowledge
- No CI/CD by default
- Code ownership unclear
- Delays common
- Fixed price from roadmap
- Senior engineers only (7+ years avg)
- HIPAA/PCI/SOC2 from day one
- CI/CD and monitoring included
- Full code ownership
- On-time delivery guarantee
How we build your startup web app in 8-12 weeks.
Our process from idea to launch is transparent and predictable.
We start with a two-week discovery phase to define scope, architecture, and a fixed price. Then we move into design, development, and launch sprints.
Every sprint includes a demo, and you have full visibility into progress through our shared project management tools.
What ships with every web app engagement.
We deliver a complete product, not just code.
Every project includes a production-ready deployment, monitoring, and documentation. You get everything needed to run and maintain your web app.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Deployed to AWS/GCP with Terraform
- Sentry error tracking
- Datadog monitoring dashboard
- Database schema and migration files
- API documentation (Swagger)
- User documentation
