Results from our startup web app development
We have shipped over 200 web apps for startups across 50 countries.
Our senior engineers start every project with a two-week discovery phase. After that, we build a complete MVP in 8 to 12 weeks. You get full ownership of the source code and a CI/CD pipeline on GitHub Actions.
We maintain a 98% on-time delivery rate. Our fixed pricing model means the price at the start is the price you pay. No hourly billing, no scope creep charges.
How IRPR differs from generic dev shops
Most agencies lack the focus, experience, and transparency that startups need.
Generic development shops often start with vague estimates and junior developers. They bill by the hour, which leads to budget overruns and missed deadlines. Code ownership may be unclear, and post-launch support is usually an afterthought.
IRPR works differently. We assign only senior engineers who have built 10+ products each. Our fixed-price contract is set during the Roadmap phase in week 2. You own every line of code from day one.
- Vague estimates and hourly billing
- Junior developers learning on your project
- No code ownership guarantee
- Scope creep inflates the budget
- Unclear timeline with no accountability
- No post-launch support included
- Fixed price from day one
- Senior engineers only – average 10+ products each
- Full code ownership – you get everything
- Clear scope in the Roadmap phase
- 8-12 week delivery with weekly demos
- Ongoing support and maintenance available
Our 4-phase startup web app development process
We follow a repeatable framework: Idea, Roadmap, Product, Release.
Each phase has clear deliverables and a go/no-go decision point. This keeps the project on time and on budget. You are involved throughout.
The Roadmap phase costs a fixed $5,000 and takes one week. After that, we give you a fixed price for the full build. No surprises.

Every project includes everything you need to launch and grow.
You get a fully functional, production-ready web app with all source code. We configure CI/CD, error monitoring, and analytics from day one. No additional setup required.
Our standard stack includes Next.js, Tailwind CSS, Node.js, PostgreSQL, and Redis. We integrate Stripe, Auth0, and Sentry by default unless you prefer alternatives.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- Stripe payment integration (test mode live)
- Auth0 or Clerk authentication
- PostgreSQL database with migrations
- Docker containerization and docker-compose

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a single line of production code.
Senior engineers only
We assign developers who have built 10+ products each. No juniors, no offshore teams. Our engineers average 8 years of experience and work directly with you.
Full code ownership
You own everything we produce: source code, designs, documentation, and database schemas. We transfer all assets to your GitHub repository at launch. No licenses, no lock-in.
8-12 week delivery
We deliver a production-ready MVP in 8 to 12 weeks. Our process is optimized for speed without sacrificing quality. You see working software every week through a demo environment.
Post-launch support included
Every project comes with 30 days of post-launch support. We fix bugs, help with deployments, and advise on scaling. Optional extended maintenance is available at a fixed monthly rate.
Compliance ready
We build with compliance in mind. Our web apps support SOC 2, HIPAA, PCI-DSS, and FERPA requirements. We help you pass audits by implementing proper access controls, encryption, and logging.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
