Why choose IRPR as your startup software development firm
We are the best startup software development firm because we deliver fast, on budget, and with full ownership.
Every project starts with a 2-week Roadmap phase where we define scope, tech stack, and a fixed price. No hourly billing, no scope creep. You know the cost before we write a single line of code.
Our senior engineers have shipped 200+ products across 50 countries. 98% of projects are delivered on time. We integrate security and compliance from day one, not as an afterthought.
How we differ from other agencies
Most software firms bill hourly and hand you unfinished code. IRPR gives you a fixed price and production-ready software.
Generic dev shops start coding without a clear scope. They bill by the hour, extend timelines, and deliver code that needs rewriting. Startups lose months and budgets.
IRPR works differently. We define the entire product in a 2-week Roadmap, lock the price, then ship in 8-12 weeks. You get source code, CI/CD, and documentation from day one.
- Hourly billing with no cost cap
- Unclear timelines that slip by months
- No compliance or security planning
- Code owned by the agency
- No CI/CD or monitoring included
- Handoff without documentation
- Fixed price defined in Roadmap phase
- 8-12 week MVP delivery guaranteed
- HIPAA, PCI-DSS, SOC 2 built in
- Full source code ownership
- CI/CD pipeline on GitHub Actions
- Complete docs and runbooks
Our process for building startup software
We move from idea to production in four repeatable phases.
Each phase has a clear deliverable. You approve before we move forward. No surprises, no rework.
What you get when you work with IRPR
Everything needed to run and scale your startup software.
We don't just hand over code. We give you a production system that your team can operate from day one.

- Auth0 or Firebase authentication
- Sentry error tracking and monitoring
