We build your MVP in 8-12 weeks with a fixed price. Senior engineers only, no junior devs.
IRPR is a group of senior software engineers who act as top startup software development consultants. We use React, Next.js, Node.js, Python, and AWS to turn your idea into a working product fast.
We deliver a production-ready MVP in 8-12 weeks at a fixed price between $80K and $250K. Every project meets compliance standards like HIPAA, PCI-DSS, or SOC 2 if needed.
Founders with a validated idea hire us to build their first product. CTOs bring us in to scale a complex feature. Product managers use us to replace a broken legacy system. Investor-backed startups trust us to hit their demo deadlines.

What Top Startup Software Development Consultants Deliver
We don't just write code. We ship working software with measurable results.
Every project starts with a detailed roadmap. In week 2 you get a fixed quote, a timeline, and a list of features. No surprises.
We use React, Node.js, PostgreSQL, and AWS for most projects. For AI work we add OpenAI and LangChain. For mobile we use React Native or Flutter.
Why Startups Choose IRPR Over Generic Dev Shops
Most agencies promise everything but deliver little. We do the opposite.
Generic dev shops assign your project to junior developers with minimal oversight. They charge by the hour, so scope creep becomes their profit.
IRPR assigns only senior engineers with 10+ years of experience. We give you a fixed price upfront and a single point of contact who writes code.
- Junior devs with <3 years experience
- Hourly billing with no cap
- No fixed timeline or scope
- Code quality drops as budget runs out
- No compliance knowledge
- You own nothing until final payment
- Senior engineers only (10+ years)
- Fixed price from week 2
- 8-12 week timeline guaranteed
- CI/CD and code review on day one
- HIPAA, PCI, SOC 2 experience
- Full IP ownership from kickoff
How Our Startup Software Development Process Works
Four phases from idea to release. No hand-holding, just results.
We keep meetings to one 30-minute standup per week. Everything else happens in Slack and Notion.
You get a demo every two weeks. The first demo shows real working code, not mockups.
What Ships With Every MVP
No black boxes. Everything is yours from day one.
We transfer the entire codebase, infrastructure config, and documentation at launch.
You can run the product yourself or continue working with us for post-launch features.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Infrastructure as code (Terraform)
- Sentry error tracking
- Log management (Datadog or CloudWatch)
- User authentication (Auth0 or Firebase)
- Admin dashboard with user management
- API documentation (Swagger)
- Unit and integration tests
- Deployment runbook

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.
Senior engineers only
Every engineer has 10+ years of experience. We never hire juniors. Your code is written by people who have shipped production systems at scale.
8-12 week MVP guaranteed
We target 8-12 weeks for every MVP. Our average is 12 weeks across 200+ projects. Every project has a concrete timeline and you see progress every 2 weeks.
Full code ownership from kickoff
You own the source code, infrastructure config, and IP from day one. There are no licensing fees or vendor lock-in.
Compliance built-in
We have shipped products for healthcare (HIPAA), fintech (PCI-DSS), and enterprise (SOC 2). Compliance is part of the architecture, not an afterthought.
Async-first, aligned timezones
We work distributed-first with overlap in US timezones (EST, CST, PST). You get daily async updates in Slack and a weekly 30-minute call.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
