How We Differ from Generic Dev Shops
Most dev shops bill hourly and miss deadlines. IRPR does the opposite.
Generic agencies often lack SaaS-specific experience. They treat every project like a custom website. We build multi-tenant architectures, subscription billing, and compliance from day one.
IRPR assigns a senior product manager and a lead engineer to every project. We use weekly demos, not status emails. You see working code every Friday.
- Hourly billing with no budget cap
- Junior developers on your project
- No product strategy or roadmap
- Handoff at launch, no ongoing support
- No compliance experience (HIPAA, SOC 2)
- Unclear IP ownership
- Fixed price for each phase (Roadmap, Build, Release)
- Senior engineers only - average 8+ years experience
- Included product strategy and roadmap in week 2
- Post-launch support and maintenance plans available
- Built-in compliance for HIPAA, SOC 2, PCI-DSS
- You own all source code and infrastructure
Our 4-Phase SaaS Development Process
From idea to production in a predictable timeline. Each phase has clear outputs and fixed pricing.
Phase 1 (Idea) takes 1 week. We define your target user, core features, and technical feasibility. Phase 2 (Roadmap) takes 1 week and produces a full product specification, wireframes, and a fixed price quote.
Phase 3 (Product) runs 8-12 weeks. Our team builds the MVP using CI/CD with GitHub Actions and deploys to staging every week. Phase 4 (Release) handles production deployment, monitoring with Sentry and Datadog, and user onboarding.
What Ships with Every B2B SaaS Project
You receive a production-ready SaaS platform with all the operational tools included.
Every project includes source code in your GitHub repository, CI/CD pipelines, and infrastructure as code (Terraform). We also set up logging, error tracking, and performance monitoring out of the box.
You get a deployed staging environment within the first two sprints. We use AWS Amplify or AWS ECS for hosting, depending on your scale.
- Source code in your GitHub repository (full ownership)
- CI/CD pipeline via GitHub Actions
- Infrastructure as code with Terraform
- Staging environment on AWS (or GCP/Azure)
- Error tracking with Sentry
- Performance monitoring with Datadog
- User authentication via Auth0 (SSO, MFA)
- API documentation (Postman collection or Swagger)
- HIPAA / SOC 2 compliance evidence package
