Why IRPR is the best B2B SaaS development agency for your next product
We have shipped over 200 B2B SaaS products across 50 countries with a 98% on-time delivery rate.
Our senior engineers average 10+ years of experience building multi-tenant SaaS platforms. We use React for the frontend, Node.js or Python for the backend, and PostgreSQL for data. Every deployment runs on AWS with Docker and Kubernetes for scalability.
We do not use junior developers or offshore teams. Every IRPR project has one lead engineer who writes all the code and reviews everything. This keeps quality high and communication direct. You talk to the person building your product.
What makes IRPR different from other B2B SaaS development agencies
Most agencies bill by the hour and change scope. IRPR gives you a fixed price and a fixed timeline.
We start every project with a 2-week Roadmap phase. In those 2 weeks we define the full scope, tech stack, and architecture. You get a fixed quote for the entire build. No hourly billing, no scope creep, no surprise invoices.
After the Roadmap phase, we build the MVP in 8-12 weeks. You get daily updates in Slack, weekly demos, and full access to the code repository. When we ship, you own everything: source code, documentation, CI/CD pipeline, and cloud infrastructure.
- Hourly billing that encourages slow work
- Junior developers learning on your project
- No fixed scope or timeline
- Code you may not own fully
- Poor documentation and handoff
- No compliance expertise
- Fixed price agreed in week 2
- Senior engineers with 10+ years experience
- 8-12 week MVP with clear milestones
- Full source code ownership
- Complete documentation and CI/CD pipeline
- SOC 2, HIPAA, PCI-DSS built in
Our B2B SaaS development process from idea to launch
We follow a 4-phase process that takes you from idea to production in 8-12 weeks.
Phase 1 is the Idea validation. We review your concept, market, and technical feasibility in a 1-week sprint. You get a clear yes or no on whether the idea is buildable and what the risks are.
Phase 2 is the Roadmap. We spend 2 weeks defining the user stories, data model, API contracts, and UI mockups. You get a fixed price quote and a detailed timeline. Phase 3 is the Build: 8-12 weeks of development with weekly demos. Phase 4 is the Release: we deploy to production, set up monitoring with Sentry and Datadog, and hand over the keys.
What ships with every B2B SaaS product from IRPR
Every B2B SaaS we build comes with a complete production-ready package, not just code.
You get more than a working app. We ship the entire infrastructure: CI/CD pipeline with GitHub Actions, monitoring with Sentry and Datadog, error tracking, and automated testing. Your team can start maintaining the product on day one without needing to reverse-engineer anything.
We also include a deployment playbook, architecture diagram, API documentation (OpenAPI), and a runbook for common tasks. If you need to add features later, you can hand the project to any developer and they will understand it in hours, not weeks.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Deployment on AWS with Docker and Kubernetes
- Sentry error monitoring and Datadog performance tracking
- OpenAPI documentation for all endpoints
- Architecture diagram and runbook
- Automated test suite (unit, integration, e2e)
- Admin dashboard with user management and billing controls
- Stripe or Chargebee integration for subscriptions
- Full ownership transfer with no licensing restrictions
