Why Choose IRPR as Your B2B SaaS Development Agency
We have shipped over 200 B2B SaaS products for companies in 50+ countries.
Every project starts with a 2-week Roadmap phase where we define the architecture, data model, and feature list. You get a fixed price and timeline before any code is written. No surprises.
Our senior engineers work in small teams of 3-5 people. We use React or Next.js for the frontend, Node.js or Python for the backend, and PostgreSQL or MongoDB for data. Every deployment uses Docker and runs on AWS or GCP.
How We Build B2B SaaS Products Differently
Most agencies overpromise and underdeliver. We don't.
Generic dev shops often start coding without a clear plan. They use hourly billing and change scope constantly. You end up with a messy codebase and no timeline.
IRPR uses a fixed-price model based on a detailed Roadmap. We build with testing from day one and deploy to production by week 10. You own the code, the IP, and the infrastructure.
- Hourly billing with no cap
- Scope creep without change orders
- Junior developers learning on your project
- No compliance or security review
- Code delivered without tests
- No deployment or monitoring setup
- Fixed price from the Roadmap phase
- Scope locked before development starts
- Senior engineers with 10+ years experience
- SOC 2, HIPAA, PCI-DSS compliance built in
- Unit tests, integration tests, and CI/CD pipeline
- Docker, Kubernetes, and Sentry monitoring
Our B2B SaaS Development Process
Four phases from idea to release. Each phase has a clear deliverable.
Phase 1 is the Idea phase where we validate your concept and define the target audience. Phase 2 is the Roadmap phase where we produce a detailed technical specification and fixed price.
Phase 3 is the Product phase where we build the MVP in 8-12 weeks. Phase 4 is the Release phase where we deploy to production and set up monitoring. Total timeline is typically 10-14 weeks.
