Why Choose a Leading B2B SaaS Development Agency Like IRPR
We deliver production-ready platforms that scale from day one.
Every B2B SaaS project starts with a 2-week Roadmap phase where we define the full architecture, data model, and API contract. We use AWS CDK for infrastructure-as-code and deploy on Kubernetes with auto-scaling.
Our team ships code to production every sprint. You get a working demo at week 4. By week 12 you have a compliant, tested platform ready for your first 100 customers.
The Difference Between Generic Dev Shops and a B2B SaaS Specialist
Most agencies sell web apps. IRPR sells SaaS platforms built to scale.
Generic dev shops start coding without a roadmap. They use hourly billing, switch engineers mid-project, and ignore compliance until launch day. You end up with technical debt and surprise bills.
IRPR engineers have built 200+ SaaS platforms. We write multi-tenant code from the first commit, enforce SOC 2 controls through automated pipelines, and deliver on a fixed price and timeline.
- Hourly billing with no cap
- Junior developers learning on your project
- No compliance review until launch
- Single-tenant architecture bolted on later
- No CI/CD pipeline
- Source code license restricted
- Fixed price agreed in week 2
- Senior engineers only, 10+ years experience
- SOC 2 controls built into every PR
- Multi-tenant from the first database schema
- GitHub Actions CI/CD deployed at week 1
- Full IP ownership, no royalties
Our SaaS Development Process: From Idea to Production
We follow a proven 4-phase framework designed for B2B SaaS.
Each phase has clear deliverables and a fixed budget. You never pay for discovery or rework. The process works for startups, scaleups, and enterprises alike.
We have shipped platforms for healthcare, fintech, and logistics clients. Every project passes our internal security audit before release.
What Ships with Every B2B SaaS Platform
You own everything we build. There are no licensing fees or ongoing obligations.
Our delivery includes production-ready code, automated infrastructure, and full documentation. Every project is built to be maintained by your team or ours.
