IRPR builds B2B SaaS platforms using React, Node.js, PostgreSQL, and AWS. We ship multi-tenant architectures with Stripe billing, Auth0 authentication, and Datadog monitoring from day one.
Every project starts with a 2-week Roadmap phase for a fixed fee of $8K. Full MVP builds run 8-12 weeks and cost $80K-$250K. All code is owned by you and deployed on your AWS account with SOC 2 controls.
We work with SaaS founders who need a technical co-founder, CTOs scaling their platform, product managers launching new features, and enterprise teams building internal SaaS tools.

Why choose IRPR for B2B SaaS development
We deliver production-ready SaaS platforms with enterprise compliance and fixed pricing.
IRPR has shipped over 200 SaaS products across 50 countries. Every project uses a repeatable framework: Idea, Roadmap, Product, Release. The Roadmap phase costs $8K and takes 2 weeks. You get a detailed spec, architecture diagram, and fixed price quote before any development begins.
Our senior engineers have built SaaS platforms handling millions of API calls per day. We use AWS ECS for containerized deployments, PostgreSQL for multi-tenant data, and Stripe for billing. All projects include CI/CD pipelines, automated testing, and 99.9% uptime SLAs.
How IRPR differs from generic development shops
Most agencies treat B2B SaaS like any other web app. We don't.
Generic shops build single-tenant apps and bolt on multi-tenancy later. That creates data leaks, scaling issues, and expensive rewrites. IRPR builds multi-tenant architecture from the first commit using row-level security in PostgreSQL and isolated compute on AWS.
We also include SOC 2 controls by default - audit logging, encryption at rest, and access controls. Your platform is ready for enterprise sales from day one. No retrofitting compliance after launch.
- Single-tenant codebase that requires rewrites
- No compliance framework until after launch
- Hourly billing with scope creep
- Junior developers on your project
- No CI/CD or monitoring by default
- Code ownership often unclear
- Multi-tenant from day one with row-level security
- SOC 2, HIPAA, PCI-DSS built in
- Fixed price after 2-week Roadmap
- Senior engineers only (8+ years average)
- CI/CD, Sentry, Datadog included
- Full code ownership, deployed on your AWS
Our B2B SaaS development process
From idea to production in 8-12 weeks. Here's how.
Every project follows IRPR's four-phase framework. The Roadmap phase is the most important - we spend 2 weeks understanding your market, users, and technical requirements. You get a working prototype and a fixed price before any development starts.
During the Product phase, we build in 2-week sprints with daily standups and weekly demos. The Release phase includes load testing, security audit, and deployment to production. We provide 30 days of post-launch support.
What ships with every B2B SaaS project
You don't just get code. You get a production-ready platform.
Every project includes the infrastructure and tooling needed to run a SaaS business. We set up Stripe billing with multiple pricing models, Auth0 for authentication and SSO, and Datadog for monitoring. All code is deployed on your AWS account with IAM roles and encryption at rest.
We also include a developer handbook that explains how to maintain and extend the platform. Your team can take over immediately or we can continue with a retainer.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Stripe integration with subscription and invoicing
- Auth0 authentication with social login and SSO
- PostgreSQL database with row-level security for multi-tenancy
- Docker containers deployed on AWS ECS with auto-scaling
- Sentry error tracking and Datadog monitoring dashboards
- Load testing report with 99.9% uptime verification
- Developer handbook with architecture docs and runbooks
- 30 days of post-launch support and bug fixes
