Expert B2B SaaS Development Vendor Delivers Predictable Results
We have shipped over 200 B2B products and have a 98% on-time delivery rate.
Our team of senior engineers follows a proven process: Idea, Roadmap, Product, Release. Each phase has clear milestones and fixed pricing. We do not use hourly billing or change orders.
From fintech to healthcare, our SaaS platforms hold SOC 2 Type II reports and pass HIPAA audits. We build with compliance from day one, not as an afterthought.
Why Generic Dev Shops Fail at B2B SaaS
Most agencies overpromise and underdeliver on B2B SaaS projects. Here is the real difference.
Generic shops often use junior developers, change requirements mid-project, and hand over code without documentation or CI/CD. That leads to buggy launches and technical debt.
IRPR assigns only senior engineers, locks scope after the Roadmap phase, and ships a production-ready SaaS with monitoring, error tracking, and full documentation.
- Junior or offshore developers
- Hourly billing with overruns
- No compliance experience
- Code without tests or CI/CD
- Delayed deliveries (6-12 months)
- No post-launch support
- Senior engineers only (10+ years avg)
- Fixed price after Roadmap phase
- SOC 2, HIPAA, PCI-DSS built in
- 100% test coverage, GitHub Actions CI/CD
- 8-12 week MVP timelines
- Sentry, Datadog, and 30-day support included
Our SaaS Development Process: From Idea to Release
Four phases that turn your concept into a live, compliant B2B SaaS product.
Every project follows the same framework: Idea, Roadmap, Product, Release. We start with a discovery sprint to validate your vision and end with a deployed, monitored application.
The Roadmap phase produces a fixed-price proposal with detailed technical specifications. Once approved, the team executes in 2-week sprints with daily standups and continuous delivery.

Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before a single line of code is written.
Senior engineers only
Our team averages 12+ years of experience. No juniors. No offshore body shops. Each engineer has shipped multiple B2B SaaS products and holds current AWS certifications.
8-12 week MVPs
We deliver a working, deployed MVP in 8-12 weeks - not 6 months. Our process is optimized for speed without sacrificing compliance or code quality.
Full code ownership
You own every line of code from day one. We put the source code in your private GitHub repository. No licensing fees, no hidden dependencies.
Compliance built in
We build SOC 2, HIPAA, and PCI-DSS compliant SaaS from the start. Our deployments pass audits because security is hardcoded into the architecture, not bolted on later.
99.9% uptime SLA
We deploy on AWS with auto-scaling, multi-AZ configurations, and redundant databases. Our monitoring stack (Datadog, PagerDuty) alerts the team before users notice an issue.
