Proven Results with B2B SaaS Development
Every project ships on time and on budget, with compliance built in from the start.
We have delivered over 200 B2B SaaS products for clients in 50 countries. Our average MVP timeline is 12 weeks, and 98% of projects launch on the date promised.
Our clients include early-stage founders who raised Series A after their MVP, and enterprises that reduced time-to-market by 60% compared to internal teams.
Why Choose IRPR Over a Generic Dev Shop
The difference shows in every line of code and every communication.
Most agencies sell you a team of junior developers who bill by the hour. You pay for their learning curve and end up with code you cannot scale.
IRPR assigns only senior engineers with 10+ years of B2B SaaS experience. We quote a fixed price in week 2 and deliver on that quote, period.
- Hourly billing with no cap
- Junior developers learning on your dime
- No dedicated project manager
- Code ownership unclear or shared
- No compliance expertise
- Handoff with zero support
- Fixed price from kickoff
- Senior engineers only (12+ years average)
- Dedicated PM with weekly demos
- Full source code ownership
- Built-in HIPAA / SOC 2 compliance
- 30-day post-launch support
Our B2B SaaS Development Process
Four phases from idea to production, each with clear deliverables and no surprises.
We start with a two-week Roadmap phase where we define features, tech stack, and fixed price. Then we build the MVP in eight weeks.
After QA and security testing, we deploy to production and monitor for 30 days. You own everything from day one.
What You Get in Every B2B SaaS Project
Every deliverable is designed to make your team self-sufficient after launch.
We do not just hand over code. We give you the infrastructure, documentation, and monitoring tools to run your SaaS without us.
All source code, config files, and credentials are placed in your GitHub repo. You control access and deployments from day one.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions + Docker
- Sentry error tracking configured
- PostgreSQL schema and migration files
- Stripe integration for payments
- AWS infrastructure as Terraform code
- Postman API collection with examples
- User documentation and admin guide
- Load testing report (1000 concurrent users)
- 30-day post-launch support
