Why IRPR is the best B2B web app development agency
We measure our success by your outcomes.
Our team has delivered over 200 B2B web applications across 50+ countries. Each project follows a proven process that keeps timelines short and quality high.
We focus on senior engineers only - no juniors, no outsourcing. This means your B2B app is built by developers with 10+ years of experience.
How we differ from generic development shops
Most agencies talk about quality. We deliver it with fixed pricing and senior talent.
Generic shops often assign junior developers to B2B projects, leading to rework and delays. They bill by the hour, so costs spiral.

- Junior developers on your project
- Hourly billing with no cap
- Unclear timelines
- No compliance expertise
- Code ownership unclear
- Slow communication
- Senior engineers only (10+ years)
- Fixed price from week 2
- 8-12 week delivery guaranteed
- Built-in HIPAA, SOC 2, PCI compliance
- You own all source code
