Why Choose a Senior B2B SaaS Development Vendor
IRPR has shipped 200+ B2B SaaS products for clients in 50+ countries since 2016.
We focus on senior engineers only. Every developer has 10+ years of experience. No juniors, no outsourcing. You talk directly to the team building your product.
Our process starts with a 2-week Roadmap phase where we define scope, architecture, and fixed price. After that we build your MVP in 8-12 weeks. You own 100% of the code.
How We Differ from Other Vendors
Most dev shops rely on junior talent and hourly billing. IRPR works the opposite way.
We are a senior B2B SaaS development vendor that hires only experienced engineers. We do not staff project managers or account managers. You work directly with developers.
Our fixed price model means no surprises. We define the scope in the Roadmap phase and lock the price. If you add features, we adjust incrementally.
- Hires juniors and offshore teams
- Charges hourly with no guarantee
- Delivers in 6-9 months
- No compliance expertise
- Keeps code in their repo
- Adds scope creep without warning
- Only senior engineers (10+ years)
- Fixed price after Roadmap phase
- MVP in 8-12 weeks
- SOC 2, PCI-DSS, HIPAA built-in
- Source code in your repository from day one
- Scope changes discussed and priced upfront
Our Process for B2B SaaS Development
We follow a four-phase process to de-risk your project and ship fast.
Phase 1: Idea. You tell us your vision and target users. We audit technical feasibility and market fit in one week.
Phase 2: Roadmap. We produce a detailed spec, architecture diagram, and fixed price quote. This takes two weeks and costs $5K, which goes toward the build.
