Senior B2B SaaS Development ConsultantsDevelopment Consultants
We build B2B SaaS products for enterprise buyers. 200+ products shipped in 12 weeks or less.
IRPR is a team of senior B2B SaaS development consultants who build production-grade products for enterprise and mid-market buyers. We use React, Node.js, PostgreSQL, AWS, and Stripe to ship scalable SaaS platforms that handle complex billing, multi-tenant architecture, and compliance from day one.
Every engagement starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. Typical MVP timelines are 8-12 weeks with budgets from $80K to $250K. We build for SOC 2, HIPAA, PCI-DSS, and FERPA compliance as needed.
Our clients are B2B SaaS founders who need a technical co-founder replacement, CTOs at Series A companies who need to ship a new product line, enterprise innovation teams launching internal SaaS tools, and PE firms building portfolio company platforms.

Why hire senior B2B SaaS development consultants
Building a B2B SaaS product is different from consumer apps - it demands multi-tenant architecture, enterprise security, and complex billing.
Generic web developers often miss critical SaaS requirements: tenant isolation, SSO integration, usage-based billing, and SOC 2 compliance. IRPR's senior B2B SaaS development consultants have shipped over 200 products across 50 countries, each with these features built from the start.
We use a fixed-price model based on a 2-week Roadmap phase. No hourly billing, no scope creep. Your MVP ships in 8-12 weeks with source code ownership, CI/CD pipeline, and Sentry monitoring included.
Generic dev shop vs senior B2B SaaS development consultants
Most agencies build websites. IRPR builds production SaaS platforms that handle enterprise billing, compliance, and scale.
Hiring a generalist web development agency for your B2B SaaS product often leads to technical debt, missed compliance requirements, and a product that can't scale past 100 users. Senior B2B SaaS development consultants at IRPR bring deep experience in multi-tenant architecture, SOC 2 readiness, and subscription billing.
We have shipped SaaS products for fintech, healthcare, logistics, and education clients. Every project includes a 2-week Roadmap phase where we define the architecture, tech stack, and fixed price before writing a single line of production code.

How senior B2B SaaS development consultants deliver your product

IRPR's senior B2B SaaS development consultants follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline. You know exactly what you get and when.
The Roadmap phase (week 2) produces a detailed specification with wireframes, data model, API contracts, and a fixed price. No surprises. The Product phase (weeks 3-10) builds your MVP in 2-week sprints with demos every Friday.
