Why your B2B SaaS needs a senior development partner
Building a B2B SaaS website is not a simple brochure site. It has compliance, authentication, and performance requirements.
IRPR has shipped over 200 SaaS websites for companies in 50+ countries. Our average timeline is 10 weeks from kickoff to deployment. We use Next.js for server-side rendering and static generation, ensuring fast load times and SEO performance.
Every website we build includes automated testing with Cypress, Lighthouse scores above 90, and SOC 2 compliant deployments. We also handle SSO integrations with Okta and Auth0 out of the box.
How IRPR differs from generic web agencies
Most agencies hand your project to juniors or offshore teams. IRPR assigns senior engineers only.
We have a fixed-price model determined in the Roadmap phase (week 2). You know the cost before we write a line of code. No hourly billing, no scope creep charges.
Your project has a dedicated senior engineer who communicates directly with your team. We use async-first workflows with daily overlap hours for US and EU time zones.
- Junior developers handle your code
- Hourly billing with unpredictable costs
- No compliance expertise (SOC 2/HIPAA)
- Standard templates, not custom UX
- No CI/CD pipeline delivered
- Code ownership not guaranteed
- Senior engineers only (8+ years experience)
- Fixed price from $80K - $250K
- Built-in SOC 2, HIPAA, PCI-DSS compliance
- Custom design system with Tailwind CSS
- GitHub Actions CI/CD + Sentry monitoring
- Full source code ownership
Our process: from idea to launch in 8-12 weeks
We follow a 4-phase process that de-risks the build and ensures on-time delivery.
Phase 1 is the Idea phase where we align on goals and scope. Phase 2 is the Roadmap where we produce a detailed project plan with fixed price. Phase 3 is Product where we build in 2-week sprints. Phase 4 is Release where we deploy and monitor.
During the Roadmap phase, we define exact features, integrations, and compliance requirements. You get a document that serves as your blueprint. No assumptions.
