IRPR is a B2B SaaS website development agency. We build websites for SaaS companies using Next.js, React, TypeScript, and Tailwind CSS. Every site ships with a headless CMS like Sanity or Strapi for easy content updates.
A typical B2B SaaS website project takes 12-14 weeks and costs between $80K and $250K. We handle compliance needs like SOC 2, GDPR, and WCAG 2.1 AA accessibility. Source code is yours from day one.

Why B2B SaaS companies choose IRPR as their website development agency
We have built 200+ websites for SaaS companies across 50 countries.
Our team of senior engineers focuses on B2B SaaS website development. We use Next.js for static generation and server-side rendering, which improves SEO and load times. A typical SaaS marketing site we build scores 90+ on Lighthouse performance.
Every project starts with a Roadmap phase where we define the tech stack, page architecture, and integrations. We use Sanity or Strapi for headless CMS, Vercel for hosting, and Sentry for error tracking. Pricing is fixed after the Roadmap.
How IRPR is different from other B2B SaaS website agencies
Generic web agencies treat your SaaS website like a brochure. We treat it like a product.
Most agencies build websites on WordPress or Wix, then hand over FTP credentials. IRPR builds on Next.js with a headless CMS, stores code in your GitHub repo, and sets up a CI/CD pipeline on Vercel. You own everything from day one.
We also include performance monitoring with Sentry, uptime alerts with Datadog, and automated Lighthouse audits. Our fixed pricing model means no hourly billing surprises. A typical SaaS marketing site costs $80K to $250K.

Our process for B2B SaaS website development
We follow a 4-phase process that starts with a strategy call and ends with a live website.
Phase 1 is the Idea phase where we align on goals, target audience, and key pages. Phase 2 is the Roadmap where we define the tech stack, create a sitemap, and produce a fixed-price quote. This takes 1-2 weeks.
Phase 3 is the Product phase where we build the website in sprints. You see progress every 2 weeks. Phase 4 is the Release phase where we deploy to production, set up monitoring, and hand over documentation. Total timeline is 8-12 weeks.
What ships with every B2B SaaS website
Every project includes a set of deliverables that go beyond the website itself.
You get full ownership of the source code, a headless CMS, a CI/CD pipeline, and monitoring tools. No locked-in platforms or hidden fees. We also include a 30-day post-launch warranty for bug fixes.
Our standard delivery includes performance optimization (90+ Lighthouse score), SEO metadata for every page, and accessibility compliance (WCAG 2.1 AA). We also provide a deployment runbook and admin documentation.
