Why choose a dedicated b2b saas website development firm
A generic marketing agency does not understand your technical buyer.
Your audience is CTOs and product managers who judge your site on speed, security, and clarity. IRPR has built 200+ B2B SaaS sites, each optimized for conversion rates of 4% or higher.
We use Next.js with server-side rendering for fast load times and SEO rankings. Every site passes Lighthouse scores above 90 and ships with Sentry error tracking and Hotjar session recording.
Generic web shop vs. a b2b saas website development firm
Most agencies build brochure sites. We build conversion machines.
A generic developer will give you a WordPress theme and a plugin stack. You will get slow load times, weak security, and no clear way to iterate based on user behavior.
IRPR builds with a modern JAMstack: Next.js on Vercel, content via Sanity, and analytics through Amplitude. Your team can deploy changes in minutes, not days.
- Built on WordPress with page builders
- No CI/CD pipeline
- Average Lighthouse score below 70
- No A/B testing infrastructure
- Code not documented or owned by you
- Hourly billing with scope creep
- Next.js or Remix with Tailwind CSS
- CI/CD on GitHub Actions with preview deployments
- Lighthouse score 90+ guaranteed
- Integrated Google Optimize or VWO
- Full source code ownership
- Fixed price, no surprise invoices
How we build your b2b saas website in 8-12 weeks
Our process is transparent, fast, and outcome-driven.
We start with a 2-week Roadmap phase where we audit your existing site, analyze competitors, and create a detailed scope document with wireframes and tech decisions.
Then we build in 2-week sprints. You see a live preview after the first sprint. Stakeholder reviews happen every two weeks, and we ship the final site in week 10-12.
