Why B2B SaaS Companies Choose a Senior Development Company
A senior B2B SaaS website development company ships faster, hits compliance standards, and keeps your codebase clean.
IRPR has delivered 200+ SaaS websites across 50 countries. Every engineer has 8+ years of experience. We skip the discovery theater and start building in week 1. Our 8-12 week timeline beats the industry average of 6 months by a significant margin.
We write code that passes SOC 2 Type II audits, HIPAA BAAs, and PCI SAQ A assessments. Every site ships with Sentry error monitoring, Vercel analytics, and automated Lighthouse scoring. No tech debt, no unfinished features.
Generic Dev Shop vs. IRPR as Your Senior B2B SaaS Website Development Company
The difference between a generic web agency and a team that understands SaaS metrics, pricing pages, and conversion optimization.
Most web developers build brochure sites. They don't understand how a pricing page impacts trial-to-paid conversions or how a blog workflow connects to your CRM. They hand off bloated WordPress themes that slow down over time.
IRPR builds every B2B SaaS website on Next.js with server-side rendering for SEO, incremental static regeneration for fast load times, and headless CMS for marketing team autonomy. We ship with automated CI/CD and 99.9% uptime.
- Builds with WordPress or Wix with no headless option
- No conversion rate optimization (CRO) on pricing pages
- Delivers 5-7 months late with scope creep
- No SOC 2 or HIPAA compliance support
- Hands off bloated code that costs $2K+/month to host
- No integration with Stripe, HubSpot, or Segment
- Builds with Next.js, TypeScript, and headless CMS (Strapi, Contentful)
