SaaS software development.
Custom SaaS development - MVPs, multi-tenant platforms, vertical SaaS, and enterprise-ready features (SSO, SCIM, audit logs). From idea to paying customers in 10-14 weeks.
IRPR.io is a SaaS development company. We build B2B SaaS products for founders, scale-ups, and enterprise operators. Auth, billing, admin, email, analytics - the foundation every SaaS needs - are day-one deliverables, not phase 2.
We've shipped 50+ SaaS MVPs and scaled a handful from zero to $10M+ ARR. Our engineers know the difference between 'looks great in the demo' and 'holds up when 500 customers hit it on Monday morning.'
Book a call - we'll tell you honestly whether your SaaS idea needs 8 weeks or 8 months, and what enterprise readiness will cost when you need it.
Types of saas software we build.
Multi-tenant SaaS platform
Teams / orgs, role-based access, billing, and admin - standard SaaS foundation.
Vertical SaaS
Industry-specific SaaS (legal, healthcare, real estate, construction) with domain workflows.
B2B admin dashboard
Customer-facing dashboards with role-based views, exports, and audit logs.
Internal ops tool
Admin panels replacing spreadsheets for internal teams - multi-tenant-ready.
Workflow automation SaaS
Rules engines, triggers, and integrations (Zapier-style).

Who hires us for saas software.
What makes saas software hard.
Scope creep kills MVPs.
Most 'MVPs' drift into 9-month builds. We hold scope in the Roadmap phase so you actually ship in 10-14 weeks.
Enterprise readiness is expensive if bolted on.
SSO, SCIM, audit logs, SOC 2 - add them too late and it's a 6-month rewrite. We design for them at architecture phase.
Multi-tenancy bugs at scale are silent.
Data leaking between tenants is the worst B2B bug. We architect tenant boundaries from day one.
Churn is a product problem, not a marketing one.
Activation, retention, and expansion are built into the product. We ship analytics to prove it.
Your billing will become your bottleneck.
Most SaaS teams outgrow their billing setup in year 2. We build billing to grow with you.
The regulatory stack we ship against.
SOC 2 Type II
The audit enterprise customers will require before signing.
Controls designed from day one. Drata or Vanta for automated evidence. 6-8 months to a signed report.
SaaS MVPs that ship in 12 weeks.
Not a landing page. Not a prototype. A full, paying-customer-ready SaaS.
Founder MVPs are our most-shipped engagement because the pattern repeats: auth, billing, admin, email, analytics - then your specific value prop. We've built it 50+ times; it compounds.
Every MVP is production quality. No throwaway code. You scale it - we don't leave you a rebuild.
Typical MVP vs. irpr.io MVP.
The difference shows up when your 20th customer signs up.
- single-tenant by accident
- hardcoded JWT auth
- no audit hooks
- direct DB writes from UI
- enterprise = rewrite
- 6-month SaaS-ready sprint
- multi-tenant by design
- Clerk / WorkOS ready for SSO
- audit hooks on sensitive writes
- service layer abstracts DB
- enterprise = 4-8wk sprint
- ships paying-customer ready
How we build a SaaS MVP.
Four stages. Ruthless scope in every one.
What's in the 12-week MVP.
Wired on day one. Always.
- Multi-tenant auth (org / team / user)
- Stripe billing + webhooks
- Transactional email (Resend)
- Admin panel with impersonation
- Audit log on sensitive writes
- Product analytics (PostHog)
- Landing page + docs
- Terms / privacy / DPA templates
- CI / CD + staging
- Pen test before launch
