The challenge
Northline had strong early demand and a clickable prototype, but no product that could take real customers — no tenant isolation, no billing and no way to onboard teams without a call.

Case study · SaaS · B2B platform

Northline had strong early demand and a clickable prototype, but no product that could take real customers — no tenant isolation, no billing and no way to onboard teams without a call.
A multi-tenant platform with SSO-ready auth, team roles, audit logs and Stripe billing with trials and usage limits, plus product analytics and self-serve onboarding. Two-week releases with a demo every Friday.
Paying users arrived in week seven. Within a year the platform served more than 3,000 teams, passed its first enterprise security reviews and shipped four times as often as before.
“They took our SaaS from a Figma file to thousands of paying teams. Senior engineers, weekly demos and zero drama.”
