How We Took FinanceFlow from 0 to 50,000 Users in 90 Days

When FinanceFlow approached us, they had a compelling product idea and six months of runway. Our challenge: build a multi-tenant SaaS platform that handles enterprise compliance while remaining delightful to use.

Architecture Decision

We chose Next.js for the frontend with a Node.js microservices backend on AWS. PostgreSQL provided relational integrity for compliance, while Redis handled sessions and real-time data.

Result

50,000 users in the first 90 days. £2M in monthly transactions processed. 99.99% uptime since launch.
