The Problem

A fintech startup had a validated product spec and six months of runway — but no engineering team and no time to hire one.

What We Built

We assembled a six-person dedicated team within two weeks, took ownership of architecture and delivery, and shipped the full platform to production in five months.

The Impact

2,000+ users onboarded in the first 90 days post-launch. Series A raised. Engineering team still on retainer.
