The problem

§ 01

Meridian's founders were selling regulatory horizon-scanning to mid-size financial firms using a process held together by spreadsheets, a shared inbox and heroic effort. Every new client added linear headcount cost, and two enterprise prospects had walked away after seeing the 'platform' behind the demo.

They had a clear wedge and real demand. What they didn't have was software — or eighteen months of runway to build it the traditional way.

The build

§ 02

We ran a one-week discovery to cut the surface area ruthlessly: one regulated workflow, one user role done exceptionally well, everything else deferred. The fixed quote and scope came out of that week.

The build was a multi-tenant Next.js application on Postgres with row-level security, a rules engine for regulatory deadlines, and an audit log designed to survive a due-diligence review. Auth, billing and SSO came from proven primitives rather than custom code.

Meridian's team saw a staging deploy at the end of every week from week two. Their feedback in week five — that reviewers lived in email — became a digest feature that closed their first enterprise deal before we'd even launched.

They cut scope harder than we dared to, and it's the reason we shipped. The platform closed our biggest deal while it was still half-built.
