Three advisors.
Three domains.

Composition

Why these three.

We didn’t want a symbolic advisory board. We wanted access to people who had already navigated the regulatory, technical, and operational challenges that LumeSec will face.

01

Banking IT, end-to-end.

From data-centre operations to executive IT leadership inside regulated banks. Every architecture decision is filtered through someone who has run the stack.

02

Risk, where it counts.

Twenty-five years of credit risk, governance, and back-office board work — the disciplines that decide what a regulator will accept.

03

Integration, under audit.

A decade at the integrators that wire enterprise IT together, plus court-certified expertise — the view from where systems actually meet each other.
