The Practice

Three mandates. One standard: full operational handover.

Advisory to decide well. Interim leadership to execute. Training to make the capability permanent. Every mandate ends the same way: with the system working and the team running it.

Mandate 01

Strategic Advisory & Consulting

For leadership teams validating complex decisions: data strategy, AI governance, CRM architecture, and international go-to-market. Leaves a workable plan and internal capability, not ongoing consultant dependency.

2025

Mandate 03

Executive Training & Masterclasses

For leadership teams that need shared judgment, not another vendor deck. Custom programs for organizations whose leadership needs to make decisions about AI, not just use the tools.

The through-line is real: the multi-agent systems of my postdoctoral research connect directly to the multi-LLM orchestration I design and teach today.

How Engagements Run

Architect. Embed. Hand over.

The same three phases govern every mandate. They scale to what you need: a plan, a leader, or a trained team.

01

Architect

Diagnose the current system, validate the target architecture and strategy, and define the outcomes the engagement will be judged on.

02

Embed

Build alongside the team. Hire or transition permanent leadership, and install the documentation, rituals, and decision rights that make the system durable.

03

Hand over

A structured, dated handover: documentation, training, shadowing. Leadership in place, nothing dependent on me.
