The Illumetis Waitlist · 2026

AI Meets Real Life Experience.

Illumetis is a private thinking partner for chief executives, senior leaders and boards. It is built for the moments where judgment and proven experience matters more than speed and generic musings.

It brings together advanced AI, deeply curated institutional knowledge, and decades of real-world executive leadership, governance, transformation and crisis experience to help you think more clearly, question more rigorously and decide more wisely.

Not generic answers. Not surface-level theoretical synthesis. A more credible, contextual and accountable way to work through complex decisions.

SUBTITLED
Manifesto

Three beliefs we build around.

01
Private means private.

Illumetis is a space for confidential thinking, not model training. Your questions, reflections and conversations remain yours alone.

02
Clarity beats volume.

More written text is not better advice. We value structure, judgment and the real context that sits behind the question.

03
Calm and considered beats urgency.

You need timely and considered support, not rushed thinking. Illumetis helps you move with pace, while protecting the quality and integrity of the decision.

Real-life experience,
brought into the room.

Three decades of transforming high-growth businesses — as a chief executive, board director, trusted advisor and consultant — have taught me one thing above method: effective transformation depends as much on the context and nuance of approach as on best-practice methodology.

I have led large, complex teams and organisations through major transformational change and growth, and today serve as a non-executive director and advisor across several. I thrive on the hardest organisational and behavioural problems — and on building environments where good governance, high-performing cultures and innovation thrive together.

At the heart of my work is a belief that impactful leadership begins with clarity of purpose: disciplined, proven frameworks to guide both tactics and leadership, focused measurement and accountability for results, and genuine alignment between people, technology and strategy.

I built Illumetis for leaders, executives and directors who recognise that growing their capability in the new AI era takes both confidence and ethical grounding — not blindly cutting and pasting AI outputs without context, but guiding and governing them with integrity and a firm footing in real-life experience.

Whether you are preparing for your first board appointment — or your tenth — testing and expanding your leadership, or seeking a 24/7 trusted advisor who understands the pressures of executive and governance life, my goal is to help you move forward with confidence, integrity and impact.

What Illumetis is

A contextualised advisor,
with memory and perspective.

Illumetis listens to your question, calibrates to your unique, specific professional situation and context, recalls the relevant real-life experience from Andrea’s knowledge base and insights, combined with relevant “Time Capsules” of past decisions by highly experienced leaders, and weaves in audio and written wisdom so you’re not starting from a blank page or a generic model response. It feels less like chatting with a tool, and more like stepping into an ongoing human conversation with a trusted advisor who knows your world and will help you frame and refine your options.

01 · PURPOSE

To give leaders structured, context-aware counsel at the moment of need, combining AI, curated knowledge and lived experience into a single, private workspace.

02 · WHO WE ARE

Created by Andrea Slingsby, a long-term executive and board governance practitioner, together with a small team of product designers and ML researchers focused on human-centred, governance-grade judgement AI.

03 · WHO IT IS FOR

Leaders who carry real accountability and responsibility: chief executives, chairs, non-executive directors and senior partners who want to think out loud in a safe, intelligent and professional environment.

Why now

You are making more important calls,
with less margin than ever for error.

47%

Of senior leaders say they “rarely” have time to test their thinking with a trusted advisor before a major decision.

24/7

How often your questions arrive, which is why Illumetis is designed to be there the moment they do.

Increase in leaders who say they “often rely on first-draft thinking” because the clock runs out.

Capabilities

Built for the way leaders actually decide.

SIX FEATURES · ZERO COMPROMISES
01 / 06

Confidential by explicit design

Illumetis is a private workspace, not an open data pipeline. Threads are encrypted, nothing you share is used to train future models, and your workspace stays within your own secure tenancy.

02 / 06

Grounded in real governance

Behind every response sits a curated body of proven decisions, audit work, crisis reviews and lessons learned, referenced for insight, not strip-mined for quotes, so the advice stays connected to real-world consequences.

03 / 06

Editorial answers, not blurts

Responses arrive in a clear, simplified and structured format compared to traditional LLMs: what’s at stake, how the issue is framed, the viable options, the second-order effects, and what you can do next, so you can move from “noise” to “usable” in a single read.

04 / 06

Always-on counsel

Illumetis is there when the real work happens: at 6am before the call, at 11pm after the board meeting ends, in airports and hotel rooms and between meetings when the traditional business advisor is not online or available. Carrying your context forward so each conversation builds on the last.

05 / 06

Time Capsule replays

You can mark a decision, capture the reasoning in the moment, and return to it weeks or quarters later to see what you knew, what you assumed and what actually played out.

06 / 06

Scenario patterns that feel familiar

Stress-test a path against patterns that look like your reality: your sector, your scale, your geography, so you’re not just asking “has this ever happened?” but “what tends to happen when it looks like this?”

From early users

What leaders are saying, quietly.

№ 01
"It’s the first time I’ve used an AI product that feels like working with a real professional advisor, not a generic chatbot. It remembers the context, asks better questions than I do, challenges me to actually think about the relevance of the options I have to choose from, and helps me walk away clearer and calmer."

"We ran Illumetis alongside a traditional LLM during a tight M&A window. The difference was stark: the generic tool summarised documents; Illumetis challenged our assumptions and highlighted the one risk scenario no one around the table had named yet."
James M.

"The experience feels less like “typing into a box” and more like thinking out loud with a senior partner. The structure, the Time Capsules, the way it brings past conversations back into the thread — it has really changed how I prepare for board and management conversations."
Adaeze O.
Managing Partner · Private Capital
№ 04
"What surprised me most was how it slowed me down at exactly the right moments. It seems counterintuitive — I usually want speed — but it showed me that what I really need is to slow down and think more deeply. Instead of chasing answers, it helped me reframe the question, replay prior decisions and see patterns I’d been too busy to notice."

"I’ve tried most of the usual LLM tools; they’re fine for drafts and emails. Illumetis is different. It feels purpose-built for leadership and governance decisions. The UX nudged me towards better thinking rather than just faster output."

Questions

Reasonable
things to ask.

Who is Illumetis for?

Illumetis is for chief executives, executive and aspiring leaders, board directors, and managing partners who are already responsible for outcomes. The system is designed for people for whom the cost of a wrong call is measured in quarters or careers, not weeks. It is deliberately not designed for individual contributors who are just seeking generalised "fast" answers.

How is this different from a general-purpose AI assistant?

Illumetis isn’t a general-purpose AI; it’s a focused decision partner built for leaders. Instead of being trained on the open internet, it’s grounded in executive and board-level decisions, lived experience, governance standards and your own organisational context. Illumetis delivers structured, defensible answers rather than long chatty responses — with a real company standing behind the quality and accountability of its advice.

What happens to my data?

Conversations are encrypted end-to-end and tenanted to your organisation. We do not use your data for model training, in any aggregated or anonymised form. Independent audit reports are available on request.

Is there a free tier?

No. Illumetis is offered to a small number of cohorts each quarter. Pricing is shared once an invitation is accepted, and is structured per executive seat.

When will I get access?

Invitations are sent in cohorts of roughly fifty. Most members of the current list are reached within six to ten weeks of joining.
