Use case

Commercial due diligence

Underwrite the commercial story before you commit a partner to the deal. Market attractiveness, competitive position, standalone viability and the price at which the return actually clears.

The questions it answers

Is the market growing, and is that growth durable or cyclical?

Where does the target really sit against named competitors?

Does the standalone cost base hold once it leaves its parent?

At what entry price does the base case clear your hurdle?

Which risks are underwritable, and which are deal breakers?

Example structure

An example of how a commercial due diligence is structured

  1. Market exposure and growth scenarios
  2. Standalone challenger viability and execution risks
  3. Standalone carve-out viability
  4. Deal viability and valuation sensitivity
  5. Acquisition gate criteria and KPI framework
Questions we get

Before you commission one

How is this different from asking a general AI tool?

A general model answers immediately and never tells you what it does not know. Every Lumiu claim is footnoted to a named source on the same page, and every section ends with the conditions that would make the recommendation wrong.

Who signs off the work?

On the platform, the reasoning system produces the report and no human puts their name to it. On a consultant-owned project a senior ex-MBB or ex-Big Four consultant owns the engagement end to end and signs every section.

What if we disagree with the conclusion?

The report tells you how to argue with it. Each section states what would change the call, so you can test the recommendation against your own view rather than take it on trust.

Can we use it on a live deal?

Yes. Work is confidential as standard and mutual NDAs are signed on request. Enterprise clients can run Lumiu on a private instance or on their own premises.

Platform

Expert network

Confidential subject-matter experts, brought into an engagement when the question needs one.

Human in the loop

Three to five expert interviews on every consultant-owned project

Operators, scientists, regulators and former executives, brought in per engagement when a question needs a specialist rather than a generalist.

Included, not extra

Three to five interviews are part of a consultant-owned project.

Screened for conflicts

Experts are checked against your target and your portfolio.

Attributed by role

Findings appear in the report by role and sector, never by name.

Beyond the network

Additional specialists can be sourced per engagement at cost.

How it runs

  1. You state the question the experts need to settle
  2. We source specialists from a confidential network, screened for conflicts
  3. Interviews are run by the consultant who owns your project
  4. Findings are written into the report, attributed by role rather than by name
Use case

Feasibility study

A structured answer to whether the thing can be done at all, before anyone spends money finding out the hard way.

The questions it answers

Is the opportunity real once the assumptions are stated?

What capability, capital and time does it require?

Which constraints are regulatory, and which are self-imposed?

What is the minimum viable version worth testing?

What would make this a clear no?

Company

Security and confidentiality

How Lumiu handles your documents, your deal and your data.

How we handle your work

Your deal does not leave your control

Never used for training

Your prompts, documents and reports never train a model.

Confidential by default

Work is confidential as standard. Mutual NDAs signed on request.

European company, GDPR

Lumiere AI is French, operating under GDPR, with DPA available.

Private deployment

Run Lumiu on a private instance or on your own premises.

Questions buyers ask us

Is our material used to train models?

No. Prompts, uploaded documents and finished reports are never used to train models, ours or anyone else's.

Where is the work processed?

Lumiere AI is a French company operating under GDPR. Data processing terms are available on request, and we will sign a mutual NDA before an engagement begins.

Can we run it inside our own environment?

Yes. Enterprise clients can run Lumiu on a private instance or on their own premises, with their own seats and access control, supported by our forward-deployed engineers.

Who can see a consultant-owned project?

Only the senior consultant assigned to it and, where you approve them, the subject-matter experts interviewed for that engagement.

The firm

The people behind Lumiu

Built by people who lived both sides of the table, consultant and client, with the engineering depth to make a reasoning system that holds up under real stakes.

Commercial due diligence, growth strategy and value creation for private equity, sovereign wealth and governments across Europe and the Gulf, at Strategy& and PwC. He ran the work on the ground from Dubai and Paris, on live transactions and on national-level strategic initiatives.

Before consulting, a sniper team leader in an airborne parachute regiment of the French Foreign Legion, decorated more than once. That mix shaped how Lumiu is built: rigorous problem structuring, stated assumptions, and recommendations that survive contact with real constraints.

Why we built Lumiu

Some decisions keep you up at night

The ones where you are the person everyone is waiting on, where being wrong costs real money and real jobs, and where, if you are honest with yourself, you are not sure you have enough to go on.

The help you can reach for has never quite fit. Bring in a firm like McKinsey and you wait months and pay a fortune, often for work done by people barely out of university, and by the time the deck lands the moment to act has half passed. Turn to a general AI tool and in seconds you get something polished that you read with a knot in your stomach, because it never asks what it does not know, it never tells you when you are wrong, and nobody answers for it.

Lumiu starts with what you are actually trying to decide, digs into the reality around it, takes a position on what moves the answer, and pressure-tests that position until it holds. You get a direction, the reasoning underneath it and an honest read of the risks. Our ex-MBB and ex-Big Four consultants review the work and put their name to it whenever you want that weight behind you.

This is not something a competitor can assemble quickly. Anyone can buy the same models and build an interface on top. What takes years is the consulting logic itself, thousands of reasoning steps and over a thousand proprietary frameworks drawn from how strategy is genuinely done, with real consultants standing behind the answer.

Use case

Value creation

Margin and cost programmes that survive contact with the operating business. Where the savings are, what they cost to capture, and what you must protect.

The questions it answers

Which cost pools hold the largest realistic savings?

What is capturable this year against structurally fixed?

What gets damaged if you cut too deep, and where?

How should the programme be sequenced?

What proves it is working in the first two quarters?

Example structure

An example of how a value-creation plan is structured

  1. Margin-recovery levers: pricing, inventory, channel
  2. Cost-reduction opportunities by cost pool
  3. Cost programme and protected reinvestment framework
  4. Feasibility and sequencing of the programme
  5. Do and do-not framework, with peer benchmarking
Questions we get

Before you commission one

How is this different from asking a general AI tool?

A general model answers immediately and never tells you what it does not know. Every Lumiu claim is footnoted to a named source on the same page, and every section ends with the conditions that would make the recommendation wrong.

Who signs off the work?

On the platform, the reasoning system produces the report and no human puts their name to it. On a consultant-owned project a senior ex-MBB or ex-Big Four consultant owns the engagement end to end and signs every section.

What if we disagree with the conclusion?

The report tells you how to argue with it. Each section states what would change the call, so you can test the recommendation against your own view rather than take it on trust.

Can we use it on a live deal?

Yes. Work is confidential as standard and mutual NDAs are signed on request. Enterprise clients can run Lumiu on a private instance or on their own premises.

Lumiu, by Lumière AI

The AI-native strategy firm

Commercial due diligence, market entry, growth strategy and value creation. Decision-making reports where every figure is cited to a named source. Built in hours, signed off by senior ex-MBB and ex-Big Four consultants. In days, from 15k to 30k euros, when human judgment, revision and sign-off are needed.

Try it yourself for 100 euros, with no human input. The introductory rate will cease soon and move to 1,500 euros per report.

Who we work with

Advisory for high-stakes decision making

Private equityScreen more targets than your team can cover, before you commit a partner.
Venture capitalSize a market and pressure-test a thesis inside your decision window.
CorporatesAnswer the board's question without a three-month engagement.
Private creditUnderwrite the commercial story behind the paper you are pricing.
FoundersThe analysis a board expects, without a procurement cycle.
How it works

AI agents plus top-tier human consultants

Each section lands the way a partner would ask for it: at a glance, why it holds, what would change it, and the sources that carry it.

01

Scope

You state the decision. Lumiu challenges the framing and fixes the question before any work starts.

02

Research and analyse

Filings, ratings reports and market data, cross-checked, then modelled. Sizing, valuation, IRR and MOIC, cost pools.

03

Challenge

A red-team pass attacks the conclusion before you see it, and the result is written into the report.

04

Human sign-off

On a consultant-owned project a senior ex-MBB or ex-Big Four consultant owns and signs every section.

05

Expert interviews

Three to five confidential subject-matter interviews, included on consultant-owned projects.

06

Deliver

A board-ready report and deck, presented in your boardroom.

Strategy in the age of AI. Sourced, defensible, accurate, at a fraction of the cost

Bring in a big firm and you wait months and pay a fortune, often for work done by people barely out of university. Use a generic AI tool and you get something polished in seconds that never asks what it does not know, never tells you when you are wrong, and answers to nobody. Lumiu is the third option.

The rigour of a top firm. The speed of a machine. A price that makes sense

By consultants, for decision makers

The playbook was written by people who did the job at Strategy& and PwC, on both sides of the table.

Human judgment, machine scale

Hundreds of agents do the work. A senior consultant owns the call and puts their name to it.

Fully traceable

Every claim footnoted to a named source on the same page, never buried in an appendix.

A fraction of the cost

A comparable engagement at a traditional firm runs 150k to 300k euros and takes four to six weeks.

The work

Should an investor commit to Harvey at 15.5bn dollars?

Commercial due diligence, prepared for an investment committee. Public sources only: no data room, no management access, no customer references.
