One hour. One day. One quarter.
We build the part of your organisation nobody wrote down. Start with an hour. Commit to a day. Build for a quarter.
We demonstrate for free. We intervene for a fee. Every engagement starts with a 45-minute call.
One hour
You, then your team · two calls
A private one to one first, on the problem that keeps coming back. Then a short session with your team, dropped into a regular meeting, showing what is currently possible at the frontier.
You leave with:
- Your missing middle, seen for the first time
- Your team’s first real look at frontier AI, not Copilot
- A shared appetite for the 1-Day, built on trust, not a pitch
An hour is enough to know what you have been missing.
One day
Your leadership team · one value stream
Rebuild one real piece of management work, live, with frontier AI: the board paper, the investment decision, the steering meeting.
You leave with:
- Workflows redesigned, first MVPs, a backlog of use cases
- The start of your business case
- A team that has felt what AI does to its own judgment, and knows what building this will take
A day is enough to change what your team believes.
One quarter
Your team · a three-day Residency
A three-day Residency, wrapped in three months of embedding.
You leave with:
- Your backlog built, the unwritten written down
- A learning loop that compounds: what you build keeps working long after we leave
- A living Org Mirror: AI shows your organisation as a political system, an ecosystem, a system in flux (and others), so you see why problems keep recurring and where to intervene
A quarter is enough to lay the first bricks of the missing middle.
Zone 02 / The hour · Free
It starts with a 45-minute chemistry call, to scope the problem that keeps coming back.
Then we sit with you, alone. An hour on your own leadership work, live with frontier AI. You see where you really stand before your team does.
Then we come to your team. One regular meeting, an hour, working your problem with the best of what is currently possible. Prepared prompts your team runs themselves, room for every question, and a first taste of what is coming.
You’ll know by the end of the second visit whether the 1-Day is for you.
Zone 03 / The 1-Day Experience · Four figures
One piece of management work. Your team. Rebuilt with frontier AI, in a day.
Your work, deconstructed by your team, then rebuilt with AI.
A leadership team, an intact unit, or a hand-picked crew of eight to fourteen.
The most senior accountable leader is in the room, whichever it is.
Real pieces of management work with named owners.
The board paper, the investment decision, the steering meeting, the handover that always slips.
We put the work on the table and rebuild it live with frontier AI.
You feel the speed, the friction and the judgment calls as they happen. By the end the whole system is visible to everyone and one piece of it is already rebuilt.
The day only works on good preparation, and we run it with you in the two weeks before.
A short anonymous survey so we open on where the room really stands, pre-reads and short videos, a compact session to get everyone’s access working and a first hand on the tools, a voluntary one to one for anyone who wants to ask in private, and the use cases chosen, owned and timed. We work on the stack you already own, and bring frontier tools into the room alongside it, so you judge the difference yourself.
Zone 04 / Why a day, and why you
You can’t imagine what you’ve never experienced.
The more senior you are, the further you sit from the tools, and the less you know what you are asking your organisation to do. The day moves AI from your unknown unknowns to known knowns.
You can delegate expertise. You can’t delegate understanding.
The direction of travel is published. AI-native firms run 25% smaller, with 15% fewer managers, at comparable valuations.* COOs now say in public that the leadership team, rather than the technology, is the primary constraint on the transformation it claims to lead.** Edgar Schein showed that leaders shape culture through what they repeatedly pay attention to, measure and control. A day of your team’s attention on its own work, with AI in the room, is the safest place to close that gap.
What leaders pay attention to is what the organisation becomes.
Zone 05 / How the day is designed
Knowledge just got cheap. Knowing didn’t.
Knowing is built the way any craft is: in the hands, through repetitions on real work. That is why the day is designed around doing, and why we build it on four kinds of knowing.
PropositionalKnowing that
Facts, frameworks, claims. Reports, slides, analyses. This is where most corporate time goes, and every AI tool automates it. Its scarcity is disappearing, which means everything you will be paid for from here sits in the other three.
AI replaces this
ProceduralKnowing how
Skills built through repetition. How to brief AI, how to iterate, how to decompose a complex challenge into delegable tasks. Built through practice on your real work.
Built in the room
PerspectivalKnowing what matters
Judgment. Seeing what AI got wrong. Knowing when an artefact will land with a stakeholder and when it will be rejected. The most valuable, and the hardest to develop.
The judgment work
ParticipatoryKnowing through co-creation
Trust through co-creation. Identity reshaped by what you build with whom. It only happens face to face, under real pressure, and it decides whether anything lasts past the day.
The human layer
In the morning, I stood in front of a spaceship and hit my leg very hard. I didn’t even manage to open the door. Now I feel I actually opened the door to the spaceship. I feel AI enabled.Participant · regulated European energy client
Zone 06 / What you leave with
What you leave with.
The strategy work gets done in the room, by the people who must own it.
Workflows redesigned, first MVPs, a backlog of use cases.
Chosen by your team, on your work, in the day.
The business case to go beyond Copilot.
You see the same workflow with your current stack and with frontier tools. The delta is your argument to take upstairs.
A team that can judge AI.
They have felt what it does to their own thinking. They can tell where it earns its place, where it erodes the decision, and which calls stay human.
A direction.
A first shared sense of how management will change here, built on evidence your own team produced, and a pathway into the quarter if you want to walk it.
The model is the same for everyone. What your team does with it is the difference. Here’s what one team did:
We did not start with the technology, we started by identifying the three workflows that actually mattered to us. The Challenger House team had my team working on them within days. The proof is what happened after, the team is still at it every day, and I can now clear a backlog I simply could not have cleared before.Dr. Christof Kortz · VP Scouting & Programmes, E.ON Group Innovation
The 1-Day · One day · Your team of 8 to 14 · Four figures
Zone 07 / The Build · Five figures
One quarter. Your missing middle, built inside the work.
Three months wrapped around a three-day Residency, on the workflows you actually run, with your real data and real stakes. The 1-Day ends with a backlog. The Build starts from it.
Before · weeks 1 to 4Define
We turn your backlog into defined use cases and map the stakeholders. We work 1:1 with every participant at the Drawing Board, where people say what they would never say in front of peers and boss. We take the baseline: your Talking Tax, where the hours go, how long the work really takes. Everything that changes over the quarter is measured against week one.
The core · three daysThe Residency
Three days with your intact team, off the treadmill, on the workflows you named in the 1-Day. You bring the real problem and the real data. We bring frontier AI into the room and rebuild those workflows with you until your team can run them without us. A month of work in three days, and the speed turns out to be the smallest part of it.
After · weeks 5 to 12Embed
New ways of working draw attention. Budgets get questioned, credit gets contested, and the people it unsettles look for reasons to slow it down. We stay through it, inside the quarter: office hours, masterclasses, ambassador roles, weekly rhythms, measurement against your baseline, and a sparring partner beside your sponsor for the conversations that decide whether good first results survive. If the sponsor is the most senior person, they survive.
Imagine someone promises to serve you the most amazing dessert you ever ate, and this guy is just describing it to you. The ah moment comes when you taste it. Being here creates the moment when you taste the dessert in real life.Participant · regulated European energy client
Zone 08 / What you leave with
What you leave with.
After three months, your team can take a real workflow, rebuild it with AI inside it, and keep going without us. They can tell where AI earns its place and where it erodes the decision, and they know which calls stay human.
The artefacts:
Your missing middle, built and running. Named owners for quality, decision rights for where the machine and the expert disagree, and a place where what the team learns is kept.
Three priority workflows, chosen by your team, rebuilt and running with AI inside them.
A living Org Mirror. AI reads your organisation as a political system, an ecosystem, a system in flux, so you see why problems recur and where to intervene. Early, built client by client.
The Writing-Down Protocol. Guided interviews, AI-assisted drafting, expert review: ten years of know-how written down in days instead of lost in a handover.
Instruments built for your meetings. One example: a 73-point positioning model became an asynchronous vote that replaced ten hours of debate with one hour of individual judgment.
Board-ready evidence from the room. Working demos, cases, maps, multimedia. Zero slide decks.
From previous Builds: handover packages from months to days, with the receiving side pressure-testing them in the room. A clickable KPI dashboard the team built itself. Three to five times reported speed on research, drafts and mockups, and a backlog cleared that had been immovable for months. And after the Residency, the group set up ambassador roles in their home teams and a weekly sync of their own, unprompted. That is what adoption taking root looks like, and it is rare.
The Build · Three months · Your intact team · Five figures
Zone 09 / Next
Five figures. Three months, your intact team, the most senior accountable leader as sponsor. It starts with the call.
Book a call →Zone 10 / Why residential
The AI transition happens either way. Challenger House is where you design it.
This is where strategy, executive education and leadership team development stop being separate calendar items. Alignment on what AI may decide, what stays human, and who is rewarded for writing things down gets decided by a leadership team in one room, together. AI compresses the screen work, so the team work finally gets the time it needs, including the 10pm conversation that changes the project’s direction.
Zone 11 / What we are experimenting with
Two experiments we run with pioneering clients, in full conviction that this is where lasting advantage gets built. Both are load-bearing structures of the missing middle.
The Org Mirror. AI reads your organisation through the lenses of organisational theory: as a political system, a culture, a system in flux, and others. An MRI, not a surgery. You see why the same problems keep coming back and where to intervene. The ambition is a living mirror your organisation runs on itself, and we are building it one client at a time.
We believe every organisation will run a living digital twin of itself. The early ones will see what their rivals can’t.
The AI Constitution. Your why, written down, with skin in the game. The CEO writes the manifesto, the leadership team authors the constitution, IT and Legal build the guardrails. It answers the question most AI principles skip: if writing down your tacit knowledge is what makes AI work, who gets rewarded for it? We facilitate. You hold the pen.
We believe an organisation without one doesn’t have an AI strategy; it has tools and governance theatre.
