The founding cohort · 19 November 2026
Ninety-nine boards. One room. It convenes once.
A board-level transformation event for the C-suite of enterprises with 500 to 2,500 employees — live on Zoom at 13:00 UTC, followed by a single in-person meeting at a top-tier hotel.
Companies in total, plus Mathias Koester as host. Hard capped.
Thursday. The founding cohort convenes at 13:00 UTC.
Employee band. Enterprises outside it are not eligible.
Executive board only. Human resources managers are excluded.
Start time — Thursday 19 November 2026, 13:00 UTC. 05:00 Los Angeles · 08:00 New York · 13:00 London · 14:00 Berlin · 15:00 Johannesburg · 18:30 Delhi · 21:00 Bali. The session is recorded; every seat receives the recording, so a director in a difficult time zone loses nothing by watching later.
01 — Allocation
When the ninety-nine are gone, the cohort closes.
The cap is not a marketing device. Beyond ninety-nine the room stops being a room and the delivery model — personal, direct, unmediated — breaks. There is one cohort and one only: when the ninety-nine are taken the programme closes to new clients and does not reopen.
The attention then belongs entirely to the ninety-nine. Each engagement runs on a twelve-month term that renews automatically into the next unless notice is given under the engagement contract, with the quarterly tariff continuing — so the relationship is a long one by design rather than a course that ends.
Renewal is also the door to the annual executive summit — the room where the ninety-nine convene each year to network as a cohort. Participation is exclusive to clients whose engagement is unbroken: a client that leaves and is later re-admitted pays an additional £30,000 per quarter on re-entry.
The arithmetic of one empty chair makes the term worth protecting. A single director out for a quarter — burnout, a cardiac event — costs an enterprise millions before the loss is even measured. Prevent one such absence and the year’s tariff has already paid for itself.
One seat is one enterprise, not one person — the seat is held by the company and the attending directors are named to the office on reservation. Seat allocation is updated by the office as reservations are confirmed. A seat is held for seven days from enquiry, then released.
Who is in the room
- Chief executives. The person accountable for the number the programme moves.
- Chief financial officers. Presenteeism, absence and replacement cost are their line items.
- Chief operating officers. Where unplanned absence turns into missed schedule.
- Board directors. Including non-executives with a remuneration or risk remit.
- Top sales agents. By arrangement, where an introduction is being made.
Who is not
Human resources managers are excluded by design. They are rarely party to a decision at this level, and the register of the room changes when the conversation shifts from financial exposure to benefits administration. HR becomes central at deployment — not at the case.
02 — Format
Three hours. Three movements. One roadmap.
The session is delivered personally by Mathias Koester and is structured to finish with a decision rather than a follow-up. For the C-level board it is live on Zoom, followed by the in-person meeting at a top-tier hotel.
-
Movement one · Diagnostic
What this is costing you today
Your organisation’s financial exposure, itemised: health insurance premiums, presenteeism, absenteeism and replacement cost, modelled against your own headcount and salary structure rather than a sector average.
-
Movement two · Strategy
The evidence-based protocols that stop it
The published interventions with the strongest measured effect on the drivers identified in the diagnostic — biochemical, metabolic and cognitive — and what each is documented to return.
-
Movement three · Implementation
The ninety-day deployment roadmap
Sequencing, named owners inside your business, and the measurement framework your own team will run internally. The board leaves with a plan, not a proposal.
-
Included · Company-wide · Pre-recorded
The annual employee session
Every employee in the organisation receives a dedicated online session once a year as part of the tariff, delivered as a pre-recorded broadcast so the same message reaches the whole workforce without a live connection to fail. It covers the facts of the deficiencies draining the business and what each person should do about them, and it is where the company-wide presenteeism and medical saving is actually realised.
-
Included · C-level · Every six months
The biological optimisation test
Free of charge for the C-level board and covered by the tariff. It sets the executive baseline, and it is repeated every six months so the movement in the markers is measured twice a year.
The shape of the day
Live, in person, and on record.
Three movements, in order. The working session is live; the recording follows to every seat, so no time zone loses anything.
- 13:00 UTC · Live on Zoom
The founding cohort convenes
The C-level board session, delivered live by Mathias Koester to the ninety-nine. The whole C-level board of every company joins — five to six executives per board.
- Following the session · In person
One board meeting at a top-tier hotel
Three named directors from each company — ordinarily the chief executive, chief financial officer and chief operating officer — at a top-tier venue confirmed to reserved boards. Three per company keeps it a boardroom rather than a conference: the people who sign, own the numbers and run the operation.
- After the meetings · On record
The recording reaches every seat
The session is recorded and the recording goes to every reserved seat. Separately, every employee in each organisation receives the annual pre-recorded broadcast through one circulated link.
The venue
A top-tier hotel, confirmed on reservation.
The in-person board meeting is held at a top-tier venue. The location is confirmed to reserved boards by the office — the room is sized to the cohort, and the cohort is capped.
