Global
Consulting
Summit.
One week a year, senior partners from across the world's consulting firms convene online — five days, closed doors, Chatham House Rule — to take a measured, cross-firm read of the year ahead.
No single practice
sees the whole
picture anymore.
The questions reaching senior partners now cut across sectors, geographies and disciplines. GCS is the one week a year peers from financial services, public sector, health, energy, defence, industrials and tech meet in one online room to compare notes under Chatham House Rule. Closed door. Peer only. Consultants only.
Five days. One closed room.
No mainstage. No livestream. No clients in the room. The week is built around the conversations partners rarely get to have together.
Peer only
Senior partners, principals and chief economists from the firms that shape the global advisory market. No clients, no press, no sponsors in the room.
Chatham House
Everything said is on the record for thinking — never for attribution. The point is to say what you actually believe, not what's been cleared by comms.
One synthesised Outlook
The week has one quiet deliverable: a cross-firm read of 2026, drafted by the council from the room's discussion. No firm logos on the cover. No individual positions to defend.
The questions our clients
are bringing to the table.
The week,
at a glance.
Nine rooms. One room, nine angles.
Sector breakouts run in parallel through the week — financial services sits next to defence, health next to energy, public sector next to tech. Small enough to actually argue. Move between them freely — every attendee gets the opening, the breakouts, and the sign-off.
Each room is capped — typically 8 to 12 voices, one speaking partner chairing, one rapporteur taking the read into the Outlook.
Fifty voices.
One synthesised read.
Plus regional firms, government advisory practices and sector boutiques — by invitation of the council.
An FS partner and a public-sector partner sit with the same weight. So does energy, health, defence and tech. No headline track, no second-class room.
Speaking partners frame the chapters of the 2026 GCS Outlook. Synthesised by the council. No firm logos. No individual quotes without your sign-off.
Your sector counterparts from every other major firm — and the partners advising on the other side of your sector. An exchange that doesn't happen at any retreat or offsite.
Take a sector breakout. Steer the discussion. Your frame becomes the one the Outlook reflects.
Every session you contribute to becomes a citable artefact in the GCS Insight Library — searchable and referenced for twelve months.
Fifty speaking partners. No sponsor tiers, no upsells, no expo, no media. The room stays small on purpose.
"Five days in the same room as the partners we usually only meet across a pitch table. That alone is the value."
— Founding council member
Two ways into the room.
Both for consultants only.
Fifty speaking partners are invited by the council and chair the rooms. Everyone else attends to listen, ask, and take the read back to their practice. Every application is verified against a consulting-firm email — the room stays consultants-only.
