🛡 Sphere Custodian programme

Every country-level sphere is run by one verified SME — an expert who knows the area through experience. The custodian seeds and expands the sphere and its sub-spheres, approves new cards, bulk-uploads data and keeps the taxonomy clean. Pilot custodian, UK – Rail Network: the founder. When a new national sphere is requested (e.g. UK Buses), a custodian is appointed for it.

🪪 Who owns a card?

  • The card belongs to the company, not the person. A named employee keeps it updated; if they change job the card stays with the company and the new employee is assigned as editor.
  • Responsibility for accuracy sits jointly with the company and its named employee.
  • Sphere data can be uploaded in bulk by the custodian, but each card is maintained by its owner.
  • Employees can browse linked spheres as a live map of companies — and career moves — in their field; sales teams get a direct line to new business, and buyers to suppliers.

Market intelligence

GREAT BRITAIN
See where the market is crowded — and where it isn't. Every supply area below is scored by how many companies compete in it, so you can spot saturated categories to negotiate hard on, and single-source exposure where one supplier failing would stop work.
COMPETITION BY SUPPLY AREA
Counts reflect companies currently mapped in this sphere. As the atlas fills, thin areas will thicken — a low count can mean a genuinely concentrated market or a gap in coverage, so treat single-source flags as a prompt to check, not a conclusion.
