Corporate transformation, finance, security, legal, and procurement tend to cluster around headquarters, while product, editorial, studio, ad-sales, agency, client, or engineering buying centers may sit in separate hubs.
Field events and ABM should follow the buyer: New York and London are common media and advertising centers; West Coast offices matter for gaming, creator, streaming, and engineering teams; regional offices matter for sales and client delivery.
