New York does not run its own version of Somerce. It runs the same one: the same reporting, the same weekly trading rhythm, the same host roster and studio output that produce the numbers everywhere else. What sits in New York is judgement close to the market — specialists who know US retail calendars, US creator behaviour and US shopper habits, making trading calls in hours that overlap with the brands they run.
The LIVE studios stay in London and Manchester, because that is where the broadcast infrastructure and the trained host roster already exist. New York's job is the strategy either side of the broadcast: catalogue and offer decisions, affiliate targeting and the account relationship, wired straight into the machine that already manages £100m+ GMV across 80+ brands.
