Straight answers
Extra Medium is a marketing agency in London, and social is where the city talks back. We plan and run social, content and creator campaigns that earn attention in the boroughs you serve, and through our lab we run Magpie, a platform that books local creators, so influencer marketing is something we operate, not just recommend.
Social in London is a hundred scenes sharing a postcode map: Soho creative, City finance on LinkedIn, the food queues of Borough Market, football culture that swallows weekends whole, and a TikTok city that finds a new neighborhood hero every week. Content built for a generic Londoner reaches none of them. We build for the specific audience in the specific place, with a voice that sounds like a person from there rather than a brand performing local. The test is simple: would someone who lives there share it, or scroll past it politely?
Most agencies recommend influencer marketing from the outside. We operate it. Magpie, built in our lab, is a platform where local businesses book local creators for comped experiences or paid posts, and it shows each creator’s local reach before anyone books — because a million followers worldwide are worth less to a London business than ten thousand neighbors. That operating experience shapes every creator campaign we run for clients: local reach over follower counts, terms agreed in writing, and content the creator’s audience will actually believe.
Attention is the start, not the deliverable. Organic social builds the audience, paid social puts the best of it in front of the people who have not found you yet, and the reporting ties both to enquiries, bookings and sales. Our full approach sits on the services page. A feed full of likes and an empty till is a hobby, and an expensive one. We would rather post less, mean it more, and show you the money line at the end of the month.
Key takeaways
The ones your customers are on, which is a research question, not a fashion answer. For many London companies that is Instagram and TikTok for consumers, LinkedIn for business buyers, and one or two more at most. Being everywhere thinly is worse than being somewhere properly.
We do: strategy, creative, production and posting, with creators brought in where a local voice carries further than a brand account can. You approve direction and see everything before it runs. What we will not do is hand you a calendar of filler and call it a strategy.
