Top 13 Adtech Companies in London Ranked


Category: Uncategorized

Adtechadvertising technology—is all about the tools, analytics, and software that companies use to track and inform digital advertising and consumer behaviour. It’s become vital for running effective ad campaigns, capturing consumer attention, and maximising ad spend. By better understanding behaviour and patterns, companies can advertise to the right audience at the right time, and win more business.

Ad technology companies in the UK have capitalised on increasing web traffic and the growing demand for more personalised advertising over the last few years. Since 2011, the United Kingdom’s 440 high-growth adtech startups have raised £1.45b in equity funding, much of which—£1.18b to be exact—has been secured by companies based in London. 

As the time we spend online continues to increase, and businesses across the world desperately try to increase revenues to pre-COVID-19 levels, the adtech industry could have a very lucrative future. In this article, we’ve ranked the top 13 London adtech companies, according to the total amount of funds raised.
