About Eleven Hundred Agency
Eleven Hundred Agency was founded in London in 2018 by a specialist B2B tech PR pro – Claire Ayles – who had a long track record of scaling both boutique and global PR agencies. The agency was set up in response to a rapidly changing media landscape, where a growing number of tech companies were competing to get their brands in front of a rapidly shrinking pool of specialist journalists.
From the outset, Eleven Hundred set out to do things differently: focusing on strategic storytelling, targeted communications programmes and measurable business outcomes rather than volume-based PR activity. In other words, implementing PR campaigns designed to get brands noticed by the most influential journalists.
B2B tech PR is a highly competitive market, but the agency has consistently grown its revenues as well as its capabilities. It has won numerous awards along the way, recognising its business growth and differentiated approach, as well as the creative campaigns it has delivered for clients. It also has impressive client retention figures with more than 50 percent of its current clients partnering with the agency for five years or more. The average industry retention rate is approximately two years.
Employees stick around too, reflecting a culture to invest in and nurture its people. The average employee tenure is currently almost five years, almost double the industry average. This stability is key to developing meaningful and long-term client relationships.
As Kate Chappelle, CMO of long-term client NormCyber explains: “We have a true partnership with Eleven Hundred. They know our business inside and out, listen to us, help us solve problems and bring new ideas. They also achieve great results, which acts as a force-multiplier to all our efforts and supports our continued growth as a business.”
Today, the agency works across the full spectrum of the B2B tech sector: cybersecurity, SaaS, AI, critical infrastructure, martech, fintech, and more. Its team is adept at taking complex concepts and making them clear and relevant to UK business audiences, which means clients regularly appear in the business and industry media, as well as their core trade publications.
Clients are both start-ups and scale-ups, which need senior strategic counsel but often lack the extensive in-house communications resources enjoyed by their larger competitors. It is Eleven Hundred’s mission to make its clients – which also include SANS Institute, Fivetran, New Relic and Socomec – punch above their weight.
While AI is reshaping the media landscape, the Eleven Hundred approach remains unchanged: quality over quantity. The rise of AI has transformed both the stories clients want to tell and the way the agency secures coverage for them.
As business buyers increasingly use LLMs to research suppliers, trusted third-party sources are carrying more weight than corporate websites. That makes high-quality media coverage more valuable than ever, and it is precisely this kind of work that Eleven Hundred has delivered since day one.
