"Seahorse has been much more than a public relations & communications firm, they have been a strategic part of our communications and government relations strategy, leaning in, being proactive, and driving thought leadership…..They are our communications & strategic partner, fully integrated into our business."

Bob Psaradellis, former CEO, Renewable Power Capital
"Seahorse brings a high level of professionalism and political intelligence to all of their work. They planned and delivered a parliamentary event with a minimal steer that was instrumental to the successful launch of LCEF. Their knowledge of the political landscape and attention to detail ensured a smooth and stress-free operation at an extremely busy time."

Paul McNamee, Founder of Labour Climate and Environment Forum
"Seahorse has been an integral part of the River Action project since its inception. From helping recruit a world-class advisory board, making a significant input into the communications strategies around our various campaigns – to then engaging with our key stakeholder groups across the media, political and NGO landscapes– Seahorse's connectivity has been a huge asset….It would be fair to say that without their connections and capabilities it is difficult to see how we could have launched River Action at the time we did and made the impact we have."

Charles Watson, River Action Founder and Chairman
"Seahorse combines expert environmental knowledge and a fantastic network with insightful media and political analysis, offering clients unique and personalised strategic advice."

John Burton, CEO World Wise Foods and Member of On The Hook
"Seahorse has been invaluable in supporting Greenpeace's political campaigning on the Fisheries Bill. They've been passionate about the brief, quick to spot new opportunities, and tireless in all they've done."

Rebecca Newsom, Head of Politics, Greenpeace
"Seahorse has been an invaluable part of the Zero Carbon team from the outset, and their support has been integral to the progression of the campaign. They have worked tirelessly to secure high-level engagement with policy development across Government, business and civil society stakeholders, and are constantly going above and beyond to generate new leads and create opportunities for the campaign. Their passion, expansive network and range of expertise is a true asset, and we are delighted to have been able to partner with them."

Hannah Dillon, Head of the Zero Carbon Campaign
