Fire on the Hill and Fourth Day to merge to expand international strategic communications offer

F ire on the Hill, and Fourth Day, along with its sister company Quatrième Jour, are merging to create an international strategic communications agency with wholly owned offices in London, New York, Paris and Manchester.

The combined agency, which will operate as Fire on the Hill, will bring together Fire on the Hill’s strengths in international communications, strategic advisory and purpose-led storytelling with Fourth Day’s expertise in media relations, strategic content and multi-market campaign delivery.

The merger gives clients access to a broader senior team, deeper strategic and digital expertise and stronger international delivery. The agency will support organisations across sectors including technology, energy, manufacturing, investment and education, from high-growth startups to established global brands.

The combined business will manage an international partner network across APAC, EMEA and LATAM, enabling clients to access on-the-ground expertise across key global markets.

An international platform for growth

Chris Clarke, co-founder and managing partner, Fire on the Hill said: “Clients are facing a more complex communications environment, shaped by geopolitical uncertainty, AI disruption and declining trust. They need partners who can give senior advice, protect reputation and deliver campaigns across markets. Bringing our two agencies together gives us the scale, expertise and agility to do that.”

“Fire on the Hill and Fourth Day share the same ambition: to build an international agency with the reach clients need, alongside the senior attention and entrepreneurial energy they value”, added Sarah Mulder, co-founder and managing partner, Fire on the Hill. “Our merger gives us the opportunity to grow further by bringing together the characteristics that have made both agencies distinctive.”
