Formerly part of Mission Group, April Six specialises in working with clients in the technology and science sectors. The agency is located in London, Bournemouth, Munich, Singapore and the US.

US-headquartered Marketbridge has offices in the US, Canada and London, and offers integrated marketing and consulting services including marketing science and communications.

The acquisition bolsters Marketbridge’s global footprint and its ability to work with clients across a wider range of sectors.

The deal will result in 'comprehensive, data-driven strategies that optimise marketing spend', the companies said in a statement. 

John Shomaker, chief executive, Marketbridge, said: “This marks a significant step in our mission to eliminate fragmentation in sales and marketing efforts and provide our clients with integrated, high-velocity growth solutions. Together, we will continue to rewrite the rules of sales, marketing, and digital engagement to help global brands reinvent growth.”

Fiona Shepherd, founder and chief executive, April Six, said: “We’re excited to join Marketbridge and move to a model that brings business consultancy together with marketing execution, to make our client partnerships even more powerful. With so much shifting in the communications sector, we felt that now is the right time for a new journey for our business and, as part of the Marketbridge platform, we aim to help define the standards for the new dynamics between clients and agencies.”
