House 337 was formed in September 2022, from the merger between creative agency Engine Creative and fashion and lifestyle specialist, ODD Group. The vision for the new business was as a collective offering its 337 founding employees greater control over their working lives. It was inspired by new working practices post-pandemic.

Now parent, Next 15, is merging House 337 with Elvis, part of a major rationalisation of its agencies, from 22 to 12. The two agencies will maintain their individual brands and serve clients as before for the time being.

The merged agency will be led by House CEO, Phil Fearnley. Elvis CEO, Tanya Whitehouse, is leaving after seventeen years with the agency, eight as CEO.

Fearnley stated, “Tanya has been a remarkable leader. Not just for Elvis, but for the wider group. She’s built a business known for its creativity, integrity and heart, and leaves behind an incredible legacy. There’s now an exciting opportunity to bring those ingredients together with the world-class creative, AI and technology expertise of House 337, and harness those strengths more fully in service of our clients.”

House 337’s client roster includes the Royal Navy, Santander, Women’s Aid, and Sweaty Betty and in December 2023, it acquired AI voice assistant consultancy, Vixen Labs.

Digital and creative agency, Elvis, was founded in 2003 and acquired by Next 15 in 2017. Its clients include Cadbury, Sony PlayStation, Honda, and Cycling UK and since 2022 it has had a strategic partnership with sister agency, Planning-Inc entered a strategic partnership with sister agency Planning-Inc for CRM.
