About me

I run a boutique influencer marketing and social media agency, One Roof Social. Launched in early 2016, after seeing a gap in the market for a pragmatic approach to including influencer activity into a media or marketing plan. Having worked brand side (heading up launch marketing, PR and social media for Vestiaire Collective) I struggled to find an agency that understood what a brand needed to be able to assign spend to influencer marketing. Influencer marketing is its own beast, and can’t be fused into a PR approach or performance marketing channel. It requires its own approach and performance metrics. At One Roof we aim to help “de-muddy the waters” for our clients who include Ralph Lauren, Hobbycraft, John Lewis & Partners, KPMG, Elizabeth Arden and Save The Children. We run campaigns and consult; working from the inside to help make social media and influencer marketing commercially worthwhile.
