Co-founder Brown Leaves Chairman's Role at mediasense

Independent media and creative advisory firm mediasense has announced that its co-founder Graham Brown is to step down from his role as Executive Chairman to become a Non-Executive Director. He leaves leadership of the company in the hands of CEO Jamie Posnanski.

Founded by Brown and Andy Pearch in 2009, mediasense (it appears to have dropped its capital letters during 2025) operates a media auditing platform called DiPA (Digital Performance Analytics), powered by a proprietary insight engine, machine learning techniques and a team of analysts and data scientists. The firm, which has been majority-owned since 2021 by private equity firm Apiary Capital, bought PwC's Marketing & Media advisory team last year, and a year ago added creative and media advisory specialist R3.

Brown, who will continue to contribute to mediasense's long-term strategy, says the transition is 'a natural step for [him] at this stage', but says he will remain 'deeply committed to actively participating at the Board and supporting the executive team.' He comments: 'The team has led the successful integrations of two acquisitions... and the company now has a fully integrated offering, with an end-to-end suite of capabilities that will serve the needs of marketers.'

Posnanski, who replaced Brown as CEO in December last year, states: 'Graham's commitment to the business - and our industry as a whole - has been integral to the foundation of what mediasense is today. I look forward to our continued work together in his role as a trusted advisor and strategic voice on the Board, while our executive leadership team drive the company through its next phase of growth.'
