Alex Pearmain

Alex was one of the early UK pioneers of brand social media adoption. He has built awarded social media, service, communications, and digital marketing teams for consultancies, agencies and within major brands. His work at O2, as the first head of Social Media demonstrated that it was possible and desirable for major organisations to utilise social media at scale across customer services, sales, retention, brand and communications activity, blazing a trail for other brands to invest and adopt. He brings together analytical data and creative strategies.


Katie Buckett

Katie is a digital brand communications expert, with experience working both in and for global and UK organisations. She began her career within Vauxhall’s marketing communications team, and has subsequently worked as a digital brand communications consultant across sectors as diverse as consumer technology and professional services. She has co-ordinated global multi-market programmes around digital creative, influencer identification, social activation, and community management.

I’ve known Alex and Katie for years (in fact we met when I was Alex’s client at Just Eat) so I knew it wouldn’t be so bad, and even if it was, I could…

17.10.18 / Social media is good

There we said it.

It’s a dirty concept.

Verboten, ‘other’, naive.
