How do you build and maintain the best marketing teams?

We are navigating an era of unparalleled uncertainty, economic flux and rapid technological evolution.

In marketing, the core theoretical pillars of the discipline – research, strategy, tactics – remain unchanged. And yet all can now be enhanced by AI. Meanwhile media channels – from TV to Social Media are in seeming melt-down and the ‘new normal’ vs ‘what is possible’ is redefined each day.

Amidst this chaos, a skilled big business marketer needs to to create agile talented teams who effortlessly blend a ‘can-do,’ ‘tech-savvy,’ multi-stream approach with real-world experience and the human touch. Ideally, they’ve been schooled ‘Mark Ritson’ style , care deeply about all of the touch-points of your brand and have creative fire in their bellies.

And then you need to lead them to deliver against the business goals.

Enter our guest curator for this session: Advisory Board member Maria Koutsoudakis, (Chief Brand Officer for VodafoneThree, UK). Across business and consumer, Maria and her team oversee’s Vodafone brand presence from data and insights, across all media channels, sports sponsorship and events.

But beyond her stellar marketing work, Maria’s direct report team at VodafoneThree is one of the longest serving:

“For me, it’s not how people have behaved in the past, but how they behave when you give them an opportunity, as part of a team: when they get given trust and the opportunity to innovate, to be passionate about what they do and to be creative. I’ve seen people in my teams be given those chances and seen them really flourish.”

Join us for a fire-side chat with Maria, a panel discussion with our experts Craig van Neikerk (Global VP Marketing Malibu & Kahlúa), Charlotte Snelgrove (Head of Marketing, Octopus Energy), David Brewerton (Growth Marketing Director, Monzo Bank)… and more to be confirmed. We’ll have round-table discussions and time for networking, with a light breakfast and refreshments in a central London venue.

Our briefings are trusted, no-sales, peer-driven community events where senior-level marketing directors unite to exchange real-world insights, confront challenges, and drive leadership forward. You’ll leave inspired, ready to implement new ideas and having made new and meaningful connections with industry experts.

Terms and Conditions

Seniority screening

Little Grey Cells is a ‘brain trust’. We are unashamedly elite (in the sense of ‘invite only’, for the most senior marketers in the UK) – but not elitist (in the sense of not stuffy, snobby or formal). Our attendees are exclusively of the same level of decision-making marketing responsibility as our advisory board. As a result we screen all registrations to ensure that marketers who attend our events meet this criteria. Thanks for your understanding.
