Mark Sullivan Panellist
Director of Partnerships and Growth · gther

Mark Sullivan is Growth & Partnerships Director at gther and an event industry commentator with a career spanning conferences, experiential events, brand activations and event technology. Having worked across both the creative and technology sides of the industry, Mark brings a practical perspective on how technology can enhance live experiences, and where it can sometimes get in the way.

His experience ranges from conferences and communities to major brand experiences, giving him an understanding of the different pressures facing organisers, agencies, brands and technology partners.

Today, Mark works closely with event professionals to explore how technology, data and emerging tools can solve real event challenges and create better connections between people. A regular attendee and commentator at industry events, he is particularly interested in the intersection between technology and human experience, and believes the best event tech should enable engagement rather than become the experience itself.

Having spent much of her career agency-side, including leading global marketing at experiential agency 2Heads, Sara has worked with brands, event teams and technology partners across conferences, exhibitions and major international brand experiences. Today at gther, she brings that experience into the event technology space, helping shape how technology responds to the real needs of organisers, agencies and audiences. Alongside her industry career, Sara is an award-recognised fiction writer, giving her a particular interest in stories, what we learn from them, and how sharing the less-than-perfect ones can help us get better.
