Sarah Wood is one of the co-founders of Unruly, a marketing technology company delivering social video campaigns.
Her work has seen her receive a slew of attention and awards: she was voted U.K. Female Entrepreneur of the Year, and features in Forbes' 2012 10 London-Based Entrepreneurs to Watch ranking.
And if that wasn't enough, she's also an associate lecturer at the University of Cambridge where she teaches an MPhil course in "Mash-Ups, Memes and LOLitics: Online Video Culture and the Screen Media Revolution".
Women's lack of confidence is the "glass ceiling in our culture and economy", Wood told CNBC at the Tech City Hall of Fame Awards ceremony.
"I think too many women count themselves out, they don't recognize their own strength," she added.
London, she added, is "the most significant, creative, productive technology hub in the world" because it absorbs new talent which brings in different cultures and ideas.
