17. Emma Hopkins, creative at Snap

Hopkins started out at Twitter as a presentation designer. When someone needed to get emojis designed she stepped in. That move would launch her career into the spotlight with her work being featured on ITV.

She previously worked with a number of brands including Cornetto, House of Vans, and Coleman's.

After two years at Twitter she joined Snap's growing team in London.
