Carrie Longton and Justine Roberts

Justine Roberts and Carrie Longton co-founded the parenting discussion website Mumsnet in 1999. Today the site is the first port of call for many new mothers and fathers, receiving over 8 million visits a month. It generates revenue through advertising and giving companies access to users who review their products.

The website has a prominent role in national political debate and leading politicians take part in regular webchats. The sites ability to draw the party leaders to answer members questions led to the 2010 General Election being named the ‘mumsnet election’. The site has also run high profile campaigns on a range of issues including the sexualisation of childhood - ‘Let Girls Be Girls’ and to improve services for those who have an early miscarriage.
