Stuckonhomework.com has chosen Braben to handle its UK comms and website launch.
The site will provide homework help for GCSE students in England, Wales and Northern Ireland through more than 200 short video lessons featuring a teacher.
Braben will drive awareness of the site and raise stuckonhomework.com’s profile among business and consumer audiences.
Outgoing Tesco chief executive Sir Terry Leahy, retiring from the retail giant this month, has personally invested in the new venture.
Stuckonhomework.com was formed by Helen Royle and Teresa Watts, ex-senior executives at the BBC and ITV.
Royle originally came up with the idea when she was unable to help her teenage children with their homework, and saw a need for a site that offers video-based GCSE support specifically designed with pupils in mind.
Matt Bourn, managing director, Braben, said: 'Stuckonhomework.com is an exciting new digital business using video-on-demand and social media in a dynamic way to shake up the education sector.
'There is a real need in the market for a site that delivers quality, curriculum-based support designed for GCSE students, taking into account their online behaviour and habits.'
