Bombay Bicycle Club's Jamie MacColl is leading a campaign to get young voices heard when Brexit negotiations begin.
The guitarist says he started Undivided to give under-30s the chance to have their say in the process of Britain leaving the European Union.
The aim is to bring together people who voted Leave and Remain in June's referendum.
"I think this is the most important political time of our generation, and maybe the century," he tells Newsbeat.
"Whether you like it or not, politics fundamentally affects our lives.
"And you're more than entitled to remove yourself from the process, but don't be upset when decisions are made that hurt you."
Jamie says they're attempting to get the views of around a million young people by January
The 10 best ideas will then be chosen by the group and presented to MPs in the new year, ahead of the start of Brexit negotiations.
"I think the initial aim of the campaign was to bring people that had voted both ways together in the name Undivided," says Jamie.
"The referendum has caused a lot of division in this country and we might as well start by trying to heal those.
"But young people as an interest group have become increasingly unrepresented in politics and this is an effort to try to remedy that."
Jamie says the EU referendum has made more under-30s aware of the power of politics.
He says he hopes more will be done in the future to get people engaged with important issues from a younger age.
"Trying to get young people to vote even five years or in a referendum, when they're not taught about politics the rest of the time, is a bad starting point.
"It needs to start in schools."
As well as being able to have your say on the Undivided website, events will be held at schools, universities and workshops around the country over the next few months.
