Hilder is co-founder and Chief International Officer of Crowdpac, the platform for new politics, where he once worked with Steve Hilton.

[6] In the same piece, Hilder reported on Douglas Carswell's successful 2014 by-election campaign after switching from the Conservatives to UKIP and on the Scottish referendum campaign, and on the subject of "new politics" through conversations with figures such as Jon Cruddas, Rory Stewart, Lisa Nandy, Stewart Wood and Maurice Glasman.

Hilder argued that "over the coming months and years, this new politics will shake the British establishment to its foundations.

It has many faces but a common origin: the growing consensus that the status quo is broken and old politics is actively disempowering".
