In June 2012, Mensch joined forces with former Labour digital adviser Luke Bozier to set up a social networking website – a politics-based rival to Twitter. The site, named Menshn – pronounced "mention" – allowed users to select their topic of interest. Mensch hoped to raise venture capital finance. The site was initially criticised by IT industry experts for using "http" instead of secure "https" to communicate passwords. Bozier disputed this claim, but the site switched to the secure protocol. Menshn closed in February 2013.
