I’m running a project, with Real Business and Everline, to identify the UK’s 50 most disruptive, early-stage businesses. We’ve now hit 50 nominations, so it’s time for an update on some of those putting themselves forward:

A major innovation in loyalty cards, focusing on the independent retail sector. Collaborative consumption comes to the pre-owned designer fashion market. Mobile car tyre replacement = bye bye KwikFit. Recruitment disrupter features strongly with one business turning the traditional model of recruitment on its head; and another providing a unique online marketplace to match high-quality interns with corporate employers. The pre-hospital A&E sector is also ripe for disruption, says one nominee. Another is aiming to bring technology to police whistleblower calls. And, three cheers, the estate agency model is being challenged by a well-backed start-up.

Deadline: January 6. Find out more here.
