A network of doctors offering online, paid-for consultations via a webcam, Push Doctor treats conditions such as sore throats, joint pain and asthma, providing online prescriptions via email or post.

It charges £14 for a 10-minute appointment, with prescriptions at £4.50 and fit notes at £12.50.

Founded in the UK in 2013 by Eren Ozagir, formerly MusicMagpie’s CMO, and Matt Elcock who ran Gap’s IT in Europe, it has raised more than $9m (£6m) in two rounds of funding.

It aims to get patients seen by a doctor within three minutes, has a network of 7,000 GPs and is tapping into people’s desire for on-demand services.

It can share medical consultation details with a patient’s registered GP, if they give permission, and is working with the NHS to develop Push NHS.
