Unless you've been in a coma, you will obviously know of Uber, the minicab ehailing smartphone app that has disrupted taxi markets in more than 300 cities worldwide, including London.
But you may be less aware of the substantial impact its explosive growth has had on UK companies.
For instance, Eco City Vehicles (ECV), the former supplier of the six-seater Mercedes Vito to taxi companies, partly blamed weak trading in the first half of 2014 on "uncertainty caused in the licensed taxi trade by the emergence of Uber."
The chart below shows the precipitous decline in Eco City's share price over the past three years. The group entered and then exited administration during this period and now operates as a technology, media and telecoms investment company....sound familiar?
The easy availability of private cash could delay an Uber flotation:
Uber boss Travis Kalanick recently said the group is "nowhere near" the point of seeking a public listing. "Give us a few years," he added.
Uber entered the London market in 2012 to much furore - it recently won a legal battle over the right to operate in the capital. Its UK operations posted a tenfold increase in turnover to £11.3m, according to the subsidiary's latest Companies House filing.
Reports have been publish which allege that although the company turned over £11.3m, it paid less tax in the UK than 5 average London Taxi drivers have in total.
