None of the UK's private companies valued at more than $1 billion supported leaving the EU, The Guardian report in May.
The 14 unicorns, of which five explicitly said they would be supporting remain, were concerned that leaving the Union would affect trade and business.
TechUK, a trade body representing more than 900 UK companies in the technology sector, has responded to the vote saying that it "opens up many uncertainties about the future".
The group said it had starting to plan how it should respond to policy and regulatory changes that will be caused by leaving the EU.

Following the referendum result, Dame Julia Goodfellow, the president of Universities UK – a collection 133 universities – said the body would look to "secure opportunities" for students and researchers to be able to access "vital pan-European programmes".
