Catherine Buttery, founder of an online publishing company called Constellation Digital, Tweeted: "Totally agree [with Parra]. I've come across similar situations with early stage investors. Including questions regarding relationship status."
Parra has so far raised £250,000 for her app, which she plans to expand to four US cities later this year.
She said VC attitudes are unlikely to change until a technical female cofounder successfully IPOs or exits a company like Facebook or Twitter, adding that it shouldn't be too long before this happens.
Twitter, which is hold its first UK mobile developer conference in London today, said it is keen to promote and support women who want to break into the technology sectory.
Techworld contacted the British Venture Capital Association for comment but it is yet to respond.
