We already have a product but we are working on mobile app version
Hard to provide specific/relevant suggestions without knowing anything about your product or whether you're aiming for personal, corporate or product notoriety. Try throwing a cream pie at the Prime Minister or robbing a bank!
Ok Thank you Henry for this helpful answer :)
Our product is a new communication tool (mail - chat -cloud on the same screen) ethic (confidential and green) and we are laughing the mobile app!
I was laughing at my first response, so it's only fair you should be "laughing the mobile app"!
On the assumption you meant 'launching' instead - and seek notoriety - it should be fairly easy: if it's a confidential communication app, you could issue a press release saying it's been developed as the perfect tool for criminals and terrorists!
A slightly less notorious approach might be to laud the work of famous whistleblowers such as Edward Snowden or Julian Assange - or, indeed, my own little handiwork in exposing the MPs' expenses scandal a few years ago here in Britain.
Hope that helps and good luck with the launch!
