I've written so many stories about John Clifton Davies, the serial con man who continues to slick-talk tech companies into thinking he's a billionaire investor. In reality, his scam is simple: Find companies that are desperate for investment, dangle $20-$100M investments, and then insist the whole thing is managed by a third-party "due diligence" firm that is actually run by them and is a complete scam. They just go around bilking companies out of tens of thousands of dollars in due diligence fees, and then disappear and rebrand.
Over the past month I've heard from a bunch of his new victims, some of which have already sent his firms money. Incredibly, these scammers are still re-using the same boilerplate text in their bullshit investment sites that they used in past scam sites. It's a reliable "watermark" for them that they never bother changing, no matter how many times I point it out in a story.
Not sure I can be bothered to write about this guy yet again, but for the record his current scam due diligence firms are ROI Capital (roicap.co) and Apertura (apertura.uk).
