I've been doing this tech nonsense at moderately high levels for over 45 years now, and over the years I've had business dealings with members of these "30 under 30" lists, and every single fucking time it's a conman, a grifter. I don't even bother with heavily marketed individuals nor their flagships anymore. They are nonsense.
It reminds me of one of two people (at the same time and place in my life) I was introduced to because they shared national origin (i.e. nationality at birth, or parents nationality) with me.
One later got into the Sunday Times rich list (the under 40 section, IIRC) during the dot com bubble, by the simple expedient of lying. He claimed to be working on encryption software that was hugely valuable and said it was valued in billions. He actually owned a smallish local computer shop. He later fled the country claiming MI5 were persecuting him for developing such good encryption software.
TO be fair, he seems to have fooled financial institutions too. He bought a Ferarri (presumably on credit) and Amex gave him a black card (which he tastefully put a picture of on the company website). It did not take a lot to see through the fraud, the actual business was decribed on the website.
The other person I got introduced to around the same time for the same reason turned out to be a member of a terrorist organisation. Not banned here at the time, but still not someone I particularly wanted to meet.
