The closest thing I've had to that is my side project Taaalk (https://taaalk.co) - it's a platform for online interviews.
After the success of one of our interviews on HN [1], someone contacted me and suggest that I interview a highly successful value investor. We had a great 'Taaalk' [2] and he then put me in touch with an investing friend of his in London who runs a fund. We met for lunch and he taught me all about how he invests in shares, it was very straight forward, so I started following his guidance and made 50% on my money last year [nothing magical, just solid and practical value investing advice] - meaning I could take the year off and do a masters in Psychology of Mental Health - which is (slowly) helping change my career into a direction I love.
I wouldn't listen to the advice of anyone that thought they could make 50% return in a year just based on "nothing magical, just solid and practical value investing advice".
They're either too naive to realise it was luck, or trying to scam you.

P.S. Anyone can make their own interview, so if you have a friend you think should be interviewed - please keep Taaalk in mind :)
