@will_brown + @WalterGR sorry that it was unclear. This was one ad-campaign targeting just Thomas (+ 6 randomers). I ran a number of other variations targeting investors that were connected to him and others in his network. These still didn't target too many people (I'd say <100); but still got a lot of attention.

I'm also guessing that some people might have just told him they'd seen his face on a LinkedIn ad. Not necessarily clicked through to it.
