“And that was a response to the hedge fund thing.”

Marc Andreessen, a16z co-founder, interviewed 1 January 2018 The Tim Ferriss Show Transcripts: Marc Andreessen (#163) (Tim Ferriss blog)

Andreessen said that "that", which in context seems to mean his firm's deep involvement in health, was "a response to the hedge fund thing". He added that very smart founders had been telling the firm it was "dumb"; the passage does not say what "the hedge fund thing" was.

Own records only Only the person's or their organisation's own records speak to it, so it is not scored.

Said for an organisation they lead or work for; it counts on both records.

Reasoning
