Bloomberg reporter checked Wikipedia where it clearly says, "In 2014, Altman was named president of Y Combinator, which he had been a part of as a founder..."[1].
Of course, if the reporter had spent a few more seconds reading the entire sentence he may have gotten it right: "In 2014, Altman was named president of Y Combinator, which he had been a part of as a founder in the first batch of funded companies in 2005."
