Robyn Denholm has had a very busy day. There was an appearance at Sunrise, the start-up conference run by Blackbird, the venture capital firm where she is a director. And there was the Wall Street Journal, which reported that the board of Tesla, where she is chairwoman, had given serious thoughts to ousting the electric carmaker’s chief executive, Elon Musk.

Does Denholm want to talk about Musk? No, she does not. But while the mercurial businessman is off the agenda, Tesla isn’t. This is the first interview Denholm has given since it was reported that the board sounded out executive search firms and considered replacing Musk.
