Chris Sacca, Lowercase Capital founder and Twitter investor, said on Thursday that once the question of CEO is cleared up, there will be "immediate turnover" on the Twitter board of directors.
"One of the things that we've seen from Jack Dorsey over at Square is he is great at building a talented board full of smart, successful and challenging members who can keep the company moving at its best," Sacca told CNBC's "Squawk Alley."
"We don't have that at Twitter right now, and I think we're going to see that for sure."
Shares of Twitter were down more than 6 percent on Thursday as investors awaited the announcement of the company's next permanent CEO. Sacca said he is "highly confident" that interim CEO and Twitter founder Dorsey will get the permanent seat.
"This isn't a hypothetical situation, he's been back in charge of Twitter now for over a quarter and over that time we've seen the product road map accelerate dramatically," he said.
