Bonderman said in a statement sent to Reuters that he did not want his comments to create distraction for Uber, which is working to rid its culture of sexual harassment and discrimination.
His resignation from the board is effective Wednesday morning.
During Tuesday's meeting, Uber board member Arianna Huffington spoke to employees about the importance of adding more women to the board of directors.
"There's a lot of data that shows when there's one woman on the board, it's much more likely that there will be a second woman on the board," Huffington said.
In response, Bonderman said: "Actually, what it shows is that it's much more likely to be more talking."
The comment was disclosed through a recording of the meeting that was published by Yahoo. An Uber spokesman verified the authenticity and accuracy of the recording.
Bonderman, who is a founder of private equity firm TPG Capital, an Uber investor, shortly after wrote an email to Uber staff to apologize.
"I take full responsibility for that," he said. "I need to hold myself to the same standards that we're asking Uber to adopt."
Bonderman and other board members had joined Tuesday's staff meeting to lay out recommendations from an investigation into sexual harassment, diversity, inclusion and other employee concerns led by former U.S. Attorney General Eric Holder.
Holder's law firm was retained by Uber in February after former Uber engineer Susan Fowler wrote a public account of her time at the company, which she said was marred by sexual harassment and an ineffective response by management.
The recommendations, which were unanimously adopted by the board on Sunday, call for reducing Chief Executive Travis Kalanick's sweeping authority at the firm and instituting more controls over spending, human resources and the behavior of managers.
