Dave McClure has resigned as general partner at 500 Startups, he confirmed Monday in a tweet.

"In best interest of @500Startups & at request co-founder @christine_tsai, i am resigning effective immediately," he wrote.

McClure was removed from an executive role in the company a few months ago due to "inappropriate interactions with women in the tech community," co-founder and managing partner Tsai said in a statement last week that followed a New York Times report on sexual harassment by Silicon Valley venture capitalists - including McClure.

McClure published a blog post on Saturday apologizing for his actions, which he called "inexcusable and wrong."

"I would like to apologize for being a clueless, selfish, unapologetic and defensive ass," the post read.

A letter from to the firm's limited partners on Monday - posted by TechCrunch - stated that the company had investigated another report of sexual harassment by McClure.

McClure's resignation comes at a time of mounting pressure among Silicon Valley companies to address their treatment of women.

Last month, Binary Capital co-founder Justin Caldbeck resigned from the San Francisco firm after being accused of sexually harassing half a dozen women who work in tech; in a statement, he said he was "grateful" to the women for speaking up and "deeply ashamed."

San Francisco ride-hailing giant Uber has also recently been rocked by allegations of harassment. Travis Kalanick, that company's co-founder and longtime CEO, stepped down last month following an investigation into the company's culture triggered, in part, by engineer Susan Fowler, who blogged about her experiences with rampant sexism at the company.

Kelsey Cullen, the director of public relations at 500 Startups, also confirmed McClure's resignation.
