Sequoia Capital’s chief operating officer resigned over comments made by partner Shaun Maguire which she regarded as Islamophobic, as political debates sow division at one of Silicon Valley’s most powerful venture capital firms.

Sumaiya Balbale — a practising Muslim who has spoken publicly about how her gender, ethnicity and faith have shaped her career — stepped down after five years at the company in August. Her decision to leave was precipitated by Maguire’s social media posts, according to three people with knowledge of the matter.

Maguire, an outspoken and high-profile investor who is close to Elon Musk, wrote on X in July that New York mayoral candidate Zohran Mamdani “comes from a culture that lies about everything. It’s literally a virtue to lie if it advances his Islamist agenda. The West will learn this lesson the hard way.”
