Driven by artificial intelligence and human empathy

Founded in 2014, x.ai makes an artificial intelligence personal assistant who schedules meetings for you. We’re backed by blue chip investors, including IA Ventures, Firstmark, and Two Sigma Ventures, and located in New York City.

We’re a hardcore technology company, developing invisible software. We build our business sustainably through passionate and loyal customers—and every single team member, scientist or not, has a mission of delivering exceptional customer service at all times.

“I came up with the idea for x.ai after I went through the enormous pain of manually scheduling 1019 meetings in 2012, of which ~670 had updates and or were rescheduled at least once. Anybody who goes through that amount of pain will try to find a way to remove it.”
