Lei Xu
Co-founder of Workstream, where we build hiring, HR, and payroll software to help the 80 million hourly workers and local business owners in the US. Former YC founder (Emote, S16) and Xoogler (2012–2015). Proud Cal Bear.
I think about how software reshapes work, what small teams can do that large ones can't, and how AI is about to change everything again. Occasionally I write things down. More about me.
