Xochi Birch OBE (/ˈsoʊtʃi/) is an American computer programmer and entrepreneur in San Francisco, California.

She is the co-founder of several companies since 1999, most notably the online social networking website Bebo, with her husband Michael Birch.

[6] Their current project is The Battery, an exclusive members club[7] in San Francisco, with their vision stated as “to create a culture where inspiration is embraced, diverse communities come together and egos are checked at the door.”[8] Birch is a supporter of the non-profit organization charity:water, having given over $4 million to the organization.

[9] For her 40th birthday she asked people to donate to charity:water instead of giving her a gift; the campaign raised more than $20,000.

In 2014 she and Michael bought a run-down pub and manor house in the small village of Woolfardisworthy, Torridge in North Devon.
