# Jack Dorsey
Jack Dorsey (born in 1976) is an American entrepreneur best known as the co-founder and CEO of the social networking site Twitter. He is also a founder and CEO of mobile payment company Square. Recently, Dorsey has become a sort of a crypto celebrity based on his strong support for the Bitcoin and the Lightning Network. Dorsey has background in programming and web development which helped him with founding Twitter back in 2006. Prior to this, he worked at the Missouri University of Science and Technology and designed cab dispatch software. Dorsey considers Bitcoin “the native currency of the internet”. Yet, according to him, the internet still needs a more accessible global financial infrastructure, which is why he recently announced his plans to assemble a team which will be solely dedicated to helping the crypto ecosystem and the community existing within it.
