In-Depth Profile

Early Life and Education

Jed McCaleb was born in Fayetteville, Arkansas, on June 8, 1975. He spent his childhood in Little Rock, Arkansas, where he developed an early interest in technology. He attended the University of California, Berkeley, but left before completing his degree, choosing to pursue hands-on projects in software development. His time at Berkeley exposed him to early discussions about cryptography and peer-to-peer networks, which would later influence his ventures.

Rise to Success

McCaleb's career is marked by a series of groundbreaking projects. In 2000, he founded MetaMachine Inc., releasing the eDonkey2000 application, a peer-to-peer file-sharing service. This platform became one of the largest file-sharing networks of its time, with over 4 million active users.

In 2010, McCaleb founded Mt. Gox, the first major Bitcoin exchange, which quickly became the dominant platform for Bitcoin trading. He sold Mt. Gox in 2011, before its collapse in 2014. Following his time at Mt. Gox, McCaleb co-founded Ripple (OpenCoin) in 2012. He served as CTO of Ripple until 2013. Due to differing visions on the future of Ripple, he left the company and co-founded Stellar in 2014. Stellar aimed to provide financial services to the unbanked and facilitate cross-border transactions. In 2021, McCaleb founded Vast, an aerospace company focused on developing artificial gravity space stations.
