American entrepreneur and writer who co-founded the video technology company DivX in 2000 and led it as chief executive through its public listing on NASDAQ in September 2006 [IC]. Since leaving DivX he has written on the future of civilization and, more recently, on theology, first on Medium under the masthead Deep Code and since 2026 in the Deepcode newsletter on Substack. He has published as Jordan Greenhall and as Jordan Hall; on his Medium profile he writes that he changed his name back to Hall.
Career
Hall worked at MP3.com, where he was a vice president, before proposing in early 2000 that a company be built around the DivX codec [IC]. He was chief executive of DivX and later its executive chairman, and resigned from its board in December 2007 [IC]. He served as a trustee of the Santa Fe Institute, the research center for complexity science, from 2007 to 2011 [IC].
By his own account, he co-founded Game B in 2011 as a collective-intelligence effort on the problems of twenty-first-century civilization; co-founded Qualia Lifesciences (originally the Neurohacker Collective) in 2015; helped build the platform of Backfeed, which described itself as a stigmergic framework for decentralized collaboration; and has co-led the Civium Project since 2020 [TBV].
Contribution to the BioConomy corpus
Two essays published on 21 October 2026 supply the wiki’s Participation and Conformity concept. “The Primacy of the Miraculous” argues that every actual event is singular and that regularity, and with it scientific law and measurement, arises from selecting aspects of reality for a purpose. “Participatory Universalism” contrasts a universal that governs particulars by conformity to an abstract form with a universal in which particulars take part in differentiated ways, and applies the contrast to rights and markets. The wiki uses the structure of both arguments and sets aside their theological grounding. Where the concept page applies them to money, measurement and BioHub design, the application is the wiki’s construct.
Hall’s earlier interest in Backfeed’s design touches the wiki’s treatment of stigmergy, and his Game B work belongs to the same field of writing on civilizational transition that the Three Futures framework addresses. The wiki has not drawn on those writings.
Hall has not been invited to comment on how the wiki reads his work. Corrections and responses will be recorded on this page.

Provenance
Written 22 October 2026 alongside the Participation and Conformity concept page. The career facts tagged [IC] rest on Wikipedia’s DivX article, the San Diego Business Journal and the P2P Foundation wiki. The later roles rest only on Hall’s own LinkedIn profile and are tagged [TBV] until an independent record confirms them. Michael Haupt also supplied a Reddit discussion of Hall’s public profile; the page draws nothing from it, because it consists of commentary and recollection by anonymous users about a living person. Personal details in the supplied material (contact information, place of residence, the circumstances of the name change) are left out under the network’s rules for living people.
