Who owns Xumo Services, LLC

One company in the researched set discloses a stake in Xumo Services, LLC, none of it sized by anyone who discloses it. Xumo Services, LLC is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Xumo Services, LLC is a Delaware registered streaming venture created by Comcast and Charter Communications in 2022 to build a shared next generation streaming platform for the cable and entertainment industry. Comcast licensed its Flex 4K streaming device and its global entertainment technology platform into the venture, which relaunched them as the Xumo Stream Box and Xumo TV, while both partners distribute the hardware to their own video subscribers: Charter to Spectrum households and Comcast to Xfinity homes. The company runs three lines of business: Xumo devices, which pair a live television experience with hundreds of streaming applications, unified search and voice control; Xumo Play, a free advertising supported streaming service carrying hundreds of linear channels and on demand titles; and Xumo Enterprise, a business to business arm that distributes and monetises free ad supported channels for content owners and advertisers. Nationwide rollout of the Stream Box began in October 2023. Xumo is run from Philadelphia and the Xumo brand itself dates back to 2011.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not

It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Xumo Services, LLC where a holder stated one, and are missing where no holder did.
