The couple are already known to be working under the names Archewell Productions, to create their television output for Netflix, and Archewell Audio, which is expected to produce podcast episodes under a deal with Spotify.
They total seven separate companies specifically in the entertainment industry, along with another two publishing companies and three investment firms to match their one not-for-profit foundation.
The companies appear to be a significant change of direction for the Sussexes, who have emphasised their dedication to their philanthropy and non-profit work through Archewell.
The pair appear on the paperwork for two publishing companies: Peca Publishing, which has the rights to the Duchess’s children’s book The Bench, and is thought to be named for the Spanish word for her freckles; and Orinoco Publishing, reported to house the Duke’s forthcoming autobiography.
Three other companies, Nemawashi Holdings, Baobab Holdings and RPV Holdings, are set up for investments.
The companies were each incorporated by Richard Genow, the Duchess’s long-time attorney, and Andrew Meyer, her business manager.
Most were registered on July 16 2021, and can be found in public records registered in California and Delaware.
A spokesman for the Sussexes declined to comment.
Sussexes’ growing portfolio
It is not uncommon for business leaders to set up multiple entities in the US, with experts suggesting the practice protects them from the potential failure of one company impacting on another.
They follow numerous commercial ventures for the Sussexes, both of whom have recently been announced as “impact officers” at US fintech firm Ethic.
The Duke has already taken several new roles in the US, including as chief impact officer at coaching app Better Up and one of a panel of commissioners at the Aspen Institute’s “Commission on Information Disorder”.
It is not thought the Duchess is planning a return to acting, although she has done voiceover work since becoming a member of the Royal family.
The couple have both, however, made high-profile television appearances including the Duchess performing a comedy sketch on chat show Ellen, and the Duke making a star turn on The Late Late Show with James Corden.
