Start9's stated purpose is a single sentence: "To eliminate the need for trusted third parties in the human/computer relationship." Everything the company ships follows from taking that literally.
StartOS is the product. The company frames it by analogy: "Just as Windows and macOS made it possible for anyone to own a personal computer, StartOS makes it possible for anyone to own a personal server." In practice that means discovering, installing and running open-source services on a machine in your own home, without an account at Start9 to use them. Remote access is handled by the project's own tooling rather than by a third party: its documentation covers StartTunnel, described as "a self-hosted WireGuard VPN for private remote access and clearnet hosting", and the company runs an onion address for its own site. Bitcoin and Lightning are a documented category in their own right, alongside the wider self-hosting catalogue. StartOS is open source, and the company links its own source repository from the front page.
The corporate record is thin but findable. Colorado's business registry lists Start9 Labs, Inc. as a foreign profit corporation whose jurisdiction of formation is Delaware, registered in Colorado on 16 July 2020 with a principal office in Denver and a status of good standing. The same registry shows an earlier Start9 Labs, LLC formed in Colorado on 31 October 2019 and voluntarily dissolved in June 2020. Because the Delaware incorporation date itself is not public, this entry gives no founding year rather than pick one of those two.
Start9's own podcast page names Matt Hill as chief executive and Keagan McClelland and Aiden McClelland as co-founders.
Hardware is sold as a convenience rather than a requirement. Start9 sells prebuilt servers and documents building your own, which keeps the operating system rather than the box as the thing that matters. That is the honest version of the sovereignty pitch: you are buying setup time, not permission.
