9So who builds this thing? Where does it come from? What’s the history?
11−Today, Urbit is built and maintained by three organizations, a community of contributors and core developers, infrastructure (star) operators, and governance (galaxy) node owners.
11+Urbit is an open-source project that anyone can work on. The Urbit Foundation, a non-profit organization, is charged with shepherding the network toward a successful future. [Tlon](https://tlon.io/) was the first private company founded for the purposes of working on Urbit, back in 2013. Now there are several more.
13+These include [Uqbar](https://uqbar.network/), [Holium](https://www.holium.com/), [Tirrel](https://tirrel.io/), [Native Planet](https://nativeplanet.io/), and others. Beyond that, an ecosystem has sprung up around Urbit that includes [funds](https://assembly.capital/), [DAOs](https://labyrinthdao.io/), and [publications](https://marsreview.org/). And of course there are many community contributors, many of whom have received [grants](https://urbit.org/grants) from the Urbit Foundation.
13Let’s talk first about these individual groups within the Urbit community, then about the history of the project and how it came to be.

17−There are currently three principal organizations involved in Urbit’s development and maintenance: Tlon, Urbit.live and the Urbit Foundation.
19+The Urbit Foundation was formally established in 2021 when it split off from Tlon. The Foundation runs the grants program, maintains [urbit.org](https://urbit.org/), the [network explorer](https://network.urbit.org/), [education](https://developers.urbit.org/courses/hsl), and it organizes Urbit events like [Assembly](https://assembly.urbit.org/). Recently, the Urbit Foundation has also taken the lead on Urbit's [core development](https://roadmap.urbit.org/).
19−Tlon has been around since 2013 or so, and is primarily focussed on the development of Urbit OS and its user experience. Urbit.live was started in 2018 to make the on ramp into Urbit as easy as possible. Both companies contribute regularly to the code base.
21+[Tlon Corporation](https://tlon.io/) was founded in 2013 to bootstrap Urbit. Currently it is building a hosting service and a suite of Urbit applications, including [Groups](/applications/~sogryp-dister-dozzod-dozzod/groups), [Talk](/applications/~sogryp-dister-dozzod-dozzod/talk), and Small Talk.
21−Tlon was originally granted about half of the Urbit ID address space, and has used that to fund its operations so far. Over time, Tlon plans to offer hosting and services to make using Urbit as easy as possible.
23+[Tirrel Corporation](https://tirrel.io/) was founded in 2021, it creates tools for creators to build their communities, share content, and make money. most notably the subscription application [Studio](https://urbit.studio/). They also produce the Urbit desktop environment Scene.
23−Urbit.live started selling Urbit IDs very early once that became possible, and also plans to offer services within the Urbit ecosystem.
25+[Uqbar](http://uqbar.network), founded in 2022, is working on an L2 blockchain on Urbit. Uqbar uses Urbit’s native language, Hoon, for its smart contracts, enabling developers to write smart contracts and decentralized off-chain applications that utilize them all in one language and stack. They have also produced the Urbit apps Pongo, Pokur, and [Blog](/applications/~hanrut-sillet-dachus-tiprel/blog).
25−The Urbit Foundation was formally established in 2021. The Foundation runs the grants program, maintains urbit.org, the network explorer, and organizes Urbit events like Assembly.
27+[Holium](http://holium.com), founded in 2022, builds Realm. An Urbit-backed desktop (and soon mobile) environment focused on collaborative computing. Realm allows you to create Spaces in which a group of people interact with the same applications, e.g. shared dictionary, meme library, group chat, voice chats, shared cursors, code editors, web browser.
27−The community of contributors and core developers has been steadily contributing to the code base since before Tlon existed, and they’re still going strong. They can primarily be found on Urbit itself, in the Urbit Community ([~bitbet-bolbel/urbit-community](/groups/~bitbet-bolbel/urbit-community)), the urbit-dev mailing list and on GitHub.
29+[Quartus](http://quartus.co/), founded in 2022, provides custom tooling stacks for Urbit companies. They produce applications such as [Keep](/applications/~dister-dozzod-dalten/keep), a recovery tool for Urbit computers and Urdl, an Urbit version of the popular Wordl game.

31+[Zorp](http://zorp.io), founded in 2022, works on Zero Knowledge proofs of Nock.
31−At the beginning, Urbit was just a few people with the right combination of imagination and discipline to try to rebuild computing.

40+The Urbit Foundation's split from Tlon becomes complete, and the Foundation organizes [Urbit NYC](https://urbit.org/groups/~ladtem-filmyr/urbit-ny-week) and [Assembly 2022](https://assembly.urbit.org/) in Miami while launching a highly successful education project, new developer documentation and many other things. Read the Foundation's full annual report [here](https://storage.googleapis.com/media.urbit.org/site/overview/~2023%20Retrospective%20%26%20Plan%20PUBLIC.pdf).
