We've started a co-op like this to build cross platform spatial web apps (MMOs, metaverses, online virtual storefronts, etc). The project is MIT licensed but we're going after big contracts, especially trying to fill voids in the events and retail space. While things are being developed, everyone is living on a bit of runway contributed by one of the partners to make the project a reality.

If you're interested, code is here: https://github.com/xr3ngine/xr3ngine

Happy to discuss more about structure on Discord or w/e
