Until a few weeks ago I've never heard before of 3words, but they seems to be online from a very long time.

Another similar geo location system, if I'm not wrong created by Google but released with a liberal license (Apache) and not patent encumbered, is called "plus.codes".

Edit: according to Wikipedia they were founded in 2013, don't recall why I thought they were older...

That's nice to learn about this alternative.

I haven't worked a lot with geolocation yet. But I'm driven to it because of my geography background, and I would be mad if every service for that kind of work was closed and proprietary.
