Hey there one of the Co-Founders of Estimote here, that makes the Sticker Beacons and coined Nearables.

Sometimes we think of Estimote Stickers as 'Tile for Developers', at least among the community that knows Tile.

Meaning, we're a developer facing platform, more B2B2C and anyone can create a digital tethering application, and any app can adopt it.

We have a big vision for the 'Nearables' concept and hope that the community can push this narrative forward together. Sometimes we think abstractly of beacons as place URLs for physical objects.

Looks like the same idea, I'm pretty disappointed that Tile is only for iOS. Looks like a good implementation of the idea in this article.
