Also to note it was mentioned in the presentation, that Tiles estimated 2021 revenue to be $120m without supply chain constraints, thats 50% y/y growth.

Many are calling out Tiles selling out as a sign of desperation from Apple & Samsung's entry but the points raised by Chris are pretty fair and show that this is rather an aggresive acquisition to establish dominance at the infancy of an emerging market segment.

Why Tile

And, while Tile already has impressive reach, they are just getting started. The category they pioneered is about to get a whole lot bigger — we believe the launch of the Apple AirTags is the tipping point where all the devices you care about will become location-enabled. While it may sound counterintuitive, or even a bit corporate-speak, that competition from a platform giant is a good thing, we genuinely believe it is one of the best things ever to happen to Tile.

From our own experience pioneering the location sharing category (we were the first ever location sharing app on the market), we saw how the launch of Find My Friends brought our category mainstream — we had triple digit growth rates after Apple entered our space. An even more relevant example is the AirPods. If you’re like me, you might remember having an old Jawbone bluetooth earpiece back in 2010 — it seemed like the market would take off, but it just….didn’t. That is,until Apple launched the AirPods. As you can see from the chart below, the industry grew by over 300x in just 5 years, and Apple has lost market share every year since launch. The AirPods were the best thing that happened to all the other companies in the space.
