Tile — the company that makes popular square-shaped tags and other technology to help people keep track of physical belongings like keys and bags — has made more recent moves to link up with chipmakers, helping it expand to wireless headsets and other electronic and other connected items as part of a wider smart home strategy. Now, Tile is announcing a round of funding of $45 million to double down on those strategies and fulfill a plan to have its technology in millions of devices by the end of this year.
