The sleep tracking device that raised investment from Dick Costolo is now available to buy in Europe
The device measures lots of different factors in a room to give users an overall sleep score. It stores data on temperature, noise, humidity, light, movement, and air quality. Sense then puts that data together to examine a user's total sleep quality and suggest improvements.
Hello, the company that makes the Sleep trackers, recently raised $30 million (£21 million) from investors including a fund owned by the government of Singapore. Overall, including its Kickstarter proceeds, Hello has raised over $40 million.
Another investor in the recent raise is former Twitter CEO Dick Costolo. This isn't the first time that Costolo has invested in a startup, though. Back in April he invested in notification platform Projector as part of its $4.5 million (£3.1 million) round.
The Sense sleep tracker can be ordered through Hello's website.
