Founded in 2015 as a subsidiary of Alphabet Inc., Sidewalk Labs' mission was to blend technology and urban design to tackle major urban problems like sustainability, affordability, and efficiency. The company was best known for its ambitious but ultimately canceled Quayside project in Toronto, which aimed to build a high-tech neighborhood from the ground up. Throughout its operation, Sidewalk Labs developed various products and systems related to urban mobility, infrastructure, and public services. In 2022, the CEO announced that Sidewalk Labs would be folded into Google, with its core team and products focused on urban sustainability becoming part of Google's climate-related efforts.
