Sunshine, the consumer AI startup founded by Marissa Mayer in 2018, is shutting down and selling its assets to a new company called Dazzle, which Mayer has incorporated. In an email to shareholders, Mayer announced that 99% of them have agreed to the sale, which is intended to pave the way for a new AI personal assistant. The decision comes after a series of challenges faced by Sunshine, including privacy concerns related to its products. The startup's employees are expected to transition to Dazzle, which aims to build on the momentum of Sunshine's initial offerings. Mayer, who has a notable background in tech, including her tenure at Yahoo and Google, expressed pride in the team's accomplishments and optimism for future opportunities.
