Sesame raised $250 million in a Series B round and opened an early beta of its iOS app to selected users. The company is building a personal AI agent that uses natural human voice and may later power lightweight smart glasses. Its demo voices quickly attracted about one million users and generated more than five million minutes of conversation. The funding round included Sequoia Capital, Spark, and other undisclosed backers. The beta app now lets testers explore search, text, and thinking features under confidentiality restrictions.
