In 2025, former Yahoo CEO Marissa Mayer founded Dazzle, an AI assistant that builds context by scanning photos stored on user devices. The company successfully raised $8 million in seed funding during December 2025.
Why it matters
The creator believes that personal camera rolls offer deeper insight into a user's life than email inboxes, suggesting users may be more willing to grant photo access than message access.
Dazzle secured $8 million in seed funding during a round that resulted in a $35 million post-money valuation. The startup functions by scanning on-device photos while discarding sensitive personal information.
