In December 2025, Marissa Mayer secured $8 million in seed funding for her new venture, Dazzle. The AI-powered assistant is designed to build user context by scanning photos stored directly on mobile devices.
Why it matters
The development represents a shift toward local device processing for personal intelligence, as the creator argues camera rolls contain deeper context than email. By scanning images locally, the startup attempts to address privacy concerns that often limit users' willingness to grant AI access to communication streams.
Dazzle operates by scanning photo libraries stored on a user's phone to build context. The system is programmed to identify and discard specific personal information flagged by the AI as sensitive.
The players
Marissa Mayer
A former Yahoo CEO and early Google executive who is the founder of Dazzle.
Sunshine
A startup founded by Mayer that previously launched and shuttered the AI tool Shine.
The details
The application functions as an AI assistant that analyzes static images stored on a user's device to infer personal context. By processing data locally rather than scanning email or message inboxes, the startup aims to lower the barrier for users to share sensitive information with automated agents. The software includes logic designed to scrub data classified as sensitive by the model, though the underlying mechanism for this classification has not been detailed.

The Tech Race
Dazzle marks a new attempt by Marissa Mayer to build consumer-facing AI following the closure of her previous project, Shine. The startup is navigating a crowded space of personal assistants by betting that privacy-focused local processing will overcome the adoption hurdles that slowed its predecessor.
Users can expect the service to prioritize local device storage for data analysis rather than cloud-based email ingestion. The tool requires access to a user's mobile camera roll to function, replacing standard cloud-connected assistants with an image-first approach.
The takeaway
Dazzle shifts the focus of personal AI from communication logs to visual archives. Observers should monitor the startup's ability to maintain user trust as it moves beyond its $35 million valuation and attempts to scale into broader device integration.
