Dazzle AI

Dazzle AI Inc. is a Palo Alto, California-based artificial intelligence company founded in 2025 by entrepreneur, executive and technologist Marissa Mayer, formerly of Google and Yahoo. The company states its mission is to close the gap between what people want to do and what they can do with AI, developing tools intended to make technology simpler, more approachable and useful in everyday life.

According to press coverage citing TechCrunch, Dazzle is developing an AI personal assistant aimed at the consumer market. Job postings on the company's site for an iOS developer and an AI researcher indicate plans for mobile availability and in-house work to architect, develop and evaluate AI models. As of the December 2025 seed announcement, the company had not yet launched a product and said its first launch was expected in the coming months.

Dazzle emerged from Sunshine (originally Lumi Labs), a consumer technology startup Mayer founded in 2018 that developed an AI-assisted contact management app. In September 2025 Mayer notified Sunshine shareholders that the company's assets would be sold to Dazzle, a newly incorporated company with committed funding; approximately 99% of shareholders approved, Sunshine investors received a 10% stake in Dazzle, and roughly 15 Sunshine employees were expected to move to Dazzle.

Founding story

Dazzle AI was incorporated in 2025 by Marissa Mayer, who was Google's employee number 20 — where she worked on the Google Search interface, Google Maps and AdWords — and later served as Yahoo's CEO from 2012 to 2017, overseeing the sale of Yahoo's core assets to Verizon. Dazzle was formed as Mayer wound down Sunshine, her 2018-founded consumer AI startup, whose assets were sold to the newly incorporated Dazzle with the approval of about 99% of Sunshine shareholders in September 2025. Mayer has said the company's premise is that foundation models have become reliable infrastructure and that the new frontier lies in applications built on top of them.

Business model

Dazzle AI is building application-layer software on top of existing foundation models rather than competing on model development, with a stated focus on usability, workflow integration and trust. No pricing or commercial terms have been disclosed publicly.

Traction

As of the December 2025 seed announcement, Dazzle AI had not released a product; funding was earmarked for team expansion and development ahead of a first launch. Roughly 15 employees from Sunshine were expected to transition to Dazzle.

Latest developments

On December 23, 2025 Dazzle AI announced an $8 million seed round at a $35 million post-money valuation led by Kirsten Green of Forerunner, with Kleiner Perkins, Greycroft, Offline Ventures, Slow Ventures, Bling Capital, Amino Capital and the Acquired Wisdom Fund participating; SiliconANGLE also lists Mayer as an investor in the round. Proceeds are intended to expand the team and support the first product launch, with more information about the service expected in early 2026.
