Dazzle AI

Dazzle AI is a Palo Alto consumer-AI startup founded by former Yahoo CEO Marissa Mayer that aims to close the gap between what people want to do and what they can actually do with AI. Emerging from the assets of Mayer's earlier venture Sunshine, Dazzle is building a consumer-facing AI application - described as a next-generation personal assistant - and raised $8 million in seed funding in December 2025 at a $35 million post-money valuation, led by Forerunner's Kirsten Green.
