Former Yahoo CEO Marissa Mayer is pulling the plug on Sunshine, her consumer AI startup that struggled for seven years to find its footing. The assets are being sold to Dazzle, a new AI company Mayer just incorporated with plans for an AI personal assistant. It's a strategic pivot that signals Mayer's bet on the current AI boom after two product flops.
The end came quietly for Sunshine, but the beginning of something new might be louder. Former Yahoo CEO Marissa Mayer sent a brief email to shareholders on September 17, announcing that her seven-year consumer AI experiment was over. The startup's assets would be sold to Dazzle, a freshly incorporated AI company that Mayer founded with what sources describe as "committed funding." Within two weeks, 99% of shareholders had signed off on the deal, according to sources close to WIRED. The swift approval suggests investors were ready to move on from Sunshine's rocky journey. Major backers including Norwest Venture Partners, Felicis Partners, and Ron Conway's SV Angel all signed on, along with co-founder Enrique Muñoz Torres. Mayer herself, as the largest shareholder and investor, was essentially selling to herself - a corporate restructuring that lets her pivot without admitting total defeat. The timing isn't accidental. While Sunshine struggled to gain traction with consumer apps, the AI assistant market has exploded since ChatGPT's launch. Sources tell WIRED that Dazzle will target "a new kind of AI personal assistant," putting Mayer in direct competition with OpenAI, Google, and every other tech giant racing to build the next generation of digital helpers. It's a familiar pattern for Mayer, who's built her career on spotting trends early. As employee number 20 at Google, she designed the interface for Google Search and helped develop Google Maps and AdWords. Her eye for user experience made those products household names, even if her Yahoo turnaround attempt from 2012 to 2017 couldn't revive the fading internet giant. Sunshine's story reads like a cautionary tale about consumer AI timing. Founded as Lumi Labs in 2018, the startup raised $20 million in venture funding plus Mayer's personal contributions. The first product, Sunshine Contacts, launched in 2020 with AI that could identify and merge duplicate contacts in your phone. The concept seemed smart - using Mayer's own networking challenges as inspiration - but the execution sparked immediate privacy concerns. The app was to automatically add home addresses to contacts, even for people who hadn't signed up. Privacy advocates called it a violation of user trust, and adoption never recovered. The company tried again in 2024 with Shine, a photo-sharing app that sources describe as "widely viewed as a flop." Two strikes in six years left Sunshine without a clear path forward, while the broader AI landscape shifted toward conversational interfaces and large language models. Now Mayer gets to start fresh with Dazzle, bringing roughly 15 Sunshine employees into what sources expect will be a much more focused AI play. The name change alone signals the shift - from Sunshine's consumer-friendly branding to Dazzle's more enterprise-ready positioning. It's a smart move that acknowledges how the market has changed since 2018. Consumer AI apps face brutal competition and user acquisition costs, while AI assistants have proven their value in both personal and professional settings. Copilot integration across Office, Bard evolution into Gemini, and ChatGPT success have shown there's real demand for sophisticated AI helpers. The question now is whether Mayer can leverage her design expertise and Silicon Valley connections to build something that stands out in an increasingly crowded field. Her track record at suggests she understands how to make complex technology accessible to mainstream users. But the AI assistant space moves fast, and Dazzle will need to move faster.
