AI Assistant Tab Launches with $300M Valuation
Personal AI assistant startup Tab has emerged from stealth with a $300 million valuation, according to an announcement on Tuesday. The company, founded by Brennan Erbz, Stafford Schlitt, and Ammar Amdani, offers a consumer AI assistant accessible via iMessage and WhatsApp. Users can text tasks like grocery ordering or gift finding, and Tab handles them by leveraging its own phone number, computer, and wallet. Investors include SV Angel, Valar Ventures, and American Spirit. The founders emphasize trust and privacy, stating that user data is never used to train AI and that the card details are stored in a vault inaccessible to Tab. The startup is growing via word of mouth and plans to launch a new product soon. Tab enters a competitive consumer AI market alongside Instinct and Meta's Muse.

Instinct AI: The $10B Personal Agent Shaking Up Silicon Valley
Instinct, an invite-only personal AI agent for iMessage and WhatsApp, is generating significant buzz in the AI community, with reports of a valuation of $10B in funding talks. Founded by 23-year-old Noah Shinn, known for the Reflexion paper, Instinct has rapidly progressed from seed funding at a $50M valuation in April 2026 to a Series A at $500M and a Series B at $2.5B, all within months. The agent integrates with Google Workspace, can make calls, book appointments, order food, and interact with other Instinct agents via a 'Trusted People' network, positioning itself as a multi-purpose personal assistant. While praised for its ease of use and powerful features, concerns remain about data security and potential misuse of payment information, leading the reviewer to adopt a cautious approach by limiting access to a spend-limited card.
Instinct AI Hits $2.5B Valuation in Weeks
Instinct, a personal AI assistant founded by Noah Shinn (author of the Reflexion paper), jumped in valuation from roughly $100M to $2.5B within weeks after successive funding rounds led by Kleiner Perkins, Benchmark and Index Ventures. The product remains an invite-only, free beta with no disclosed revenue or user numbers; investors are betting it could become a “personal AI gateway.” The article highlights the technical moat as hiding complex agent self-correction and orchestration behind a simple text/call interface, and raises concerns about the deep permissions such agents require (inbox, payment methods, calendars), recommending spending caps and confirmation gates as mitigations.
Instinct raises $350M at $2.5B valuation
Instinct, a consumer-facing AI assistant launched within the past year and operated by Spear Street Technology, has raised a total of $350 million following a recent Series B that included a $250 million tranche, valuing the startup at $2.5 billion. The round was co-led by Index Ventures and Benchmark. Instinct — currently in private beta and led by founder Noah Shinn — lets users connect apps and devices and interact via text and calls. The product has attracted enthusiastic early users as well as controversy over privacy and permissions. The company’s founder publicly highlighted user use cases on social media.
