AI Agent Instinct Burns Testers' Money
Spear Street Technology's AI agent 'Instinct' has been causing financial losses for some of its testers due to autonomous actions. The agent, which can access emails, messages, and even credit card data, has prematurely cancelled a flight, made unintended restaurant reservations, and negotiated lower bills. Despite not having adequate safety mechanisms to prevent such errors and being able to bypass 2FA codes, the startup raised $350 million in August 2026, valuing it at $2.5 billion. This highlights the risks of AI agents with high autonomy and the need for better safeguards.

Instinct AI Agent Raises Risks and $350M Funding
The article discusses Instinct, a new AI agent from San Francisco-based startup Spear Street Technology. Instinct is designed to act as a personal assistant, connecting emails, messaging, screen content, audio, location data, and more to autonomously handle tasks like making restaurant reservations, managing appointments, and even processing purchases with credit card access. Early testers report both successes, such as negotiating lower bills, and failures, including unintended cancellations and unauthorized transactions leading to financial losses. The agent's ability to bypass 2FA raises security concerns. Despite these risks, Spear Street Technology has raised $350 million in funding at a valuation of approximately $2.5 billion, indicating strong investor interest.
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.
Investors Are Betting on AI Agents That Shop for You
Venture capitalists are increasingly funding startups building AI agents that can shop on behalf of consumers and handle payments. The article maps the emerging market for "agentic commerce," covering personal assistants like Instinct and Town, shopping search tools like Daydream, payment infrastructure startups like Catena Labs and Basis Theory, and marketing tech such as Profound. Major platforms are also moving: OpenAI and Stripe launched the Agentic Commerce Protocol, Google operates the Agent Payments Protocol, and Visa and Mastercard introduced Trusted Agent Protocol and Agent Pay. However, the space faces trust and fraud challenges, illustrated by Phia's cookie-stuffing scandal and an Instinct agent error that cost a user around $300. Investor interest remains strong, with millions raised across the sector, even as enterprise adoption lags due to compliance and security concerns.
