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.
- Adobe Analytics reported that 41% of respondents used AI for online shopping in June 2026.
- OpenAI and Stripe launched the Agentic Commerce Protocol (ACP), while Google operates the Agent Payments Protocol.
- Profound raised $96 million in Series C funding led by Lightspeed Venture Partners.
