Y Combinator Unveils Locus Founder, an AI Agent for Building Businesses by Text

Y Combinator has revealed Locus Founder, an AI agent that lets users send a business idea through iMessage, SMS, or Telegram and have the system handle the process of building and operating an internet business. According to CoinDesk, the agent was launched Monday and can conduct market research, create branding, deploy websites, source products, and run marketing campaigns.

The development matters because it connects two fast-moving areas of technology: autonomous AI agents and crypto-based payments. Instead of stopping at research or content generation, Locus Founder is designed to sell products or services and settle revenue, making stablecoin infrastructure part of the operating layer for an AI-run business.

CoinDesk reported that the system uses more than 40 paid data APIs for market research and can build full-stack websites. It can also run outbound email and social media campaigns, including short-form video ads posted on Meta platforms, based on the company’s blog post cited by CoinDesk.

Payments are a core part of the product. Locus Founder accepts USDC, the dollar-pegged stablecoin, as well as card payments. Its payment system runs through Pay With Locus, described as non-custodial wallet infrastructure with spending controls and auditability for AI agents.

When a sale is made, CoinDesk said Checkout With Locus settles funds directly into the agent’s Locus wallet. The company presents the system as a vertically integrated setup in which an AI agent can research, build, market, sell, receive funds, hold money, and spend it with human oversight available through the underlying infrastructure.
