How a Texas vegan cheese-maker used Claude and Manus to fight back against a big shipping company

AI isn’t all about automating core business functions at Fortune 500 companies. Small and medium-sized businesses can also use AI to optimize, economize, and in some cases compete more effectively against much larger rivals.

She discovered that the company had paid $250,000 more for shipping than planned. Hiring new employees to research and fix the problem wasn’t in the cards. So Maitland turned to Anthropic’s Claude. “I handed it a year of invoices and a contract,” she tells Fast Company in an email exchange, “and it found patterns I would have needed a forensic accountant to surface, which would have been time-consuming and expensive.” She says the carrier’s shipping invoices run hundreds of pages per week, with fees layered inside fees. “Most shippers don’t have the time or tools to audit them,” Ma
