Built in 2017, Seller Investigators is a best-in-class Amazon reimbursement service that refunds every lost dollar back to FBA sellers, in less time and with more transparency than anyone else in the industry. But we’re also more than that.

As our co-founder Lee Loree likes to say, “We want to do right by everybody in the room.” That customer-focused, people-driven approach runs through everything we do at Seller Investigators, whether it’s our commitment to communication or the clarity our tools provide. It also drives the people behind our brand. Our global network of 300+ case managers and advisors started growing after a family trip Rob Ferreira took to his wife’s native Philippines. And it hasn’t stopped since.

With 3 offices in the United States serving the US, UK, EU, Asia, and the Middle East, Seller Investigators has become a worldwide authority in the Amazon space. We were proud to join Carbon6 in 2022 as its flagship reimbursements service.
