About the Lead Developer

Professional software developer Robert Casto worked for Amazon on their Product Advertising API team. In 2009, he and his wife began selling books on Amazon, and he created SellersToolbox in order to better organize their product inventory. After receiving requests from other sellers for his software, he decided to make SellersToolbox available to the public through R&L Software. Robert now leads a team of developers to update and improve the tools. He remains committed to helping Amazon sellers gain greater insight into their business.
