Founder Profile

Sunken Stone Founder Adam Weiler Talks Amazon Expertise

E-commerce continues to grow and dominate the consumer market. And there’s no denying that Amazon is one of the  most used hubs for e-commerce. But selling through Amazon can often be a time-consuming and complicated process. From stiff competition to timed customer inquiries to distribution issues, being part of the Amazon marketplace is a major commitment for businesses.

Sunken Stone wants to make that commitment simpler and easier to handle. Through a trademarked software platform, the company helps other brands as they establish their Amazon presence. We sat down with founder and CEO Adam Weiler to discuss his team’s Amazon expertise and the question of acquisition.
