About e-Comas – eCommerce Made Simple

e-Comas (formerly The Great Wall) marketing agency was founded in 2013 by eCommerce expert Jérôme de Guigné, with the simple idea of helping brands sell products online.

We quickly realized just how many companies were struggling with Amazon, facing issues including communication, strategy, and business in general. That's when "Amazon Made Simple" was born, which later became "eCommerce Made Simple" - e-Comas.

e-Comas Amazon agency now helps major multinational brands expansion their Amazon strategies. With a hands-on approach, our experts coach brands and handle their accounts, and we also provide starting packages for beginners on Amazon.
