And today, Shogun is announcing that it has raised a $10 million Series A, led by Initialized Capital, with participation from VMG Partners and YC. (The startup has now raised a total of $12 million.) The company's first product, Page Builder, offers a drag-and-drop interface to make it easier for e-commerce brands to build their storefronts on Shopify, BigCommerce, Salesforce and Magento. And there's a new product, Shogun Frontend, which allows brands to create a web storefront that's entirely customized while still using one of the big commerce platforms as their back end.
