It goes without saying that San Francisco is home to some of the most innovative e-commerce talent in the nation. San Francisco based Instacart is one of the most successful e-commerce service providers in the country. Combining the ease of digital shopping with the smiling human in the green t-shirt, providing personal shopping services has been a huge hit. But Instacart isn’t alone in the community of San Francisco e-commerce movers and shakers. While Instacart is principally a B2C platform, other San Francisco operations like Square, Faire, and Minted offer up an array of marketing and support services in the B2B sector.
