New Software Tools Help Retailers Sell Easily Across Apps, Social Networks

San Francisco-based e-commerce company Stripe unveiled a set of software tools, dubbed Relay, that help retailers sell goods more easily across a variety of apps and social networks. The product also makes checkout simpler for consumers. Believing that more people are starting to buy things online, Stripe hopes to lure big retailers like Macy’s and Saks Fifth Avenue to use Relay for selling across Twitter and other consumer apps. Twitter has integrated its e-commerce platforms with Stripe, hoping that   more people buy from inside Twitter itself. Fifty million people tweet some signal of intent — “I want, I need” — every month.
