The Salesforce1 Platform brings together Force.com, Heroku, and ExactTarget into one family of cloud services — all built API first — to help deliver apps that connect products, users, and next generation experiences. Designed for scale and speed, it provides a fast way to build apps with open APIs, back-end services, integration tools, starter templates as well as powerful developer environments; there’s no limit to what you can build.
