Assistly, a startup that’s looking to provide businesses with a robust platform for engaging customers on everything from email to Facebook and Twitter, has just raised $2.2 million in series A funding from True Ventures and Howard Lindzon's new investment fund Social Leverage. We first caught wind of Assistly back in October when its founding members left AOL in tandem, and then reported on the startup when it came out of stealth and added Mark Cuban and David Liu as advisors. Assistly, which is in private beta until June, has developed a platform that offers a robust customer service application with self-service ease of use. A key part of the Assistly platform is a case management features that organizes all of the information related to your customer support conversations, including notes, status, assignment and priorities.
