To drive the fast-paced development of what is known to be the most comprehensive social media management platform today, Shoutlet today announced an accumulated $6 million in series B funding. The round was led by existing investor, American Family Insurance, who had invested $3 million in the company in the previous round.

Other series A investors including Origin Ventures and Leo Capital Holdings also participated in the round. Shoutlet is now rolling its double-digit growth and product development plans.

“Our growth has been extraordinary and today’s funding announcement will allow us to implement our visionary ideas for social media management at an even faster pace,” said Jason Weaver, CEO of Shoutlet. “As we see more and more brands turning to social media as a channel to communicate with their customers, we are excited to be at the forefront, delivering the technology that makes it simple to engage with customers as well as ensuring those engagements are effective.”

The Shoutlet enterprise-wide social media platform is an integration of Facebook and Twitter management, Social CRM and widgets, to generate promotions, coupon and sweepstakes. This is part of American Family’s social media strategy to help independent contractors individually engage with Facebook customers. Moreover, the platform also offers mobile marketing, social commerce, and real-time analytics to keep track of the effectiveness of ongoing campaigns.

Shoutlet’s feature that sets it apart from many other products of its kind is the permissioning tool. This allows corporate-level managers to send a directory of pre-approved content for employees to use at their disposal, and offers transparency of the success of what individual employees choose to share in behalf of the company. This gives managers a better grasp of the efficacy of individual employees’ discretion.

Shoutlet’s platform aims at helping dramatically growing enterprise-level brands to build, engage and measure all of their social media communication in a comprehensive and handy interface. The platform eliminates the hassle of multifaceted structures in managing different social media as well as incorporate them to existing marketing campaigns for maximum promotion.
