SocialChorus, an online marketing platform, had closed USD2.5 million in Series A funding. The total amount raise so far reached USD8 million. A new investor was added to the San Francisco-based start up firm. The new investor included in the company was Windforce Ventures Online. New funds were also expected to be received from its existing lead investor, Kohlberg Ventures.

The online marketing platform said that it achieved more than 350% growth in new clients in the last year. SocialChorus also took in Brad Klaus, ex-CEO of referral marketing platform Extole, as the company's new Chief Revenue Officer.

During the earlier times of social media marketing, firms had to find popular bloggers, send them coupon codes to a promotion and hope for the best outcome.

Approximately 200 advocate marketing campaigns use the company's cloud-based platform. SocialChorus clients include AT&T, Kia Motors, Toyota, Peet's, Windows Phone and Outback Steakhouse. The platform has recently integrated mobile optimization, LinkedIn integration and automated social engagement detection to its offered products and services.
