Lithium Technologies has issued $5.6 million in shares to power its acquisition of Social Dynamx.

Lithium helps brands build social networks that can be used to drive sales and marketing, inform product development, and improve customer service. The idea is that corporations with large user communities and heavy product support needs can engage their most passionate fans to build brand nations.

Social Dynamx’s platform monitors social activity to help large businesses stay tuned in to relevant online conversations and manage their customer care. With this acquisition, Social Dynamx will become part of Lithium’s suite of solutions under the heading Lithium Social Web.

Lithium closed $53.4 million in January for its fourth round of funding (DD-sized Series D…). That funding was raised to expand the company into new verticals, expand internationally, and grow Lithium’s “digital agency ecosystem.”

The most recent offering lists investors from Shasta Ventures, Emergence, Benchmark and New Enterprise Associates. These firms all participated in the January round, as did SAP Ventures, DAG Ventures, Greenspring Associates, and Tenaya Capital.
