SocialFlow, a US-based social media service provider, has raised $7.75m of what could be a $10m series B round, according to a regulatory filing first identified by news provider Fortune.
In April 2011, SocialFlow raised $7m in its series A round from a consortium of publishers.
Japan-based internet holding company Softbank led the A round, and the consortium also included SocialFlow’s incubator, Betaworks, AOL Ventures, the corporate venturing unit of US media group AOL, and venture capital firms Softbank NY, RRE Ventures, High Line Venture Partners and SV Angel, as well as individual investors.
