Denver-based Wayin, the developer of social media tools, has raised $12.1M in a funding round--and hopes to raise at least $13.1M--according to a regulatory filing Tuesday. Details on the funding have not yet been announced by the company. Wayin provides tools that help companies better engage with their audience and social media, and tap into influencers who are brand advocates. The company was founded by former Sun Microsystems' chief Scott McNealy. The company has previously raised funding from U.S. Venture Partners, TIBCO Software, Wilson Sonsini Goodrich and Rosati, and a long list of angel investors.
