London-based Ning-competitor Webjam has secured a further $1.9 million (1.2M Euros) in funding led by initial investor I-Source. The A round extension won’t match Ning’s millions, but it will see Webjam execute some new functions, including allowing organisations to create branded online communities (the so-called B2B2C market). That’s slated for a full launch in September as a SaaS fee-paying version.
