Brightfuse, CareerBuilder’s experimental project, has been quietly gaining ground in the business networking community. A business-oriented social networking site launched back in February 2008 has accumulated a following of around 75,000 members.Working around the premise that referral recruitment grows in popularity in credit-crunched times, it seems that Careerbuilder is investing in the networking premise to support their further work in resourcing. Compared to LinkedIn’s 27 million members, CareerBuilder’s got a way to go, but argues that it’s going for a very different demographic - senior employees with six-figure salaries. We at BB (and our clients) always like to be in on these things whilst they’re still in they’re beta/alpha/never heard of it phases and, so far, Brightfuse hasn’t really promoted itself heavily, relying on steady evolution. So, whilst it’s still very very transatlantic, it’s well worth becoming an early adopter, if only because it’s so quick and easy.
