I’ve had few posts recently on an Estonian startup Inner Circle, planning to launch a new social networking tool. This is it – introducing here PosterBee, the new crap-free (FarmVille- and optionally even ads-free) private socializing tool, developed by Allan Martinson’s company Inner Circle, co-funded by Estonian Development Fund.

So what is it? Looking at the private beta, my first impression is that PosterBee is very simple in terms of functioning and design, but also hassle-free. Before even creating any new groups, you can tell that it truly takes only about few seconds. 

„Feel free to create groups, message people, plan events or share files and photos – without anyone outside your group knowing,“ PosterBee tells me. Ok. Question is, how they make everyone to join this new environment. Even if groups are currently using traditional e-mail services, it might be difficult to change their communication paradigm, if they are used to it. But I guess PosterBee can do a lot here by wise and well-targeted marketing.

One of the most interesting news coming along with PosterBee is group communication with wide range of totally different tools: web, e-mail, SMS and even voice(calls). Practical benefits of this I can not even imagine yet.

Another perhaps important feature the new tool is offering is linking your account with other social networks. You can share things with your small and private PosterBee group, but at the same time distribute your stuff to your Twitter, Gowalla, Facebook, Foursquare and some other „pipes“.

Andrus Purde from the PosterBee team tells me that he expects to see different clubs, condominiums, alumni groups, parent unions and other groups (currently using primarily mail groups) testing and using new tool.

I must admit that I am a bit worried about how this thing monetizes itself and stands out from the tight competition.

Will I be using PosterBee any time soon? Probably. I have to organise my church choir friends one way or the other anyway.
