I wonder where did you find here the completely different direction?)
Even if founders think that their project will eventually be able to replace Linkedin, maybe you haven't fully understood in this project? I think the guys know better who is their competitor.

Linkedin is just a social network. albeit a professional but just a social network. AskBrains this platform is a place where a client and a customer can make a deal, where a startup will find an investor and so on. I understood correctly? AskBrains is not a place for idle chatter as in Linkedin.
