Everyone and their mom talks about network effect. And most people leverage their network the same way that mom does, LinkedIn. It's noisy. How many requests have you accepted from people you've never met or even intend to?
Conspire is changing that for me, and I've since abandoned LinkedIn (other than accepting requests from people I've met and know).
Connections on Conspire are driven off of email versus simple connectors via random invites. So when I search for someone I need to connect to it’s based off of people who actually talk to him or her and how well they know them. Techstars companies and the broader network are using it to get the warm intros needed to angels and VCs, and really anyone they need to start a relationship with.
Especially If you’re putting a round together: use it.
