This could be really big: one force that pressures B2B startups to get acquired is that huge companies have a big salesforce with existing customers. That makes it more efficient for multiple products to agglomerate into monoliths like IBM, EMC, or Oracle.
If LeadGeni.us is successful, then it would become something like a federation of enterprise startups that share lead lists. That would in turn lead to a more modular B2B ecosystem with lots of cooperating smaller companies, more competition, and better products for everybody.
