In other words, the upstarts provide products that are good enough to solve a real problem, if not "good enough" to directly displace the leading services. NetBlazr suggests that its customers use netBlazr as a supplementary service to a primary broadband connection, as no single provider can guarantee 100-percent reliability.
Over time, though, functionality increases to the point that the upstarts are able to directly challenge the market leaders. Those of you with long memories will remember that this is precisely what MCI did when it challenged AT&T in enterprise voice services. It is Skype and other VoIP services, and is what netBlazr is attempting as well.
The company offers free symmetrical 3 Mbps service, symmetrical 50 Mbps service for $60 a month on a shared basis, or dedicates service at a range of speeds from 2 Mbps to 10 Mbps for prices ranging from $50 a month up to $200 a month.
The basic idea is bandwidth at prices roughly an order of magnitude lower than commercial services available in Boston. That's a classic "disruptor" strategy.
