What If We Are Selling To A Unique Market? Do the above services not meet your needs? It’s amazing what kinds of lists and data overseas firms can build for you , although you will have to accept that the quality may not be great. Elance. com is an excellent resource to post projects and receive multiple bids from overseas vendors. Blog Post On List Building Brian Carroll has a nice post here to help you think about building lists: http://blog.startwithalead.com/weblog/2007/03/would_you_buy_t.html DataSalad: Fresh B2B Marketing Data When running the Salesforce.com lead generation team, I wish I would have had lists of the customers of competitors such as Oracle, Siebel and NetSuite. In 2008 I founded DataSalad with Brian Mackley (CEO, DeepWWW), because he had a technology that could produce those kinds of lists, and we were both tired of all the junky lists and data sources being hocked and resold. Another ex- Salesforce.com colleague, John Bogard, joined us as a partner in 2010. DataSalad has lists of companies that are clients of and use specific applications —such as a list of customers of Salesforce.com, a list of Webex customers, and much more. Where The Lists And Data Come From People and companies leave all kinds of “digital fingerprints” on the Web. DataSalad generates the list of application-specific customers by crawling dozens of different sources of online information and databases, such as job boards and discussion groups. Then the technology interprets these fingerprints and fragments to reassemble the data together into full records. The data is verified and crosschecked prior to being added to our database.
