Wouldn't it be nice if every source of company and contact information around the world was tagged with your coproate customer number? It can be like that. However, such a utopia is fleeting when you let each provider of demographic and firmographic data try to to do that match for you at variable times of the year.  At Sherwin Lake Group we have proven algorithms for matching customer data to just about any source on the internet.  The SLG matching approach is not a one-size fits all approach but rather we use our best practice algorithms with key words and tags specific to your organization and industry. If you host your analytics platform on the cloud with us then customer matching becomes fully baked into the data acquisition process regardless of the number of sources and frequency of data you use.  If you choose to host your own infrastructure and licenses, that works as well: our matching solution can be ported to most any data integration tool you work with.
