When evaluating data mining service providers, consider more than just the price of that service, and see if they grasp your true business needs. A good team needs to be able to describe its method in layman's terms, be flexible with the data sources and deliver valuable information, and not just a report dump. If your datasets have information about customers or other company information, security and confidentiality are also key. Inquire about previous work, methods of communication, estimated duration, and how they will be communicated. If you need a particular sort of analysis, and Datalance's experience and approach are similar, you might want to include them in your short list.
