The OpenStreetMap license ODbL is what is known as a Share Alike license. In that class of licenses, one is granted more permissions when one shares and shares alike. If, on the other hand, one wishes to keep things for ones exclusive benefit, ones permissions are more limited, perhaps even to a null set.
Again, in very broad terms, one has more freedom if one uses the OpenStreetMap data without changing it. Combining OpenStreetMap data with other non-OpenStreetMap data sets, is an area where the obligations to share are deliberately strong. The details matter in this subject area, and it is a benefit for you to understand your obligations from the start. Please consider giving more details and holding further discussion on the legal-talk@ mailing list[1], which is the ideal location for this topic.
