There is a tremendous amount of additional information that you can use Maltego to gather. Spend some time trying to obtain more domain-related information. Test some different transforms, even if one transform fails to gather a particular type of data, another transform may succeed in gathering it. Also you can use Maltego to discover other domains that may be related to the company. Perhaps, they have example.com and example.org that have different mappings, so take the time to explore and gather all the information you can.
