I do 'data science' for smaller businesses that would not have the resources, or really the need for a full-time in-house analytics person like me. But, one client does about 8 to 10 hours a week, another does some projects periodically, and I just added a third that I think will end up being something like a day a week.

From my perspective it spreads my risk and from their perspective it means they get access to higher-end analytical help in a more flexible package that meets their needs. Their trade-off is higher rates per hour and my trade-off is a little more variance in income.
