I've co-founded three companies (www.futurescaper.com, www.podaris.com, and www.imatest.com, to a much lesser extent), all of which have employed mathematicians on at least a part-time basis. If you're doing fancy parametric constraints-based modelling systems, analysis of n-dimensional causal graphs, or analysis of digital imaging systems, then a robust mathematics background can really help. Non of our hires have been been pure mathematicians, inasmuch as we've needed them to also be able to code. But I can easily imagine that larger companies pursuing similar domains ought to see the value in having purer mathematicians on their payroll.
