The career trajectory of Dan Rabinowitz is in many ways typical of what you'd expect for someone making their way in the Washington, D.C. legal market. He did a stint as a litigation associate at Sidley Austin, trial work at the DOJ, and moved in-house to government contractor Booz Allen. But after doing some additional work in-house at a data analytics company, Rabinowitz was inspired to take on a less-traditional role for a D.C. lawyer—that of a start-up founder.
