The landscape of alternative legal service providers (ALSPs) is changing, fast, and Ed Sohn is mapping the front of the new terrain. Ed managed Thomson Reuters’ Pangea3, the legal managed services business that pioneered the global outsourcing of legal work to offshore legal professionals. This year, that business sold to big four accounting firm Ernst & Young, which fellow Fastcase 50 honoree Bob Ambrogi predicts should be a wake-up call for law firms, as global accounting firms are shifting towards combining “people, processes, and technology to deliver legal services both effectively and at greater value.” Alongside co-author Joe Borstein, Ed covers innovative technologies and businesses in the legal industry for the must-read Alt.Legal column in Above the Law.
