David Rosenthal ist einer der führenden Schweizer Experten für Daten- und Technologie-Recht – «absolutely stellar» heisst es bei Chambers. Er ging nicht den üblichen Weg: David Rosenthal schloss sein Studium der Jurisprudenz 1997 an der Universität Basel ab und war als Softwareentwickler, Rechtsberater und Journalist tätig, bevor er in eine der Schweizer Top-Kanzleien quer einstieg und dort unter anderem die Datenschutzpraxis aufbaute und leitete. Einer der führenden Kommentare zum Datenschutzgesetz stammt mehrheitlich aus seiner Feder. Nebst Datenrecht (inklusive DSGVO) berät er Vorhaben im Bereich IT und Digital Business und vertritt Parteien in technologiebezogenen Schiedsverfahren. Internationale Grosskonzerne zählen ebenso zu seinen Klienten wie Schweizer KMU, Startups und Behörden; er gilt als pragmatisch, effizient und lösungsorientiert. Ein weiteres Standbein von Rosenthal ist seit rund 15 Jahren die Führung von internen Untersuchungen und eDiscovery-Projekten. Er ist Sekretär des Vereins Unternehmens-Datenschutz (VUD) und der Cross-border eDiscovery Privacy & Investigations Association (CeDIV) sowie Lehrbeauftragter der ETH Zürich und Universität Basel.
