About Us

QEDIT enables companies to accelerate growth, mitigate risk and monetize insights via regulatory-compliant, cross-organizational data collaborations.


QEDIT was founded by a world-class team of accomplished tech entrepreneurs, researchers and developers, and boasts a dedicated staff of industry experts and professionals who love what they do. Overseen by a Scientific Advisory Board comprised of renowned scholars in advanced cryptography, QEDIT is passionate about industry and academic forces working in tandem to drive innovation forward — that’s why we helped launch ZKProof, a community-driven initiative that seeks to mainstream zero-knowledge proof (ZKP) cryptography through a global standardization process.


QEDIT’s recognition on the global stage has been earned, and we’re proud of our collective achievements, which include being featured on Crunchbase’s top 50  hottest global tech companies of 2019, and Business Insider’s list of the 35 hottest Israeli Startups of 2020. QEDIT is also proud to have been recognized by the World Economic Forum as a Technology Pioneer, and was recently selected to join an elite Defense Advanced Research Projects Agency (DARPA) research project focused on broadening the purview of ZKP cryptography for industry and government.
