Kalai, Rosen & Co. is one of Israel’s leading boutique law firms, known for delivering high-level legal representation with a focus on commercial and public interest litigation.
Founded over a decade ago by attorneys Hagai Klalai and Ohad Rosen, the firm was established with a vision to serve individuals, businesses, business-people, nonprofits, and public institutions—guided by values of integrity, social responsibility, and protection of human rights – with a wining attitude.
Over the years, the firm has earned its strong reputation for representing clients in complex commercial disputes involving both public and private companies.

With a team of over a dozen attorneys, we offer broad experience across a large range of legal disciplines, thanks to diverse academic, professional and cultural backgrounds.
Our attorneys have led hundreds of class actions and derivative suits, and have been at the forefront of precedent-setting public law cases that have helped shape Israeli jurisprudence.
We are particularly proud of our role in a series of landmark constitutional petitions argued before the Supreme Court in recent years—cases that have driven meaningful legal and societal change.
For several consecutive years, Klalai, Rosen & Co. has been consistently ranked among Israel’s top law firms in litigation, administrative law, class actions, defamation, and environmental law.
