A little more than a year after launching in the United States under the leadership of a former Proskauer Rose lawyer and restaurateur, litigation funder Therium Inc. is expanding in New York.

Therium Inc.—the U.S. arm of U.K. litigation financier Therium Group Holdings Ltd.—announced on Thursday that it has brought on William Weisman as an investment officer. Weisman, a former Gordon & Rees and Proskauer litigator, most recently worked for Liberty International Underwriters Inc., overseeing litigation matters as part of the company’s directors and officers insurance business.
