Stewart Rauner, Senior Financial Advisor
In his role as Managing Director, Stewart Rauner advises clients in the Broadband, Cable, Media and Communications Technology sectors, providing Merger & Acquisitions, Private Placement and Financial Advisory services. In addition, Mr. Rauner has geographic responsibility for Katalyst’s business affairs in Israel.

After completing his academic studies (B.A. Columbia University, 1978; J.D. Harvard Law School, 1982), Mr. Rauner spent nine years working as an investment banker and economic development professional in New York, focusing on M&A work and project finance. During this period, he also completed part-time postgraduate studies in corporate finance and taxation at New York University.

In 1991, after serving as Vice President of Investment Banking at Prudential Securities, he moved to Israel, where he lived for 11 years, before returning to New York in December 2002.

From 1991-95, Mr. Rauner worked as an attorney at two of Israel’s leading corporate law firms, Herzog, Fox & Neeman and I. Fischer & Co. (now Fischer, Behar, Chen & Co.), both in Tel Aviv, where he utilized his investment banking background to specialize in venture capital investments and Nasdaq offerings for Israeli technology companies.

In 1996, Mr. Rauner established Broadband Associates, a boutique advisory firm focusing on financing, strategy and US business development (including strategic investment) for early-stage Israeli and European-based communications technology companies. Over the following seven years, he successfully executed value added commercial arrangements and financings for companies engaged in a wide range of leading-edgetechnologies, including carrier, enterprise and broadband Voice over IP; cable data and telephony; softswitch; network management/OSS; communications semiconductors; VoD/IP-TV; freespace optical wireless communications; and wireless base station technologies. Recent projects have involved several new areas, including storage networking, optical components, Infiniband and related interconnect technologies.

Mr. Rauner has been especially effective introducing and financing new technologies and products to be deployed by the leading US and international cable operators, and has been active in industry forums including CableLabs, SCTE, NCTA and CTAM.

Through the late 1990’s, Mr. Rauner played a key role in financing, building and selling three Israel-based companies with exits before the market downturn—Internet Telecom, a provider of core enabling technologies for Voice over IP (sold to Terayon, Nasdaq: TERN), GADLine, a cable telephony systems vendor (sold to Com21, Nasdaq: CMTO) and JOLT/Optical Access Inc., a freespace optical wireless systems vendor (sold to MRV Communications, Nasdaq: MRVC).

Of particular note, Mr. Rauner successfully structured and negotiated transaction terms and related hedging strategies that protected selling shareholders during the volatile market conditions prevailing in 2000-2001.

More recently, Mr. Rauner worked with clients to identify and benefit from opportunities arising from the technology recession. These included advising on an $18 million A round venture capital financing for a company whose technologies lower costs and extend the capacity of legacy wireless networks, as well as a management buyout and subsequent restructuring (including asset sales) of the Israeli operations of a US cable equipment vendor.

Mr. Rauner currently serves as a Director of Popular Telephony, Inc., a provider of middleware for VoIP semiconductors and enterprise communications systems, and on the Advisory Board of CableMatrix, a developer of Quality of Service solutions enabling delivery of multimedia and P2P applications over cable data networks.

A dual citizen of the United States and Israel, Mr. Rauner served as a Captain in the Israel Defense Forces and is a member of the New York and Israel Bar.
