Brenon oversees the financial analysis of The 451 Group's TechDealmaker and KnowledgeBase products, having covered more than a quarter-trillion dollars' worth of deal flow for both national publications and research firms.

Brenon began his career in 1991 as one of the initial reporters at Prognosis, the first English-language newspaper in the former Eastern Bloc. While there, he covered the Czech Republic's transition to a market economy, as well as larger financial stories across the region. Expanding on that, Brenon moved to Vienna in 1995 to run the local bureau for United Press International. In addition to reporting extensively on Austrian politics and economics, he also coordinated and edited EuroBusiness stories from correspondents in Slovakia and Hungary. After UPI, Brenon moved to an analyst position with the Economist Group, where he researched and wrote reports for The Economist Intelligence Unit and the regional publication of The Economist.

Returning to the US in 1997, Brenon helped establish the editorial voice in the early days of CBS MarketWatch, the most popular online financial news site. During his time there, he helped launch OptionsWatch, covering options trading, and MarketPulse, a minute-by-minute report on stock activity licensed primarily to brokerages. Since 2000, Brenon has focused his reporting on M&A as a reporter for The Deal. During that time, he also sharpened his analytical skills, writing reports for TechDealmaker (since acquired by The 451 Group) and the boutique research firm Intellectual Capital Associates.
