Warren Lazarow, Firmwide Co-Chairman of O’Melveny’s Corporate Department, is nationally and internationally recognized as one of the market’s leading advisors to technology-focused companies and investors. Warren primarily focuses his practice on the corporate representation of public and private technology companies, venture capital and private equity firms, and investment banks. He is a boardroom-level advisor who frequently serves as outside general counsel, helping management teams, boards of directors, and investors shape and execute their business strategies, and providing experienced counsel on legal issues ranging from day-to-day corporate and regulatory matters to high-stakes strategic matters. Over the course of his career, Warren has handled more than 200 M&A transactions ranging from US$1 million to US$10 billion; more than 100 public offerings of equity, debt, and convertible securities, raising more than US$2.6 billion; and more than 1,000 private financings spanning initial seed financings, venture capital financings, growth capital financings, private equity financings, and recapitalizations.

Warren has been chosen four times for inclusion on Forbes Magazine’s prestigious “Midas List” of the technology industry’s Top 100 Dealmakers Worldwide. Law firm rankings publications, including Chambers & Partners (USA and Global guides), Legal 500, Global Counsel, IFLR, and Practical Law Company, have awarded him high rankings in listings of top lawyers for “Corporate/M&A,” “Capital Markets,” “Communications/Technology,” “Venture Capital and Emerging Companies,” and “Private Equity - Buyouts: $10 billion and above.” Legal 500, in its “Venture Capital and Emerging Companies” section, describes Warren as “highly recommended by clients in the [technology] space for his ‘truly significant experience’” and the “key person in the [industry] for all manner of corporate legal issues.” Chambers and Partners notes that Warren is “praised for his practical and intelligent advice” and that he is “particularly known for his representation of technology companies in the emerging companies space.” Numerous business and legal media outlets, including PE Hub Wire, FeedBlitz, The Deal, TechCrunch, The Daily Deal, Private Equity Law 360, Term Sheet, The Recorder, The New York Times, The Wall Street Journal, BusinessWeek, Silicon Valley Business Journal, MSNBC, VentureBeat and CNN, have quoted Warren or covered transactions on which he has worked. He has spoken on issues impacting technology companies before audiences throughout the US, Japan, China, Singapore, Indonesia, Korea, Taiwan, Israel, and Europe.
