A man in a suit and tie sitting down.

Mark Landesmann was born in Vienna and lives in Palo Alto, California. He currently writes narrative nonfiction, studies creative writing at Stanford Continuing Studies, and manages a private investment portfolio.

Over an earlier career in technology, he developed and licensed solutions to communication problems in collaboration with corporate partners. The United States Patent Office granted him eight umbrella patents, which have since been widely cited as prior art, including by Visa (in 147 patents), JPMorgan Chase (30), Cisco Systems (27), and Amazon (16).

Before founding BuyerLeverage, he was Vice President for Email Marketing and Major Accounts at Cybergold. He built and led the team that grew permission email marketing from 3 percent to 80 percent of company revenues, and helped take Cybergold public. Earlier, he founded Landesmann International Marketing, a market-leading food-trading and asset-financing company operating in New York, Vienna, and across Eastern Europe and Latin America.

He was a leading advocate for socially responsible investing on Stanford University's Investment Policy Committee and served as Amicus Curiae to the United States Supreme Court in a precedential patent case, for which he authored an Amicus Brief.

He holds a B.A. in Economics and an M.A. in International Policy Studies from Stanford, and an MBA from the Harvard Business School, earned on a full scholarship.
