David is Founder, Chairman and CEO of Weild & Co. The studies that he co-authored have documented the long-term decline in equity capital formation in the United States and provided the core arguments that gave rise to the JOBS Act and many of the specific provisions contained in the JOBS Act. For these reasons, he has been called “The father of the JOBS Act.” David has also called for a “JOBS Act 2” or “JOBS Act Part 2” - language increasingly heard on Capitol Hill. The work has been cited by a broad range of legislators, regulators, academics, the IPO Task Force and the White House Jobs Council leading up to the JOBS Act. David has testified in Congress (most recently in June 2013) and at the SEC (most recently at the Roundtable on Decimalization) on these and other market issues and attended the signing of the JOBS Act by President Obama in the Rose Garden on April 5, 2012.
David was also recently asked to author a study for the Organization of Economic Cooperation and Development (OECD) which was entitled, “Making Stock Markets Work to Support Economic Growth” and presented in April 2013 in draft form to the 35 member nations of the OECD, IOSCO and the European Commission. The U.S. Treasury and SEC were in attendance. He later presented the final version at a meeting in June that included the CEO of the World Federation of Exchanges where it was generally agreed, as Weild and Kim have maintained, that structural changes to stock markets have caused the global decline in capital formation for small companies.
David is a former Vice Chairman and executive committee member of The NASDAQ Stock Market and spent years running Wall Street investment banking and equity capital markets businesses.
David holds an MBA from the Stern School of Business and a BA from Wesleyan University. He studied on exchange at The Sorbonne, Ecole des Haute Etudes Commerciales and The Stockholm School of Economics. He is also Chairman of the Board of Tuesday’s Children, the 9/11 charity.
David holds FINRA Series 7, 24, 63, 79, 82 and 99 licenses.
