Marc Weill

Senior Advisor, Two Sigma Ventures

In a career that has spanned more than three decades and nearly every aspect of financial services, Marc Weill has served in key roles at several top firms, including Chief Investment Officer at Citigroup. Weill is currently a Senior Advisor at Two Sigma Ventures where he helps source and evaluate investment opportunities while providing strategic support to their portfolio companies. He is fascinated by the intersection of health and financial wellness and the tech solutions created by dynamic founders. Weill holds an MBA in Finance and Accounting from Columbia University and a BA in Economics and Business from Vanderbilt.  

Weill began his career interning under future Fed Chairman Dr. Alan Greenspan while getting his dual undergraduate degrees in 1978. Upon graduating with his MBA in 1980, Weill went to work under Dwight Faulkner in the management training program of Shearson Lehman Brothers, a unit of American Express. In 1982, Weill moved to S.B. Lewis as a Risk Arb. trader but returned to Shearson in 1983 to join the Asset Management Group where he quickly established himself as an adept financial advisor, overseeing 500 retail and institutional clients, earning Chairman’s Club status with his exceptional performance. In 1989 he departed Shearson to join Smith Barney as Vice President of the firm’s Restructuring Group. In 1992 he became Chief Investment Officer and Executive Vice President of Primerica, managing $2 billion dollars of company assets. 

After the Travelers merger in 1994, Weill was named Chief Investment Officer overseeing $30+ billion dollars in assets. Over the next six years, which included mergers with Solomon Brothers and Citibank, the assets grew to over $130 billion, which generated over $7 billion in revenue, and an expansion of staff from 250 to over 600 employees. In 1997, Weill was promoted to Senior Executive Vice President and named to Travelers/Citigroup’s influential 16-member Management Committee, comprised of the company’s most senior officers. Weill also established a $30-billion Alternative Investment Group that incubated funds including Tishman Speyer Realty Fund, Tribeca Investments, Greenwich Street Capital Partners, Rivkin Venture Capital Fund, a Brazilian infrastructure fund, and an Israeli technology venture capital fund.  

At the beginning of the new millennium, Weill traded in his powerful corporate position at Citigroup Investments for the freedom of entrepreneurship and the flexibility to pursue his own unique interests, both within and outside the financial industry. Simultaneously, Weill co-founded Fine Minerals International, drawing on his extensive knowledge in geology and minerals and mastery of lapidary arts to pursue new mineral discoveries globally. In 2004 he also founded City Light Capital Investment, an impact investing venture capital firm specializing in startup and early-stage enterprises that positively impact society.  

In 2014, Weill joined Two Sigma Ventures, an early-stage venture capital fund investing in transformative companies, harnessing information growth and computing power to change the world. Weill continues to focus on investment opportunities in financial, digital and health technologies and provides strategic support for Two Sigma’s venture capital fund’s portfolio companies.
