Executive Management Team
Harpal Sandhu
President & Chief Executive Officer

Simultaneously, Harpal set out to expand Integral's executive management team and to prepare the company for rapid growth. Prior to founding Integral in 1993 with Viral Tolat, Harpal was founder and president of Infinity Financial Technology, a leading supplier of software products for the financial services industry, which was acquired by SunGuard Data Systems in 1998. Harpal began his career as a financial engineer in the Capital Markets Product Development Group at Morgan Stanley & Company. Working at its New York and London offices, he helped model many of the early derivative financial instruments. Harpal holds a BA from Stanford University. He is also a frequent speaker at industry events and conferences.
