William F. Weissman, CFO

With over 25 years of experience at the executive level, William (Bill) Weissman is a business veteran who has a distinguished track record of successfully leading early-stage technology companies through periods of rapid international expansion.

Before joining the team at RSVP Ventures, Bill was CEO and a Director at Rubicon Technology, Inc. (RBCN) a NASDAQ listed manufacturer of sapphire products used primarily in the LED lighting supply chain. Bill was the CFO at Rubicon from 2007 until he assumed CEO responsibilities in September of 2014. Bill led Rubicon’s IPO and played a key role in the company’s international expansion during his tenure as CFO. Beginning in 2012, unprecedented events in the sapphire industry resulted in a massive oversupply of production capacity by competitors in China. Bill was asked to assume the CEO role and tasked with salvaging the sapphire business by reducing product cost and introducing new products.

Previously, Bill was CFO of Kanbay International, Inc., a provider of IT services to the financial services industry, from 1995 through Kanbay’s acquisition by Capgemini in 2007. In 1995, Kanbay had 60 associates. At the time of the Capgemini acquisition, Kanbay had over 7,500 associates in fourteen cities across eight nations, including 3 major development Centers in India. Kanbay became one of the top five performing IPO’s on the NASDAQ in 2004, and was ranked #9 on BusinessWeek’s Annual “Hot Growth Companies” List in 2005. In addition to supporting rapid organic growth, Bill played a key role in several successful acquisitions, including that of Adjoined Technologies, a 500-person consulting firm and the acquisition of Kanbay by Capgemini.

Bill started his career in public accounting and held a number of staff and managerial positions at Lockheed Electronics, Airco BOC and TemStar before joining Kanbay.  He is a Certified Public Accountant and holds a BA in Finance from Seton Hall University.
