About Bob Hornung

Bob Hornung is an entrepreneur, company chief, and business development executive who, over the last twenty-five years, has established and grown several successful ventures. He specializes in creating strategic alliances with industry leaders, developing domestic and international distribution channels, analyzing market dynamics, and identifying new opportunities to maximize sustainable competitive advantages. Bob has also had the good fortune of being able to partner with talented professionals including his brother, James Hornung, Mark Wolonsky, Phil Dewilde, and Joe Horning.


His career began at his family’s business in Connecticut, where he developed an interest for industry and its challenges. This interest eventually led him to enroll in the Whitman School of Management at Syracuse University (formerly the Crouse Hinds School of Management), from which he earned a Bachelor of Sciences degree in Business Marketing.


After graduating, one of Bob’s first moves was to join Industrial Sales Corp (ISC), the largest window industry sales and distribution organization in the United States. For the next few years, he would establish partnerships and pursue various entrepreneurial ventures before developing new fenestration technology in the late 1990’s.


In 1993, Bob founded On-Link, a business application software company that was the first of its kind in any industry. In 1994, he founded Interactive Data Systems (IDS), an electronic catalog technology provider. After much success, On-Link and IDS merged to form On-Link Technologies Inc. in 1998. Since then, On-Link Technologies has grown into a leading e-commerce software company. After successfully raising $36 million, On-Link Technologies was purchased by Siebel Systems Inc. in August of 2000 for over $600 million.


In 1999, Bob Hornung founded Sashlite LLC, an intellectual property firm that streamlined the window manufacturing process. The technology integrated an insulated glass spacer directly into the sash profile that could be incorporated into any size operation. Sashlite partnered with leading companies such as H.B. Fuller Company (NYSE: FUL), Bystronic Glass, Ashland Hardware Systems, and Deceuninck North America (DAX). Sashlite was sold in 2017 in a private transaction.


In 2017, Bob founded EVO Systems LLC, where he currently serves as Founder and President. EVO is the first, end-to-end, distribution solutions provider serving the fenestration industry throughout the United States. EVO is considered to be one of the nation’s fastest growing firms. The company has built an extremely robust ERP, EDI, and other sophisticated advancements to achieve this early success.


Most recently in 2018, as co-founder of ISC Penn Hudson Advisory M&A, the firm originated and closed Harvey Building Products’ acquisition of Northeast Building Products. This was one of the industry’s largest acquisitions in 2018. ISC Penn Hudson M&A is a leading advisory firm in the fenestration industry offering guidance to companies dealing with macro issues and opportunities that impact their businesses.


Outside of the fenestration industry, Bob currently serves as the Managing Director of Vertical Ventures, which specializes in funding and managing early stage companies.
