Bill Seibel was born and raised in a small coal mining town southwest of Pittsburgh. From the time that he turned twelve, he knew that he wanted to be an entrepreneur—even though he wasn’t entirely clear on what entrepreneurship was, how to accomplish it, or how to pronounce it correctly. It took Bill twenty-five more years to join his first startup, getting a degree in engineering from Penn State, an MBA from Carnegie-Mellon, and working twelve years for Air Products, a Fortune 100 company, along the way.
At Air Products, Bill held a number of executive positions, including Director Materials Management and Director Information Technology. But he longed for a chance to impact business more than he believed he could at a Fortune 100 industrial gas and chemical company. He hoped he would find that opportunity in the world of startups, and left to join McCormack & Dodge (M&D) as general manager of one of the enterprise software company’s businesses. In less than a year, he was running engineering worldwide.

Next Bill joined Index Technology as Executive Vice President Operations. The software tools startup reached revenue of $44 million and merged with Sage Software to create a business with 100,000 users in 10,000 accounts across the world. Soon after the merger, Bill joined Cambridge Technology Partners (CTP) as a member of the founding team. CTP became a public company and was named the #2 IPO of 1993. After successfully building their international operations, he returned to the US as Executive Vice President Operations. When he departed seven years later, the company had grown to over $800 million in revenue, with 4,000 employees in fifty offices and a $5 billion market cap.

After CTP, Bill raised $100 million to launch ZEFER. As Chairman and CEO, he grew revenue to $136 million in the startup’s first eighteen months in business—setting the record as the fastest growing professional services firm ever. ZEFER’s growth led to Red Herring awarding it Top Company to Watch and its delivery track record resulted in Gartner naming it Magic Quadrant Leader.
Next he joined Demantra as Chairman and CEO, and restarted it as the leading predictive analytics software company. That led to being named Best Business Turnaround, and a successful acquisition by Oracle soon afterwards.

Bill followed that by launching Gumball, a consulting firm that worked with more than thirty startups to help them scale their businesses. After that, he was Chairman and CEO of a security and network performance software startups —leading both to successful exits.

Next Bill founded Mobiquity. Under his leadership, the startup was named the Fastest Growing Company in New England, one of the Top Mobile Firms in the World (Forrester), One of the Five Coolest Tech Vendors on the Planet (Gartner), and a finalist for MassTLC Company of the Year. Mobiquity was recently acquired by Hexaware for $182 million.
