Who We Are

An agency team greater than the sum of its parts

Crossbow Group is exactly that, a group of talented direct marketing and e-commerce professionals with the expertise to target, reach and convert prospects into long-term customers. We are strategists, managers, problem-solvers and executives—all adding value in his or her own way. We’d like you to meet a few of them.

Bill Mirbach


Visionary. Pioneer. Free spirit. All describe our founder H. William Mirbach. In 1984, Bill founded the company that went on to bear his name for 16 years. Using innovative direct marketing techniques (some of which he created), he built Mirbach into an elite agency specializing in high-tech direct marketing. Then, as President and CEO of, he worked with Larry Ellison of Oracle, the company’s Chairman, to apply his considerable knowledge of direct marketing and the web to the burgeoning application service provider (ASP) marketplace. Bill is a former Procter and Gamble Brand Manager and a graduate of Harvard Business School.

Jay Bower

President and CEO

Jay likes to call himself Crossbow’s “Chief Archer.” That’s fair; he is. He’s led strategic and tactical engagements with over 250 companies, ranging from Fortune 500 multinationals to start-ups. Prior to Crossbow, he served as Vice President and co-founder of the e-business consultancy Prescients, where he helped craft online strategies for PriceWaterhouse Coopers, Gartner Group, Media Metrix, Cendant and Verizon. At Blau/Brann/EuroRSCG, Jay helped IBM develop web-based relationships with its largest corporate clients. Jay has been quoted (and misquoted) in Fortune, Forbes, USA Today, Entrepreneur and Ad Age. He is a published author (an obscure tome about software: Amazon sales rank 2,369,033). He is a graduate of Colgate University, holds an M.B.A. from The Stern School of Business, New York University, and completed the e-B2B Program at Harvard Business School.

Mary Plamieniak

Chief Operating Officer

No idea, regardless of its potential, is any better than its execution. That’s the kind of take-no-prisoners thinking Mary brings to the table as Production Director and Chief Operating Officer. Over the years, Mary has saved our clients hundreds of thousands of dollars, and made sure that the quality of our work meets the most rigorous standards. Her past life includes stints at GDI/The River Group, FPS Marketing Group and Promotion Development Corporation, for companies that include Citicorp, TransWorld Airlines and SNET.
