Gelb Information Systems

What Gelb Information Systems does

Gelb Information Systems Corporation (GIS) is a privately held, founder-owned IT consulting firm founded in 1983 and headquartered in Marlboro, New Jersey. The firm specializes in management and technical consulting across systems management, performance management, capacity planning, and applications development, with historical depth in mainframe, client-server, and distributed systems environments. Its three named practitioners — President Ivan Gelb (30+ years experience, formerly of Morgan Guaranty Trust and Chase Manhattan), Dr. Bernie Domanski (A. A. Michelson Lifetime Achievement Award recipient, tenured CUNY professor, ~100 publications), and Lyn Hecker (20+ years experience, CMG Philadelphia officer) — are the firm's principal asset and the focal point of its go-to-market.

The business model is professional services: revenue is generated through billable consulting engagements plus a seminar and training business. Since 1983, the firm reports assisting 150+ consulting clients and training representatives from 500+ companies. Named customers include JP Morgan, Merrill Lynch, Fidelity, State Street Bank, PepsiCo, Coca-Cola Enterprises, FBI, State of California, US Department of Veterans Affairs, and international accounts spanning Denmark, Thailand, South Africa, England, and Italy. A proprietary repository of IT systems characteristics provides a benchmarking asset for client comparisons, and the firm historically developed an expert systems-based performance modeling package — an early-application methodology rather than a current commercial product. Pricing is custom-quoted by project scope; no platform, subscription, or productized offering is disclosed.

The firm has no subsidiaries, no external funding, no disclosed M&A activity, no public social presence beyond its gelbis.com domain, and a website last modified December 2002. Marketing relies on the Computer Measurement Group community, conference speaking, peer-reviewed publications, and seminar-driven referrals. Operating geographies span the United States with historical international engagements, but there are no recent signals of geographic or product expansion.
