Who We Are

GLG is driven by the curiosity of approximately 1,000 employees around the world who are transforming the way the top professionals share expertise and learn.

Soon after its founding in 1998 GLG began connecting top professionals across fields and around the country. Over time, we became a membership of leading experts providing business decision-makers with insights to create better, more informed outcomes.

Today, we are the world’s largest membership network for one-on-one professional learning, comprising more than 400,000 thought leaders and practitioners, including business leaders, scientists, academics, former public sector leaders and the foremost subject matter specialists. We serve users at more than 1,400 client companies in 40 countries. These clients include Fortune 500 companies in nearly every sector and the leading professional services firms and financial institutions.

GLG’s industry-leading compliance framework allows clients to learn in a structured, auditable, and transparent way, consistent with their own internal compliance obligations and the highest professional ethical standards. Our compliance standards are a major competitive differentiator and key component of the company’s culture.

GLG is headquartered in New York with 22 offices globally and 1,000 employees.
