History of GLG

1998

Gerson Lehrman Group is founded in New York City as a publishing company focused on sector-specific reports for investors.

Mark Gerson and Thomas Lehrman, both in their late twenties, raise $1 million to start the company. Alexander SaintAmand joins as an editor during his senior year at college. GLG initially produces reports by engaging industry experts – academics, scientists, and physicians – to write about industries undergoing massive technological or regulatory change.

Mark, Thomas, and Alexander realize they have the opportunity to do much more than produce reports, they can fundamentally change the way companies conduct primary research.

After attending a number of industry conferences on behalf of potential clients, Alexander witnesses the power of informal, one-to-one, and small group conversations that take place between programmed events. GLG begins building the technical infrastructure that allows it to connect client requests with relevant experts, creating a new professional learning platform.
