Thunder11 is a senior-led C-level communications boutique operating at the intersection of technology, healthcare, and public affairs. Founded in New York City in 2007 by Marco Greenberg, the firm has spent nearly two decades positioning itself as a deliberately small, executive-counsel-led shop serving Fortune 500 corporations, venture-backed and angel-backed startups, foreign governments, democratic movements, and NGOs. The firm operates from 12 West 90th Street in Manhattan with approximately 12 employees and roughly $6 million in annual revenue. The name is drawn from Marshall McLuhan's theory of ten thunderous moments in human history — Thunder11 positioning itself at the eleventh, unfolding now online.
The Founder and the Founding Era
Marco Greenberg founded Thunder11 in 2007 in New York City after serving as a Managing Director at Burson-Marsteller, where he counseled multinational corporations and government clients across reputation and crisis assignments. The founding thesis was that a deliberately small, senior-led boutique could outperform large-network practices for clients who needed direct executive engagement on positioning and messaging — not handed to junior staff. The thesis held. Greenberg has written for Business Insider, Entrepreneur, the New York Daily News, Tablet Magazine, and Thrive Global across the firm's operating history.
Service Offering
The firm delivers four integrated capabilities: positioning and messaging, content, public relations, and events and research. The capability stack is intentionally narrow. The firm does not run paid media, large-scale influencer programs, or social-first creative — services that would scale the headcount and dilute the senior-led model.
The Roster
Thunder11's client base spans Fortune 500 corporations, healthcare organizations, venture-backed and angel-backed technology startups, foreign governments, democratic movements, and non-governmental organizations. The firm's sector mix — technology, healthcare, and public affairs at the same time — is unusual at boutique scale and reflects the founder's policy and corporate background.
