Editor's Note (2026 Update)
The 2013 framing in earlier versions of this piece described an Antenna / Beckerman "merger." The accurate sequence: Beckerman acquired the original San Francisco-based clean-tech PR firm The Antenna Group in 2010 as a sector specialty within the Beckerman holding company. In April 2019 — celebrating Beckerman's 30th anniversary — the parent firm consolidated all subsidiaries (Beckerman, Eco Branding, Chicago Digital) under the unified Antenna Group brand. The agency operates under that name today.
Antenna Group is now a global marketing and communications agency with approximately 150 employees across New York, San Francisco, Chicago, Detroit, Washington D.C., and London (Covent Garden, opened 2024–2025 as the firm's first transatlantic office). Annual revenue runs $28.9M–$35M. Keith Zakheim remains CEO. Sector focus: climate & energy, mobility, real estate & PropTech, healthcare, B2B tech, public affairs, and venture capital.
