What Antenna Group does

Antenna Group is a global marketing and communications agency that serves enterprise "conscious brands" operating at the intersection of climate, energy, sustainability, health, mobility, real estate, and industrial innovation. Founded in 1996 and privately held, the firm is domiciled in New York and operates from five offices spanning the US (New York, Hackensack, Washington D.C.), the UK (London), and Central Europe (Prague). Its named client roster includes enterprise accounts such as Kairos Power, ABB, Enphase, Sunrun, Anew Climate, Echogen, Common Charge, Epic Cleantec, Somerset, and Branch, indicating engagement at the enterprise tier within climate- and sustainability-adjacent verticals.

The agency's service portfolio is an integrated stack spanning strategy, storytelling, media relations, earned and paid media, content production, brand identity, creative, executive positioning, thought leadership, public affairs, experiential marketing, and performance/digital marketing. Branded assets include the "Age of Adoption" podcast (98+ episodes featuring climate tech builders, backers, and policymakers) and the "Conscious Compass Assessment," a self-evaluation tool that scores organizations across eight traits of brand consciousness. The firm operates as a professional services company with no proprietary software platform, API, or SDK; its underlying "technology" consists primarily of standard agency tools and content production workflows.

Antenna generates revenue through project-based and retainer professional services engagements sold directly to enterprise clients via website inbound ("Let's Chat" CTA), conference networking (e.g., Page Society), and referral channels. Pricing is quote-based and not publicly disclosed. The company has no disclosed funding rounds, no institutional ownership, and no public revenue figures. Strategic activity in the past 18 months has centered on European expansion via the September 2024 acquisition of Czech PR firm Rubikon PR and the 2024 opening of a London office, together with a May 2025 minority investment in creator-economy technology company No Logo, signaling both geographic build-out and ecosystem extension.

Direct peers

• Hotwire: B2B technology and communications agency with a sustainability practice serving enterprise tech and clean-energy clients. Most directly comparable in terms of integrated B2B storytelling for technology-forward enterprise brands.
• Ruder Finn: Independent global communications agency with a longstanding sustainability and health practice. Comparable in serving enterprise clients across sustainability, health, and transformation storytelling with similar integrated agency capabilities.
• Purpose: Strategy and communications agency that builds and runs movements for progressive brands and climate causes. Comparable in mission alignment with 'conscious brands' and sustainability transformation work, but skews toward advocacy and campaigns rather than enterprise B2B.
• Walker Sands: B2B integrated marketing and PR agency serving technology, sustainability, and clean-energy clients. Comparable as a mid-sized agency providing PR, creative, and performance marketing to enterprise tech-forward brands, though more US-centric.
• Salterbaxter (MSL): Sustainability communications consultancy, now part of MSL/Publicis Group. Direct comparable to Antenna's climate and sustainability storytelling offering, with the additional scale benefits of Publicis Group ownership.
• Futerra: Communications and strategy agency exclusively focused on sustainability and climate brands. Most direct comparable to Antenna's 'conscious brands' positioning, though typically serves more consumer-facing and nonprofit clients versus Antenna's enterprise cleantech focus.

Broad incumbents

• Weber Shandwick: Global integrated communications agency with a Sustainability and Purpose practice. Competes with Antenna for the same enterprise conscious-brand and transformation storytelling mandates, but offers significantly broader global infrastructure.
• Edelman: World's largest independent PR firm with a dedicated sustainability and climate practice. Comparable as a B2B communications agency serving enterprise climate and transformation clients, but operates at vastly greater scale and breadth than Antenna.
• FleishmanHillard: Large Omnicom-owned PR and integrated communications agency with a sustainability practice. Direct competitor for climate and clean-tech enterprise communications work, though Fleishman serves a far broader cross-section of industries.
• APCO Worldwide: Global advisory and communications consultancy with strong energy, sustainability, and climate practice. Comparable in serving enterprise climate-tech and clean-energy clients, but offers broader public affairs and government relations capabilities.
