Addison

What Addison does

Addison, doing business as Sia/Addison, is a New York-based creative agency founded in 1962 that operates as the marketing and creative arm of Sia Partners, a global management consulting firm. The firm delivers four integrated service lines: Branding and Communications (visual identity, messaging, brand guidelines, employee engagement), Annual Reports and Proxies (investor communications, integrated reporting), Sustainability Strategy and Communications (materiality analysis, ESG reporting under GRI/SASB frameworks, rating and ranking surveys), and Digital Experiences (website design, video, mobile, CMS integration). Addison is supported by SiaGPT, a proprietary AI toolset that accelerates sustainability benchmarking, gap analyses, disclosure drafting, and document search within its ESG practice.

The firm's client base is concentrated in Fortune 500 enterprises across banking, asset management, pharmaceuticals, technology, consumer goods, and defense. Named engagements span BlackRock, Bank of America, IBM, GE, Merck, Amazon, Meta, AT&T, PepsiCo, Sonos, ADCB, and others, with multi-year relationships documented (e.g., Merck's sustainability reporting for 11+ years). The agency has been recognized through exhibition of its work at the Cooper Hewitt Design Museum and inclusion in the Smithsonian National Air and Space Museum's permanent collection, and its 1987 goldfish brand symbol remains a registered identity asset.

Addison generates revenue through professional services engagements priced on a quote-based, project-by-project basis with no public pricing or subscription model. The go-to-market is direct enterprise sales, primarily initiated through website contact forms, email inquiries to [email protected], and LinkedIn outreach, with client relationships cultivated over multi-year cycles. The company is privately held as a subsidiary of Sia Partners, headquartered at 48 Wall Street in the Bank of New York skyscraper (office designed by Gensler), with a headcount of 51-100 and a North America-domiciled operating footprint.
