APCO Worldwide

One of the largest independent global public affairs and communications consultancies, known for government relations, corporate reputation, and integrated advocacy campaigns

APCO Worldwide is an independent, majority employee-owned global advisory and advocacy communications consultancy founded in 1984 by Margery Kraus. Headquartered in Washington, D.C., the firm operates across more than 30 offices worldwide and provides integrated services spanning public affairs, corporate communications, crisis management, stakeholder engagement, and digital strategy. APCO works with multinational corporations, trade associations, NGOs, and governments to shape narratives, influence policy, and manage reputational risk in complex regulatory and political environments. While not a traditional AdTech company, APCO occupies a significant space at the intersection of communications, advocacy, and paid media strategy. The firm advises clients on integrated campaigns that blend earned, owned, and paid media — including digital advertising, social media strategy, and targeted stakeholder communications — making it relevant to the broader marketing and communications technology ecosystem. Its global reach and deep government relations expertise differentiate it from pure-play PR or advertising agencies. APCO is consistently ranked among the top independent global communications consultancies and has been recognized for its work in corporate reputation, ESG communications, and public affairs. The firm's independence from large holding companies is a key selling point, allowing it to offer conflict-free counsel across industries including healthcare, energy, technology, financial services, and consumer goods.
