About The IAOP Global 100
In 2026, IAOP is celebrating 20 years of the annual ranking. This year, The Global Outsourcing 100 evolved into The IAOP Global 100, reflecting the full sourcing and business services ecosystem.
The Global 100 and its sub-lists serve as key resources for companies exploring new partnerships or expanding existing ones with top outsourcing providers. These rankings feature firms that offer a full range of services around the world, from IT and business process support to facility operations, real estate, capital asset management, manufacturing, and logistics. The lists highlight not only current industry leaders but also emerging companies that gain momentum.
Companies of any size and from any region – IT, business process outsourcing, facility management, real estate, design, testing, manufacturing, and logistics – are eligible to apply for inclusion on these lists. IAOP membership is not required and does not influence the selection process.
The IAOP Global 100 includes the following categories:
- Leaders, well-established global firms
- Rising Stars, smaller companies with under $50 million in annual revenue or fewer than 5,000 employees
- Advisors, consulting organizations of any size
Companies are first grouped under Leader, Rising Star, or Advisor categories. Each is then assessed across four judging criteria. The final list includes those with the highest overall scores, regardless of category.
In 2026, the judges examined and evaluated the following sub-categories:
- Customer References, as demonstrated by the value generated at the company’s most valuable clients
- Awards & Certifications, as proven by the value generated through industry recognition and pertinent professional certifications earned by individuals and organizations
- Programs for Innovation, as evidenced by particular initiatives and their outcomes, which create new kinds of value for clients
- Programs for Social Impact, as shown by business initiatives and results that tackle issues like consumer concerns, labor practices, human rights, fair business practices, environmental effects, community development, and organizational governance
The scoring process follows a strict methodology, with final evaluations conducted by a panel of IAOP customer members who have significant experience selecting outsourcing providers and advisors for their companies.
The combined scores across the evaluated areas determine which companies appear on the list. Every company named has demonstrated excellence on a global scale. A full “star” is awarded to any company that stood out in at least one judging category.
