Best AI Development Companies in 2026

Accenture plc, incorporated in Ireland with principal executive offices in Dublin, reported revenue of US$74.2 billion for the fiscal year ended 31 August 2026 and employed about 814,000 people. Its 2026 annual report names AI and Data as one of three internal "Reinvention Engines", responsible for building AI skills, incubating frontier AI partnerships and developing AI platforms that clients use to scale their AI investments. The company states that a US$3.0 billion, three-year AI investment positioned it to capture client spending on AI, and that it expects to invest at least US$1.0 billion over five years in AI safety. Revenue comes mainly from Forbes Global 2000 companies and government agencies.

International Business Machines, headquartered in Armonk, New York, reported total revenue of US$67.5 billion for 2025. Unlike the other companies in this list, IBM sells AI software and infrastructure as well as services: its annual report describes hybrid cloud and AI platforms that let clients carry out AI transformations across their applications and data, and a Consulting segment that combines strategy, experience design, technology and operations expertise to deliver transformation programmes. IBM states that it competes with hundreds of companies worldwide as it pursues its hybrid cloud and AI strategy. The total revenue figure includes software and infrastructure sales, so it overstates the size of the services business relative to pure-play consultancies.

Cognizant Technology Solutions, headquartered in Teaneck, New Jersey, reported 2025 revenue of US$21.1 billion and ended the year with about 351,600 employees, up from 336,800 a year earlier. Its 2025 annual report describes the company as an "AI builder" that combines industry knowledge with knowledge of clients' organisations to build industry-specific platforms and to embed context into systems, AI models and custom solutions. It helps clients implement and operate AI with integration, governance, security and monitoring controls, using intellectual property developed in its AI Lab. Cognizant also builds and runs global capability centres for clients.

Infosys Limited, with principal executive offices in Bengaluru, India, reported revenue of US$20.2 billion for the fiscal year ended 31 March 2026, up from US$19.3 billion a year earlier. It had 328,594 employees at that date, of whom 310,887 worked in service delivery. Its AI offering is built around Infosys Topaz, which the company describes as its generative and agentic AI suite, and an "AI first" value framework intended to help enterprises deploy AI at scale. The 20-F cites market estimates of a US$300–400 billion AI services opportunity by 2030.

Booz Allen Hamilton, headquartered in McLean, Virginia, reported revenue of US$11.2 billion for the fiscal year ended 31 March 2026, down from US$12.0 billion the previous year, and employed about 31,500 people. Its annual report describes it as the federal government's largest AI provider, with about 400 active AI projects, building secure AI systems including agentic AI, physical AI and AI for radio access networks for mission-critical environments. Most of its work is for US defence, intelligence and civilian agencies. The company plans to move its headquarters to Reston, Virginia, in autumn 2027.

EPAM Systems, headquartered in Newtown, Pennsylvania, traces its origins to a predecessor founded in 1993. It reported 2025 revenue of US$5.46 billion and had about 62,850 employees at year end, of whom about 56,600 were delivery professionals. The annual report states that its strategy is increasingly focused on end-to-end "AI-native" transformations and describes the ability to move clients from AI experimentation to production as a differentiator. EPAM expanded in Latin America and Spain through the acquisition of NEORIS, a consultancy with about 4,800 professionals, and continued to grow its delivery base in India.

Genpact reported 2025 revenue of US$5.08 billion and had more than 146,500 employees working in over 35 countries. Its annual report describes it as "an agentic and advanced technology solutions company" built on industry knowledge and process intelligence. Genpact argues that its experience running clients' business processes, such as finance and accounting, gives it the operational detail needed to deliver AI and agentic solutions for the "last mile" of execution, where general-purpose AI tools often stall.

Globant S.A., incorporated in Luxembourg, was founded in 2003 by Martín Migoya, Guibert Englebienne, Martín Umaran and Néstor Nocetti. It reported 2025 revenue of US$2.45 billion and had 28,773 employees in 31 countries at year end. In 2025 it introduced AI Pods powered by its Globant Enterprise AI platform, giving clients access to agentic AI capabilities, and a subscription-based pricing model for AI-powered engineering, product definition, design and testing services. It also opened a Middle East regional headquarters in Riyadh.

ExlService Holdings (EXL), founded in 1999 and headquartered in New York, reported 2025 revenue of US$2.09 billion and has more than 65,000 employees. The company describes its aim as being an indispensable partner for data- and AI-led transformation, and in early 2025 restructured its reporting so that data and AI-led services form one of its two main service lines alongside digital operations. Its clients are concentrated in insurance, healthcare and life sciences, banking and capital markets, and retail.

Grid Dynamics, founded in 2006 and headquartered in San Ramon, California, reported 2025 revenue of US$412 million and had 4,961 personnel across the Americas, Europe and India. Its annual report presents the Grid Dynamics AI-Native (GAIN) engagement model as its strategic foundation, a framework that changes team composition and engineering workflows for software delivery with AI. The company argues that agentic AI systems need distributed, fault-tolerant engineering to run reliably at scale, which it presents as its core skill. Its engineers held more than 1,600 cloud hyperscaler certifications at year end.

Innodata, founded in 1988 and headquartered in Ridgefield Park, New Jersey, reported 2025 revenue of US$251.7 million, up from US$170.5 million in 2024, and employed 10,107 people at year end. Rather than building business applications, it supplies AI lifecycle data services: training and post-training data, alignment and preference optimisation, and capability and safety evaluation. Its 10-K states that its customers include leading AI labs and five of the so-called "Magnificent Seven" technology companies, and that a substantial share of revenue comes from the largest technology companies.

BigBear.ai Holdings, with principal executive offices in McLean, Virginia, reported 2025 revenue of US$127.7 million, down from US$158.2 million in 2024, and had 579 employees, most of them in the United States holding security clearances. It develops AI systems for national security, travel and trade, including identity verification and biometrics. On 31 December 2025 it completed the acquisition of Ask Sage, a generative AI platform for defence and intelligence customers that the company describes as the first of its kind to receive FedRAMP authorisation.
