Company profile
researched Aug 2026C3.ai, Inc. (stylized C3 AI) is an American enterprise artificial intelligence application software company headquartered in Redwood City, California, and listed on the New York Stock Exchange under the ticker AI. Its software comprises the C3 Agentic AI Platform, an ontology-based, end-to-end application development and runtime environment for designing, developing, deploying and governing enterprise AI applications; C3 AI Studio, an integrated development environment used by engineers, data scientists and business analysts; C3 AI Applications, a portfolio of prebuilt industry-specific applications; C3 Generative AI, a library of agentic applications that retrieve data, analyze information, surface insights and orchestrate workflows with cited answers grounded in customer data; and C3 Code, which generates production-grade enterprise AI applications — including data pipelines, models, business logic, security controls and user interfaces — from natural language.
The company markets purpose-built application suites by sector, including defense and intelligence (readiness, decision advantage, intelligence analysis), maritime (production schedule optimization, supply chain orchestration), manufacturing (demand planning, reliability, process optimization), federal, state and local government, oil and gas, utilities (energy management, field services) and healthcare. Reported customers include Dow, which monitors more than 50 steam cracker furnaces with over 13,000 sensors streaming live data and more than 500 AI models in production, and Holcim, which has deployed AI across 85+ cement plants with more than 3,100 models in production and 1,100+ critical assets under predictive maintenance.
For fiscal 2025 (year ended April 30, 2025) the company reported revenue of $389.1 million and a net loss of $288.7 million, with total assets of $1.03 billion and total equity of $838.3 million, and 1,181 employees as of April 30, 2025. More recent market data show trailing twelve-month revenue of approximately $250.3 million and a market capitalization of roughly $1.6 billion.
Founding story
The company was founded in 2009 by Thomas Siebel, previously founder and CEO of Siebel Systems from 1993 to 2006, under the name "C3." The "C" originally referred to carbon and the "3" to "measure, mitigate and monetize," reflecting an initial focus on helping corporations manage their carbon footprints.
Business model
C3.ai licenses enterprise AI software — a platform, development environment and prebuilt industry applications — to large organizations, and also licenses the platform to systems integrators through its Strategic Integrator Program, under which integrators build and resell their own enterprise AI applications with full IP rights.
Revenue is generated from software licensing and related enterprise AI applications and platform usage; reported revenue was $389.1 million in fiscal 2025 (fiscal year ends April 30) and approximately $250.3 million on a trailing twelve-month basis in the most recent market data.
Traction
Customer deployments cited by the company include Dow (50+ steam cracker furnaces monitored, 13,000+ sensors streaming live data, 500+ AI models in production) and Holcim (3,100+ AI models in production, 85+ cement plants with AI deployed, 1,100+ critical assets under predictive maintenance). Fiscal 2025 revenue was $389.1 million against a net loss of $288.7 million; trailing twelve-month revenue in recent market data was about $250.3 million with a net margin of -187.95%. The U.S. Department of Agriculture was reported to have selected C3 AI in connection with reducing its Salesforce usage.
Latest developments
Stephen Ehikian was appointed CEO effective September 1, 2025, with Siebel as executive chairman; company materials later list Siebel as Chairman and CEO beginning in 2026 and Ehikian as President. In February 2026 the company announced a 26% workforce reduction alongside a large quarterly loss, and in August 2026 it appointed John Dwyer to its board of directors and was scheduled to report fiscal first quarter 2027 results on September 2, 2026. It was also named a Leader in The Forrester Wave: AI Platforms, Q3 2026.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
C3.ai positions itself as an enterprise AI platform vendor and was named a Leader in The Forrester Wave: AI Platforms, Q3 2026, following earlier Forrester Wave Leader recognitions for AI/ML platforms in 2022 and 2024. As a public company its market capitalization was approximately $1.6 billion in August 2026, with the share price down materially from its post-IPO highs.
The company emphasizes prebuilt, industry-specific applications built on an ontology-powered platform and grounded in domain expertise accumulated over more than 15 years, combined with generative and agentic capabilities that produce cited answers from proprietary enterprise data and automatically generate governed production applications.
Technology
The core technology is the C3 Agentic AI Platform, an ontology-powered application development and runtime environment for building, deploying and governing enterprise AI at scale, complemented by C3 AI Studio (an integrated development environment), prebuilt AI applications, C3 Generative AI (enterprise generative AI grounded in proprietary customer data returning cited answers), and C3 Code, which uses autonomous agents to turn natural-language requests into production-ready applications with data pipelines, models, business logic, security controls and interfaces. Founder Thomas Siebel is named as inventor or co-inventor on 29 issued patents covering enterprise software architecture, AI systems, large-scale data management and distributed computing.
Go-to-market
The company sells directly to large enterprise and public-sector accounts and works through strategic partnerships with hyperscalers and large systems integrators — including Microsoft, AWS, Google Cloud, McKinsey & Company and Baker Hughes — plus a Strategic Integrator Program that lets partners license the platform to build and resell their own applications. It publishes customer stories and industry-specific application portfolios, and has built a federal business led by a dedicated Federal Systems organization.
Large enterprises and government organizations, including defense and intelligence agencies, navies and maritime shipyards, federal, state and local government agencies, manufacturers, oil and gas operators, utilities, and healthcare organizations.
Geography
Headquartered in Redwood City, California, with operations across North America, Europe, the Middle East, Africa, the Asia Pacific region and internationally.
History
Founded in 2009 and incorporated in Delaware, the company was briefly named C3 Energy and then C3IoT (C3 IoT, Inc.) before changing its name to C3.ai, Inc. in June 2019. Ahead of its public listing it executed a 6-for-1 reverse stock split on November 25, 2020, and went public on the NYSE on December 9, 2020, pricing 15.5 million shares at $42.00 for approximately $651 million in gross proceeds, alongside concurrent private placements of $100 million by Spring Creek Capital (affiliated with Koch Industries) and $50 million by Microsoft. Shares more than doubled on the first trading day to close at $92.49 for a market capitalization of $8.9 billion and reached an all-time high close of $177.47 on December 22, 2020, before declining substantially in subsequent years. Stephen Ehikian, former acting administrator of the U.S. General Services Administration, was appointed CEO effective September 1, 2025, with Siebel becoming executive chairman; company leadership materials subsequently list Siebel as Chairman and CEO from 2026 and Ehikian as President. In February 2026 the company cut 26% of its workforce and reported a large loss.
Risks & controversies
Following the 2020 IPO the company faced market skepticism and criticism, including over Thomas Siebel liquidating shares worth hundreds of millions of dollars in the months afterward, and an investor lawsuit and short sellers questioning its metrics. The company remains substantially unprofitable, with a fiscal 2025 net loss of $288.7 million and a trailing twelve-month net margin of -187.95%, and it cut 26% of its workforce in February 2026 amid declining revenue, with shares falling 17% on that news and trading roughly 79% below their level five years earlier. Voting control is concentrated: as of April 30, 2025, Siebel and related entities controlled approximately 52.4% of voting power through a dual-class structure in which Class B shares carry 50 votes each.
