OpenAI buys Tomoro and raises $4B to staff AI inside companies

OpenAI said on Sunday that it will form a subsidiary called the OpenAI Deployment Company. The new entity aims to place specialized AI engineers inside businesses to help them rethink their operations around OpenAI’s models. 

The new entity has backing of +$4 billion. OpenAI will own and control the majority of the new company.

The ChatGPT maker wants to put Forward Deployed Engineers in charge of the unit. They will work inside businesses to find the best ways to use AI, change workflows, and create production systems that connect OpenAI’s models to the client’s own data and tools.

To get started fast, OpenAI agreed to acquire Tomoro, an applied AI consulting firm formed in 2023 in partnership with OpenAI. Tomoro’s client list includes Tesco, Virgin Atlantic, Mattel, Red Bull, and Supercell.

Once the deal is approved by the regulators, it will bring ~150 engineers and deployment experts to the subsidiary.

OpenAI partners with 19 investment firms

OpenAI and 19 other investment firms, consulting firms, and system integrators work together to form the deployment company. TPG leads the group. Advent, Bain Capital, and Brookfield are co-lead founding partners.

The roster also includes Goldman Sachs, SoftBank Corp., Warburg Pincus, B Capital, BBVA, Emergence Capital, and WCAS. Consulting firms Bain & Company, Capgemini, and McKinsey & Company are investors too.

OpenAI said the deployment company will use its capital to scale operations and buy additional firms that can speed up enterprise AI adoption.

AI’s bottleneck moved from access to integration

OpenAI moved to a new competition space. More than one million businesses already use OpenAI’s products and APIs. But as models grow more capable, the bottleneck isn’t access to AI anymore.

It’s integrating that AI into the messy, specific workflows companies actually run on.

The launch comes as Anthropic, OpenAI’s closest rival in frontier AI, has gained ground with enterprise customers through its Claude model family. Last week, Reuters reported that both OpenAI and Anthropic have been in talks through their respective private equity joint ventures to acquire AI services companies.

OpenAI set up the deployment company so that customers could talk to engineers who know where the company’s model skills are going. The idea is that clients build systems designed to improve as new models ship, rather than bolting AI onto legacy processes that weren’t built for it.

A typical engagement starts with a diagnostic phase to identify where AI would create the most business value. The company and client leadership then select a small number of priority workflows.

Forward Deployed Engineers work inside the organization to design, build, test, and deploy production systems that connect OpenAI models to the client’s existing data, controls, and business processes.

The deployment company’s investment partners sponsor +2,000 businesses globally.

The private equity sponsors bring experience in operational transformation and change management, which OpenAI described as complementary to its own technical and product capabilities.

OpenAI’s enterprise expansion gains speed

The deployment unit is the latest move in OpenAI’s aggressive expansion beyond consumer products.

The company generates $2 billion in monthly revenue and counts over 900 million weekly active users, according to figures OpenAI disclosed during its $122 billion funding round in March 2026, as reported by Cryptopolitan. That round valued the company at $852 billion. Its business segment now accounts for 40% of revenue, up from 30% a year earlier.

OpenAI has also committed to massive infrastructure spending. That includes a potential $300 billion Oracle cloud contract over five years, a $22.4 billion CoreWeave deal, and participation in the $500 billion Stargate joint venture with SoftBank and Oracle.
