Semantics What data and operations mean and how they relate
Give AI access to the systems that run your business
Every company needs a domain model for AI. Apollo GraphOS helps you build yours over the systems you already run: one architecture for agents, AI experiences, and applications.
Trusted by enterprise leaders
A shared foundation for every AI initiative
As AI takes on more work, your company needs a consistent way to make its services discoverable, explain how to use them, and govern access.
A domain model provides that foundation across the agents and applications you choose. As you add agents and change AI tools, the work you put into connecting and governing your services carries forward.
A domain model optimizes your APIs with the meaning and controls needed to use them.
Policy Who can see and do what, enforced on requests
Discovery A place to discover the capabilities needed for a task
See a domain model in action
Intuit built an agentic system to optimize marketing programs in real time. Running it in production required a domain model and access controls. GraphOS is the foundation that lets Intuit's agents work accurately and safely.

Enterprise teams trust Apollo
Enterprises rely on Apollo to unify their APIs into a single, discoverable, and reusable platform that adapts to any use case. Product development teams can work independently, reuse APIs, and deliver new features lightning-fast while benefiting from modularity, optionality, and autonomy.
“Now our agents can analyze spend against results and propose a change in real time, because GraphOS Agent Services gives them access to only what they need and keeps an audit trail of everything. That's the only way we'd trust giving them this kind of authority.”
Chris Miller
Head of AI Marketing Futures Intuit

“Having Apollo and GraphQL allowed us to accelerate our AI work by providing that base capability of the data we needed for the AI agents. We were able to free up our resources to focus on just the AI-specific problems.”
Jeffrey Russom
Principal Software Engineer Indeed
“We wanted to move from our monolithic architecture to a modern distributed architecture that allows us to deploy new features independently. When teams have more autonomy, the speed of delivery is greatly improved. We also want to ensure the consistency of data, access to that data, and treat all of our clients as if they are the same consumer of the same data.”

“We want our entire business on the supergraph because we think it’s better than those dusty old REST API’s. We wouldn’t have an accurate online shopping experience without the supergraph.”
Stephan Lonntorp
Senior Engineering Manager Volvo Cars

“Really, it’s speed and agility that’s going to take you to the next level, rather than the technology itself. That’s why I get so excited about the supergraph.”
Deep Varma
CTO Varo
“Apollo GraphOS is a key platform for the development team to work softly with GraphQL. It provides a bunch of tools and APIs that allow us to establish a secure development pipeline to compose and deliver new pieces to our supergraph.”
Marcelo Nalon
Staff Engineer Globoplay
“Had contracts not existed, Wayfair would’ve invested 100s of person hours building out custom infrastructure to replicate what we get “built-in,” freeing up time to focus on Wayfair customer needs and developer experience.”
Mark Faga
Senior Staff Software Engineer Wayfair
“Using Apollo’s unified graph, Expedia rebuilt our entire trips experience 3x faster than our old approach. Adding new trip features to all our apps now takes days rather than months.”
Rick Fast
SVP of Engineering Expedia
“We introduced a new subgraph in the federated graph [for backend compliance logic when Zillow was becoming a brokerage], and it was a complete success … 70 systems migrated without any advance, and we had the deadline, right on the dot.”
