Company Overview

About Apollo GraphQL

Apollo GraphQL is a software infrastructure company founded in 2016 and headquartered in San Francisco, California. The company created and maintains the world's most widely used GraphQL client and server libraries, and has since built Apollo GraphOS — an enterprise platform for managing, securing, and monitoring production GraphQL APIs at scale. GraphQL is a query language for APIs that enables clients to request exactly the data they need, reducing over-fetching and under-fetching problems common in REST API architectures. Apollo's open-source software is downloaded approximately 25 million times per month, making it the de facto standard for GraphQL development.

Business Model & Competitive Advantage

Apollo has raised $152M in total funding across three rounds from investors including Andreessen Horowitz, Insight Partners, Matrix Partners, and Trinity Ventures. The company reported $37.3M in revenue for the twelve months ending June 2024, with a team of approximately 243 employees. Apollo GraphOS enables enterprises to unify multiple backend services and data sources behind a single "supergraph" — a federated GraphQL layer that any frontend or application can query with a consistent interface. This architecture is used in production by companies including Netflix, Expedia, DoorDash, and Walmart to power their consumer-facing APIs at massive scale.

Competitive Landscape 2025–2026

At GraphQL Summit 2025, Apollo announced its most significant platform expansion, positioning Apollo GraphOS as the data access layer for agentic AI applications — enabling AI agents and LLMs to query enterprise data graphs with the same consistency and governance that human-facing applications rely on. In February 2026, Apollo joined the Agentic AI Foundation to advance open standards for agent-to-API integration. This pivot positions Apollo at a critical inflection point: as AI agents increasingly need access to structured enterprise data, Apollo's graph infrastructure becomes essential plumbing for the agentic enterprise. The company competes with Hasura and StepZen in the managed GraphQL space and with Kong and MuleSoft in the broader API management market.
