Graphon

Graphon is an AI infrastructure company based in San Francisco that builds a pre-model intelligence layer for large language models and AI agents. The layer transforms enterprise multi-modal data - including documents, video, audio, images, logs, and databases - into persistent relational memory, giving models access to larger context windows for more accurate and efficient reasoning across complex, interconnected information. The company's approach uses topological, graph-based relationship analysis and is designed to operate at trillion-token-scale enterprise data volumes.

Graphon emerged from stealth in 2025 and raised $8.3 million in seed funding, backed by top-tier investors. The founding team consists of experienced technologists with backgrounds at Amazon, Meta, and leading venture firms.

The company operates in the enterprise software and AI infrastructure sector. Its technical work spans graph-based and topological data analysis, multi-modal data processing, long-context reasoning for LLMs and AI agents, and persistent relational memory systems.
