MemVerge
MemVerge is a Milpitas, California AI infrastructure software company that started out virtualizing DRAM and persistent memory into pooled 'Big Memory' and has since pivoted toward the AI era. Its Memory Machine products maximize GPU utilization through memory tiering, pooling and transparent checkpointing, and in 2025 it launched MemMachine, an open-source AI memory layer that gives LLMs and agents persistent episodic, profile and procedural memory across sessions, models and clouds. Founded in 2017 by CEO Charles Fan, CTO Yue Li and chairman Shuki Bruck, the company has raised about $43.5M from investors including Intel Capital, Cisco, NetApp, SK hynix and Lightspeed.
