Graphon Raises $35 Million to Give AI Agents a Memory

San Francisco startup Graphon has raised $35 million in Series A funding to fix what its founder calls AI agents' "amnesia" — their tendency to lose track of past conversations and drown in vast, shifting troves of company information.

RRE Ventures led the round, with participation from Energy Impact Partners, Hitachi Ventures, Gaia VC, and HP. The company closed a roughly $8 million seed round earlier this year.

Graphon builds software that lets AI agents store and retrieve information over time. Its founder and CEO, Arbaaz Khan, named the company after "graphons" — a mathematical framework he used during his Ph.D. research into coordinating swarms of robots.

What's wrong with how AI agents remember today?

AI agents can already write code, search databases, and carry out multistep tasks. But they still forget prior context and struggle to make sense of huge, constantly changing corporate data stores.

Khan compared common AI search systems to tearing pages out of a book, crumpling them up, and tossing them into a bin.

"Now when you go searching that trash can, you're just trying to find the pieces to answer," Khan told Business Insider. "You've basically lost all that information because each piece is living on its own."

Graphon's answer is a connected "fabric" of information. Instead of treating a company's documents, videos, and images as isolated snippets, the software maps the connections among them — including where each piece of information came from and when it changed.

In short: context, not fragments.

Who's buying it?

Graphon says it targets two customer groups:

• Individual developers
• Companies with enormous stores of technical and operational data — industrial businesses, financial services firms, and healthcare companies

The product works with off-the-shelf agents. "You can basically point your Claude or GPT or whatever to Graphon," Khan said. "You can push in any amount of data in this, and we literally mean any."

The company says its software is already used by the San Francisco 49ers and HP.

Where does the $35 million go?

Graphon has 20 employees and plans to spend the new cash primarily on hiring engineers and researchers, plus some sales and go-to-market staff.

Khan said the company expects to stay focused on enterprise customers before pushing further into personal devices and consumer products.

For now, the bet is that memory — not raw model horsepower — is the bottleneck holding agents back inside large organizations.
