Two Sigma

Two Sigma is a quantitative investment and trading firm that uses scientific methods, data, and technology to inform its work. Its public materials describe investment management, securities, and real estate activities, with AI integrated into its technology platform and research processes.

In the supplied conference recording, “Tethered: Our Agents Are Us,” Shu Fang is credited to Two Sigma. The recording description presents an internal approach in which employees receive cloud agents operating under their own identities. It describes reusing Kubernetes infrastructure to avoid the permission drift and licensing complications associated with separate agent identities.

The talk also examines accountability and internet access. According to its description, trace headers help reconstruct the chain behind agent actions, while enterprise web grounding within the network boundary and disabled native search and fetch tools constrain web access. The stated tradeoff is approximately a day of search freshness. These architecture details are reported conference claims rather than independently verified company capabilities.
