357 Main is becoming Node 2: a localized compute facility designed to extend sovereign AI technology to up to 75 qualified virtual clients across the Armonk campus.
Systems / 01—04
357 Main is the operational anchor of a two-building campus: a place where physical occupancy, resilient services, and remote business presence meet.
Dark fiber between 355 and 357 forms the private campus backbone, with client activation subject to qualification.
Excess fiber-optic capacity is being deployed as part of the Node 2 service environment.
Excess amperage and generator-backed building power support the hosted infrastructure design without creating an uptime guarantee.
Available building amenity space is being fitted to host a localized compute facility for qualified virtual clients.
Infrastructure is an amenity
Connectivity and backup power are treated as building systems—not afterthoughts. The result is an address prepared for modern operating requirements, without overstating what infrastructure can guarantee.
Node 2 / Sovereign virtual service
In implementation · Designed for up to 75 clients
Amenity USF, excess amperage, and excess fiber-optic capacity at 357 Main are being converted into a hosted localized compute facility. Node 2 is designed to extend the same class of tenant-controlled sovereign AI technology available to physical-space clients to as many as 75 qualified virtual clients.
Local intelligence
Nate provides diagnostics, configuration, observability, and orchestration for tenant-controlled intelligence. Native Agentic, a planned company not yet formed, will operate Nate; until then, North Castle Ventures handles Nate inquiries.

The dark-fiber campus backbone is designed to connect qualified Node 2 clients to compatible physical space as availability and operating needs evolve.
Node 2 is in implementation, not commissioned or available for activation. Capacity, pathways, security, service scope, pricing, and eligibility remain subject to qualification and contract.
Register Node 2 interest357 Main is being prepared to support the next layer of private, local intelligence. The building's infrastructure provides a credible foundation; the future offering will define the operating model.
Hardware pre-booking, rental or purchase, and Nate deployment by Native Agentic are planned capabilities. They are not currently available for transaction.
Sister buildings / one architect
Vatche Simonian designed both 355 and 357 Main as complementary works within Armonk Professional Center. Their shared material language and site continuity now frame a private dark-fiber backbone connecting Node 1 and Node 2.

Node 2 is an in-implementation service at 357 Main. It uses building amenity USF, allocated electrical capacity, and fiber capacity to host sovereign AI infrastructure for qualified virtual clients.
The current design target is up to 75 qualified virtual clients. That is planned capacity, not current occupancy or a guarantee of availability.
No. The service is in implementation and has not been commissioned for activation. Interest is being registered while technical, security, commercial, and acceptance terms are completed.
Node 2 is designed to provide the same class of sovereign AI technology without requiring a dedicated suite. Nate diagnostics and software orchestration will be operated by Native Agentic, a planned company not yet formed; until then, North Castle Ventures handles Nate inquiries. Final configurations are client-specific.
The dark-fiber backbone between 355 and 357 is designed to support connections to compatible physical space as campus availability and client requirements evolve. Activation is subject to pathway, security, capacity, and contract qualification.
No. 357 Main is fully leased. Node 2 uses amenity space for hosted infrastructure and is separate from physical-suite leasing.
