Numina

Numina is a New York City-based urban street-intelligence company (founded 2014, backed by 500 Global and SOSV) whose privacy-first, edge-processing computer-vision sensors measure how people, bicycles, and vehicles move through the public right-of-way. Its "Know Your Streets" platform turns anonymous, aggregated activity into multimodal mobility data for urban planners, municipal departments of transportation, and facilities managers, and exposes that data through the Numina Graph GraphQL API and a developer sandbox. (This profile was seeded as a 500 Global portfolio stub under the placeholder label "CTY"; its Website pointer and 500 Global backing identify it as Numina / numina.co.)

- name: Numina Graph API
  description: The Numina Graph API ("Numina-Graph") is a GraphQL API, authenticated with JWT bearer tokens, that exposes
    Numina's anonymous, aggregated street-activity data. Core objects include Device (a Numina sensor identified by a unique
    serial number) and Behavior Zone (a user-defined polygon used as a spatial filter for analytics). Queries filter multimodal
    traffic volumes spatially and temporally and return pre-computed visualizations. A developer sandbox provides ten days
    of real data from the Downtown Brooklyn (Fulton Mall) deployment.
