Notice (notice.co) is a private-market data and investing platform founded in 2021 by Philip West and Tyson Hendricksen and headquartered in Wilmington, Delaware. It publishes Notice Price, a real-time evaluated price for private company stock recomputed every three seconds from private market transactions, indications of interest and public comparables, alongside company profiles, rankings, industry screeners and the Notice.co 50 Index (N50) covering 6,000+ private companies. Its commercial surface is a RESTful enterprise API that imports that same real-time data - Notice Price, verified trades and indications of interest - into a subscriber's own systems, plus a live OAuth-protected MCP server at api.notice.co/mcp and a free embeddable chart widget. Notice shares trade on secondary marketplaces including Forge and Nasdaq Private Market.
