| Company | Description | Amount | Stage | Date | Website |

| Massive | As AI systems consume the public web faster than it can be cleanly delivered, Massive operates the access layer that keeps that data flowing. The demand has two shapes. First, training: frontier and applied models need web data at a scale and geographic spread that ordinary collection methods cannot sustain without getting blocked or geo-cloaked.Second, grounding: agents, retrieval pipelines, and AI answer engines need real-time access to live pages so their outputs reflect what is actually on the web right now, not a stale index. Massive serves both from one foundation. A network of real consumer devices in 195+ countries routes requests as organic local traffic, so destination sites return the same content a real user in that geography would see. On top of that network sits the Web Render API, which delivers fully rendered pages, search-engine results with AI Overview and People-Also-Ask retrieval, and completions from frontier models returned with their sources, all available as first-class markdown built for LLM prompts. The network is ethically sourced, with every device opted in through the Massive SDK, and the platform is SOC 2 audited, GDPR compliant, and AppEsteem certified, with a full audit trail from source to request. Massive helps AI labs, agent builders, answer-engine and RAG teams, and large-scale data operations turn the live web into clean, dependable input without fighting blocks, geo-restrictions, or the brittleness of stale data. | $11M | Seed | Nov 30, 2021 |  |
