Massive is a market-data infrastructure platform built to provide real-time and historical financial data to developers, startups, and trading firms. It delivers institutional-grade market data across stocks, options, indices, currencies, and futures, all via a streamlined API, WebSocket, flat-file S3 access, or SQL query interface. The platform emphasizes low latency, direct connectivity to major exchanges (NYSE, NASDAQ, CBOE, OTC), and data normalization to eliminate survivorship bias and outdated pipelines. Massive positions itself as “modernizing Wall Street” by removing legacy bottlenecks and providing the same quality of market data typically reserved for large institutions, but now accessible to any app builder. The platform also includes extensive documentation, client libraries in Python, JavaScript, Go, and Java, tutorials, and example projects to accelerate integration.
