Polygon supplies companies & developers with market data for stocks, currencies, forex, and crypto. Polygon provides easy to use APIs to help you build the future of fintech. Powered by Open Source technology. Polygon.io was started by ex-Googlers who have a proven track record of building performant, large scale platforms with clean, intuitive usability. While attempting a project that applied ML to news articles and market data, we were amazed how difficult, unreliable, and expensive market data was. With no solution to our pain points, we decided to apply our deep knowledge of modern tech platforms and infrastructure to solve this for ourselves.
