Our commitment to developers

Existing financial data offerings aren't built for modern developers. They are too expensive, restrictive, and complicated.

We're building IEX Cloud to break down those barriers and give developers what they need to turn their ideas into reality – and bring more innovation into financial markets. It's a mission that's built into our DNA. At IEX Group, we believe transparency and access to data are critical to fair markets. The Investors Exchange, also part of IEX Group, is known for bringing that philosophy to the stock market by leveling the playing field for investors and bringing transparency to exchange costs.

At IEX Cloud, we're here to make high-quality financial data and services accessible to everyone – starting with you, the developer.
