Our mission is to Be the only market data API that projects need

While building trading tools of our own, we became frustrated with the existing market-data APIs, which often provided raw data that we had to rework ourselves, or were just flat-out wrong.

We realized why: there weren’t any API providers willing to put in the grueling effort to enrich and normalize market data across every exchange and asset class. So we started building the Elgon API.

It turned out that many other developers and businesses were looking for the same thing: a dependable source of truth for enriched market data. The API we built for our own tools became a service of its own.

Since then, we’ve been obsessively building Elgon into a fast, production-ready market data API. We believe  the world's markets — stocks, options, crypto, and prediction markets — are converging, and institutions like banks, brokerages, and public companies will increasingly need one comprehensive source of market data.

Our team is committed to becoming the only market data API that teams of all sizes need to trust and build on.
