About Us

Bringing Science into Retail Trading

It takes lots of data, speed, and scalability to offer a reliable scientific solution to the ever growing retail user base in financial trading. We solve this problem by bringing in heavy experience from database, AI, and capital markets. Together, we have built an extremely optimised time-series database called “MarketStore.” With MarketStore, we are achieving similar speed scores to the institutional level offering but in a much more scalable way. Our team is well positioned to bring the scientific solution to retail traders globally.

“MarketStore” – Hitoshi’s Story

One Fall afternoon in 2014, while working in Downtown New York, I was contemplating the uses of our multi-million dollar database. It struck me that although our product was being used in one of the biggest financial institutions in the world, that institution was still burdened by the inefficiencies of a general-purpose database.

A year later, we at Alpaca experienced the same problem for our retail trading applications. Our solution was to build our own database. Starting from the ground up, we built the most efficient database for time-series market data analytics by leveraging cutting edge hardware and software technologies. We know that our product is one-of-a-kind and we are confident that we will continue to prove its value. We are dedicated to achieving the best performance and delivering the best value applications to our customers.
