Algoseek, LLC Information

algoseek provides research-ready market, reference, and research data to the people who build on it: quant trading firms, banks and institutions, fintechs, academic researchers, and two US regulators. Infrastructure came first. Then the data. We build and run the entire path from the exchange feed to your application. Mercury, our proprietary ticker plant written in C++ and Assembly with zero external dependencies, captures every feed and writes the historical archive from the same handler. Every feed arrives four times over, arbitrated across two independent providers and two regions in real time, which is why there has been no client downtime since 2015. That control is what makes the data you research on the data you trade on. The same pipeline, the same schema, and the same security master run from historical backtest to live production, so a strategy survives the whole path without re-sourcing or re-mapping a thing. Up to 90 quantitative fields in every bar, a continuous archive since 2007, and ASID, our persistent security identifier that tracks each instrument through every merger, split, and delisting, cross-referenced to FIGI and ISIN. Explore our data before you talk to anyone. Our data sandbox gives you up to a year of production data, queryable in Python or SQL, with no credit card.
