Zero end-user downtime
Fully redundant infrastructure. Regional redundancy means clients have never lost access to data.
From trading floor to data company
algoseek started inside a quantitative hedge fund where the founders had spent nearly a decade building trading systems. The market data they were buying from established vendors was expensive, and on close inspection, unreliable. So they built their own.
2006
First ticker plant
The founders write a proprietary ticker plant to power their own quantitative trading systems. It works. They keep building.
2015
algoseek launches
Spun off from the trading fund after eight years of successful high-frequency trading. First product: the Equity TAQ Minute Bar.
2017
Futures and options
Product coverage expands to aggregated futures and options data across CME, CBOT, NYMEX, and COMEX.
2018
Reference data
Security Master File and Corporate Event History launch after a full year of development. The proprietary ASID identifier tracks every ticker change, merger, and delisting.
2020
Data services
algoseek begins managing data infrastructure for other firms. Fellow data vendors start outsourcing their own storage and delivery to algoseek.
US Regulator
Largest infrastructure deal
algoseek beats out all the other financial market data firms to win a deal to build large real-time data infrastructure for a US regulator, providing custom equity SIP and OPRA feeds.
Bulge bracket bank
Custom institutional feeds
A bulge bracket bank selects algoseek to build custom OPRA feed and equity feeds for its global index desk.
2021
ArdaDB
algoseek launches a cloud-based SQL database allowing full SQL search over the entire universe, with the option for dedicated servers for complete privacy.

Sandbox
algoseek launches the Sandbox, giving prospects and clients a place to explore data, run queries, and evaluate datasets before committing.

Our team
The people behind the data
The founding team has over 140 years of collective experience in financial data, trading systems, and exchange infrastructure. algoseek is bootstrapped, employee-owned, self-funded, and profitable. There are no outside investors and no board to answer to.
Technology mind, service heart
“
When there is a data problem, time is literally money. The people who designed our infrastructure are the same people who maintain it and support clients directly.
We built this infrastructure because we needed it for our own trading. That origin shapes everything: the engineering, the support, the pricing.
Zero
Divergence
Historical data is the direct capture of the real-time feed. When you move from research to production, the data does not change.
Your research is yours
Derived data from your research is your IP. algoseek does not claim it.
Real money on the line
Dedicated support is always available for real-time clients. When a feed goes quiet during a session, response is immediate.
Packages grow with you
New datasets get added to existing packages automatically. Updates to existing datasets roll in without any change of fee.
