BMLL Technologies is the leading, independent provider of Level 3 Historical Data and Analytics for the world’s most sophisticated Capital Markets participants.
Level 3 data captures and displays the trading intentions of all market participants. BMLL clients access this deep data to derive predictable insight. Researchers and quants across global financial services are empowered to truly understand how markets behave and predict the future price movements of securities.
BMLL was founded in 2014. BMLL secured $21 million strategic investment in October 2024, led by Optiver, with participation from CTC Venture Capital and existing investors. This followed BMLL's $26 million Series B investment from Nasdaq Ventures, FactSet, IQ Capital’s Growth Fund and Snowflake Ventures in 2022/2023. Prior to that, BMLL raised $36m through Series A and seed funding rounds.


Highest quality data: BMLL prides itself on providing the highest quality historical data commercially available. Built from the highest quality raw data, the BMLL Level 3, 2, 1 Data is harmonised into a consistent, lossless global format, at nanosecond timestamp granularity with market state, trade condition codes and reference data included in each data set resulting in better insights and analytics.

Accelerated speed to market: Due to the high-quality data and pre-built infrastructure, BMLL users spend 100% of their time on value-add activities, not 80% of their time sourcing, cleaning and munging data.

Lower TCO vs. in house build: BMLL’s cloud native data infrastructure, scalable compute and data warehouse are licensed at a fraction of the cost of an in-house build. All data stewardship and infrastructure & compute management is hosted by BMLL further lowering TCO vs. owning and managing in-house infrastructure.

Integrates with existing workflows: The whole BMLL product suite has in-built workflow integration tooling allowing users to seamlessly combine data, analytics and their research outputs into their existing data workflows.

Trusted partner: BMLL works with the leading trading firms in the world, from hedge funds, market makers, investment banks, global exchange groups and academic institutions. BMLL is ISO27k certified, and Vendor of Record for our historical data products.

World class support: Our support is provided by our team of Client Facing Data Scientists who are all former quants/researchers, enabling clients to scale their research.
