BMLL Technologies is the leading, independent provider of harmonised, Level 3, 2 and 1 historical data and analytics to the world’s most sophisticated capital market participants, covering global equities, ETFs, futures and US equity options.
BMLL offers banks, brokers, asset managers, hedge funds, global exchange groups, academic institutions and regulators immediate and flexible access to the most granular Level 3, 2 and 1 T+1 order book data and advanced pre and post-trade analytics. BMLL gives users the ability to understand market behaviour, accelerate research, optimise trading strategies and generate alpha more predictably.
Founded in 2014 in the machine learning laboratories of the University of Cambridge, the platform enables researchers and quants across global financial services firms to apply complex statistical techniques to BMLL’s unique big-data sets with applications such as market impact, pre and post trade analytics, order book simulation and compliance. Users no longer need to buy, curate and harmonise data. With BMLL, they gain cost-effective, instant access to a cloud-native Data Science environment via a single web portal, with a long history of the most granular, full order book data across global equities, US equity options, futures and ETFs for back-testing and simulation, delivered directly into their workflows.
In October 2025, Nordic Capital acquired BMLL. The investment was made in close partnership with the management team of BMLL and minority shareholder Optiver, marking a joint commitment to accelerate the company’s next phase of growth. Before this, BMLL secured $21 million strategic investment in October 2024, led by Optiver; $26 million Series B investment in 2022/2023; and $36 million in 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.
What the industry thinks
We are providing traders with unprecedented pre-trade insights to optimize their trading decisions at the point of execution. By seamlessly integrating BMLL’s high-quality data and analytics, we are empowering our clients to achieve better outcomes, enhancing trading performance, managing risk, and meeting their own clients’ demands.
BMLL’s data quality and scalable integration with Snowflake’s AI Data Cloud has supported how we approach algorithmic development. By removing data management barriers, they helped accelerate the development of KCx Spark and bring us closer in our journey towards building KCx Omni, our vision for the future of equity execution.
We chose BMLL as the data provider for Aquis’ Metric Warehouse as it was able to provide both the tick data and the infrastructure that we needed to facilitate the large scale analytics that we were seeking. The granularity of historical data, along with relevant supplementary data points, has made analysis at our end a lot easier and coupled with the ability to overlay member data it allowed for seamless integration with our inhouse metrics.
Optiver traders, quantitative researchers and developers rely on historical data to shape our pricing strategies, making data science and research a key part of our mission to improve markets. The high quality of BMLL's data, their advanced analytics tools and their best-in-class team have together significantly improved our ability to generate insights that influence our strategies. We believe these benefits can extend beyond our firm and provide substantial value to other market participants as well.
BMLL allowed us to bypass the complex and costly process of obtaining data from exchanges. As a result, we could focus our efforts on conducting research to determine usefulness and relevance of data to our specific needs. Having immediate access to the data eliminated any delays that would have otherwise hindered our research efforts. By removing these barriers, our team could dive straight into analysing the data and extracting results.
BMLL has mastered the heavy lifting around the data normalisation process. Second, it's a neutral provider which makes our service even more credible, and it's a cost-efficient service from our perspective. Lastly, and I would say most importantly, BMLL provides excellent quality of support. Our clients can easily navigate fragmented markets. SIX gains immediate insight on the performance of the liquidity providers.
We looked at a number of historical data vendors, and soon realised BMLL is in a class of its own. Accessing BMLL data now enables our clients to do strategy back-testing on high-fidelity data and execute using our real-time data. What sets BMLL apart is the way the data is sourced, saved and curated.
KCx Spark is the first module launched on KCx Omni, our next-generation, event-driven execution platform integrating algo engines, OMS, EMS, TCA analytics, portfolio optimisation, and IOI workflows. The new SOR also leverages advanced quant models and level 3 data from historical market data and analytics provider, BMLL Technologies, with the aim of enhancing algo performance.
As Europe’s 7th largest exchange, we are constantly looking to enhance the liquidity and execution opportunities for our Members. By using BMLL Level 3 Data and advanced analytics we are now able to engage with our Members to compare their trading dynamics on our exchange versus their peer group and to demonstrate that Aquis offers superior trading outcomes for both passive and aggressive strategies. In addition, we are able to evidence our ability to consistently be present at the ‘European Best Bid and Offer’ (EBBO), regularly ranking in the top 2 across European exchanges.
In 2022, we selected BMLL as a partner. By leveraging BMLL’s order book analytics and advanced insights we better understand market microstructure and optimise our trading strategies. Clients will notice improved routing capabilities in the US and EU.
Marcos Carreira, PhD Candidate from the Quantitative Regulation chair at École Polytechnique, and I have worked with many different data providers, and the BMLL Data Lab is one of the cleanest historical data products we have seen. It is very easy to use, and the documentation and support are superb. The book reconstruction will be of great help, especially with all the interruptions to continuous trading that we have seen in the market.
Berenberg’s Data Science and Algorithmic Engineering teams draw on a multitude of sources, including partnering with BMLL, leveraging their Level 3 data to layer market event datasets with client trade data by linking unique order IDs via matching engine timestamps. Level 3 data draws insight into cancellations, amends, quote submissions, order queue details and unfilled orders. This allows Berenberg’s TIA to deliver a robust A|B testing environment across 5 years of market and trade data to efficiently optimise algorithmic performance.
The partnership between Berenberg and BMLL is about democratising access to Europe’s most comprehensive analytics engines and largest data lakes. Overlaying millions of child orders on top of billions of market data points no longer requires an army of quantitative researchers or data engineers. It’s about mapping complex relationships, standardising benchmarks, and giving all market participants, large and small, the chance to produce better outcomes for their clients.
Jefferies has teamed up with analytics provider BMLL Technologies and deploys cloud computing capabilities to carry out detailed analysis, allowing the team to understand on a granular level what happens to the order book when they trade passively or aggressively. We’ve been doing that analysis for a very long time, but it’s now at a far greater level of granularity. We can see which orders move when we cross the spread, for example, rather than knowing that some orders move. We can track those and see where they came from. It enables much smarter decisions, and using that within the algo constructions process is a huge priority for our team.
By partnering with the best content providers like BMLL, we empower firms to access the best, large scale content without the increasingly unnecessary headache of on-premise storage and costly data movement while enabling them to focus resources on value add initiatives.
Congratulations to BMLL and Paul Humphrey who have built the best product to dissect liquidity across European capital markets. Your outstanding product allowed us to analyze the fragmented liquidity pools across Europe. Really impressed by the data quality and analytical capabilities
