Ephemera AB builds systematic research and machine-learning systems, drawing on more than a decade of work in the field.
Capabilities
We offer consultancy in quantitative finance and AI, alongside bespoke AI products built to order. We work end to end, from raw data to a system running in production. Engagements are small, senior and hands-on.
Systematic strategy development on futures and equities, evaluated to the standard a trading desk applies.
Machine learning and language-model systems built for real workloads rather than demonstrations.
The layer everything else stands on: ingestion, storage and pipelines that stay correct as they grow.
Approach
We keep the raw record rather than a cleaned summary, so that a cleaning decision can be revisited when a result looks wrong. That is what the pipelines and quality checks are for. Over 200 TB and counting.
Anything that might carry predictive power is considered, not only price and market data. The target is diversified returns rather than one strong signal, and that governs how signals are combined and sized.
Automation is worth the effort where a task is repetitive and well defined. Machine learning and language models are applied on that basis.
Reproducibility and correct data are what a result rests on. Any figure can be regenerated from the code and data behind it, and traced back to where that data came from.
Ephemera builds and runs its own AI products. Each one came out of our own research work and is in daily use.
Contact
We take on a limited number of engagements at a time. The best first message is a short description of the problem and what a good answer would let you do.
