Why Events
Markets are often described as efficient. In practice, efficiency is a limit — approached, rarely reached. Information enters the world unevenly: a filing, a press conference, a whisper on a forum, a rating change at 7:03 AM. Between the moment an event exists and the moment its meaning is fully priced, there is a window. That window is where we work.
What We Build
We treat event processing as three layers. An ingestion layer that reaches every corner where events are born — exchanges, newswires, broker research, social platforms, corporate disclosures. A decoding layer where models and researchers turn noise into structured, testable signals. An execution layer where those signals become positions, products, and decisions — with infrastructure that fails quietly and recovers fast.
None of these layers is glamorous in isolation. Together, they are the firm.
Our Commitments
Rigor over narrative.
A signal is worth what it can be falsified against. We prefer a boring result that replicates to a beautiful one that does not.
Infrastructure over alpha.
Alpha decays. Pipelines, data quality, and research velocity compound. We invest where the compounding is.
Decades over quarters.
We are building a firm, not a trade. The time horizon is the strategy.

Notes from the work.
The thesis sets the direction; these are the open questions and design choices we live with while building toward it.
Attribution of Research
Every broker view in our system is attributed — not to an institution, but to the individual analyst who authored it. Over time, attribution becomes track record. Track record becomes weight.
The Half-Life of Social Attention
A stock ticker surging on a social platform is an event. How fast it decays — and how it propagates from one platform to the next — is a structural fingerprint we can measure and use.
Aligning Three Clocks
Intraday ticks, end-of-day archives, and corporate action events each live in their own timeline. Fusing them correctly — especially around splits, dividends, and trading halts — is unglamorous, foundational work.
Events Without Words
Not every event arrives as text. Volume anomalies, order-book imbalances, and calendar effects are events too. The ingestion layer must be language-agnostic.
Latency as Ethics
Delay is a form of dishonesty: the longer a system takes to process an event, the further its output drifts from truth. We treat latency budgets as a design constraint, not a performance metric.
