Cadogan Eaton
We build the infrastructure that makes trading systems faster, more reliable, and easier to measure.Cadogan Eaton is a quantitative engineering firm. We specialise in trading infrastructure, data platforms, and revenue systems for teams that need to move faster than they can hire.
What We Do
Trading infrastructure & systems engineering
Low-latency market data pipelines, execution instrumentation, risk monitoring tooling, and operational dashboards. We build the systems your trading desk depends on — and the observability to know when something is wrong before it becomes an incident.Measurement & data platform engineering
Event pipelines, analytics layers, attribution infrastructure, and reconciliation systems that give your trading, finance, and marketing teams numbers they can actually trust — and defend to a CFO.Platform & integration delivery
From scoping to production: API-first builds, third-party integrations, and automation that replaces manual processes. We ship, instrument, and hand off — with the documentation to prove it works.
Case Study A
Trading firm, multi-strategy: Inherited a market data pipeline with no normalisation layer and no timestamping discipline. Rebuilt ingestion and normalisation architecture. End-to-end latency from feed to signal reduced by 60%. Monitoring gaps that had caused two prior incidents were eliminated.Case Study B
Payments client, mid-market e-commerce: Identified BIN routing misconfiguration and 3DS over-triggering. Rebuilt retry logic and payment provider routing rules. Approval rate increased from 71% to 78% in 60 days.
Where We Focus
Trading & capital markets — Low-latency market data pipelines, order routing and execution instrumentation, risk monitoring tooling, PnL attribution systems, and operational dashboards for teams where milliseconds and accuracy both matter. We have seen enough trading stacks to know where the problems are before we start.Payments & fintech — Approval rate optimisation, payment orchestration, reconciliation infrastructure, fraud signal integration, and checkout performance. From retry logic to BIN routing to 3DS calibration — the details that move the approval rate number.Advertising & media — Attribution infrastructure, incrementality measurement, bid optimisation support systems, and data products that make your ROAS numbers defensible, not just impressive.Digital marketing & growth — Experimentation frameworks, lifecycle automation, personalisation infrastructure, and analytics that connect acquisition spend to downstream revenue.Application & platform builds — End-to-end product delivery: scoping, architecture, engineering, and launch. For teams that need it built right the first time.
Team & Outcome
Senior specialists, not generalists
Our team brings deep domain knowledge across trading systems, data engineering, and quantitative infrastructure. Collectively 280+ years of experience — meaning your project is staffed by people who have done this specific thing before, not people learning on your dime.What engagements typically produce:
→ Trading systems with measurable latency improvements and real-time observability
→ Reconciliation accuracy that closes the gap between your OMS, prime broker, and risk system
→ Approval rate improvements of 2–6 percentage points for payments clients
→ Attribution accuracy that makes ROAS defensible to your CFOWe define success metrics before we start. You should be able to measure whether we delivered.
