Data Science

From the first dataset to the recommendation that lands on a CFO's desk, we extract the patterns, quantify the uncertainty, and ship the analysis as a decision, not a deck.

We Find the Signal, Then We Ship It

Quantum Horizon AI's Data Science practice exists to turn complex, messy, real-world data into decision-grade insight. We dig deep with statistical analysis, predictive modeling, and rigorous data engineering, then package what we find as something a non-statistician can actually act on. Notebooks aren't the deliverable; better decisions are.

Every engagement starts where the data does, cleaning, profiling, and understanding before a single model is fit. Then we benchmark approaches, communicate the trade-offs, and deploy whatever makes the call faster, cheaper, or more accurate. From customer segmentation to demand forecasting, causal analysis to experimentation, we don't outsource the thinking, we own it.

Whether you're optimising customer experience, streamlining operations, or hunting new market opportunities, our Data Science work is built to deliver tangible, measurable results, with calibrated uncertainty so you know when to trust the answer and when to gather more data.

The Full Stack of Data Science Work

Six disciplines we draw from on every engagement, from the first exploration through to the production-grade artifact that lives in your business.

Exploratory Data Analysis

Understanding the Data Before Modelling

Profiling, distributions, missingness, outliers, leakage, drift. Before a single model is fit, we know exactly what's in your data, what's wrong with it, and what story it tells. Half of every project lives in this phase, and that's deliberate.

Clean before clever
no model survives garbage data
Statistical Modeling

Inference, Hypothesis Testing, Regression

Linear, logistic, mixed-effects, generalised linear, Bayesian. When the question is "is this real?" or "by how much?", not "predict the next one", we reach for the right test, report the right interval, and resist the urge to p-hack.

Honest p-values
pre-registered, multiple-test corrected
Predictive Modeling

Forecasting & Prediction Pipelines

From demand forecasts to churn scores, lifetime value to defect prediction. Calibrated probabilities, prediction intervals, and clear baselines, so you know when to act on a number and when it's noise. Reproducible, versioned, deployable.

Data Engineering

Pipelines, ETL, & Feature Stores

Analysis is only as good as the pipeline feeding it. We build the data plumbing, SQL, dbt, Spark, Airflow, that turns raw operational data into reliable, governed datasets your analysts and models can both depend on.

data quality is a deliverable
Experimentation

A/B Testing & Causal Inference

Randomised trials, difference-in-differences, propensity scoring, synthetic controls. When you need to know whether something caused something, not just correlated with it, we design the experiment, run the analysis, and write up what's defensible.

Power-aware
we plan the test before we run it
Visualisation

Decision-Grade Storytelling

The chart depends on the audience. We build dashboards, narratives, and one-pagers calibrated to the person making the decision, an executive briefing reads differently from an operations dashboard, and we treat both as deliverables, not afterthoughts.

Audience-first
no clutter, no “just-in-case” charts

What Data Science Looks Like In the Field

A representative slice of the questions our data science work has actually answered, and the decisions those answers unlocked.

SaaS & Subscription

Predicting and Reducing Customer Churn

A subscription business knew it had churn but couldn't tell why. We built a churn model on usage telemetry, surfaced the top three behaviours that predicted cancellation, and ran a controlled experiment that proved a targeted intervention reduced 30-day churn measurably for the at-risk cohort.

Targeted, not blanket
intervention only where it pays back
Retail & Operations

Demand Forecasting Across SKUs and Stores

A multi-store retailer was over-stocking everywhere and under-stocking in the wrong places. We built a hierarchical forecast across SKU, store, and week, with calibrated intervals and a feedback loop that incorporated promotion calendars and weather. Inventory cost dropped without raising stock-outs.

Marketing

Marketing-Mix Modeling & Attribution

A consumer brand was spending across paid, owned, and earned channels with no defensible attribution. We built a mixed-media model with adstock and saturation curves, validated against geo holdouts, and produced a budget reallocation that the CFO would actually sign.

Five Rules That Keep Our Analysis Honest

Data science goes wrong in predictable ways, over-fitted models, p-hacked results, charts that flatter the author. These five operating rules are how we stay out of those traps on every engagement.

Have a Question Worth Answering?

Bring us the question, the messy dataset, and the decision waiting on it. We'll come back with a one-page analysis plan: what we'll measure, how we'll know, and when you'll have the answer.
