Why We Built Aion Group

Financial products are full of decisions that can be optimised: how a portfolio is built, how a loan or premium is priced, how risk is hedged, when an order is executed. Too often those decisions still run on spreadsheets, rules of thumb and backtests that look better than reality. We build the algorithms and quant models that improve them, measured honestly against a baseline, explainable to risk and regulators, and yours to keep.

Where We Make an Impact

Pick your field. Not listed? If it's a financial product with a decision to optimise, ask us.

Asset Management

Portfolio construction

Optimise weights under real constraints: turnover, sector limits, ESG rules and liquidity.

→ Better risk-adjusted returns, same mandate
Asset Management

Smarter rebalancing

Rebalance when it pays, not on the calendar: cost-aware triggers and trade sizing.

→ Less turnover, lower costs
Asset Management

Factor & signal research

Test factors and signals on point-in-time data with honest out-of-sample results.

→ Only what survives validation ships
Banking & Lending

Loan pricing

Price per segment and risk profile, balancing margin, volume and expected loss.

→ Higher margin at the same risk
Banking & Lending

Deposit pricing & ALM

Model deposit behaviour and rate sensitivity to set rates and manage the balance sheet.

→ Funding at the right cost
Banking & Lending

Credit risk models

Probability-of-default and loss models that are explainable and validated.

→ Decisions risk and regulators can follow
Insurance

Premium optimisation

Price policies on risk and demand elasticity, not just on the tariff table.

→ Better loss ratio, healthy growth
Insurance

Reserve & claims forecasting

Forecast claims and reserves with models that are measured against the actuarial baseline.

→ Fewer surprises at year end
Insurance

Reinsurance optimisation

Find the reinsurance structure with the best trade-off between cost and capital relief.

→ Capital used where it pays
Trading

Execution algorithms

Schedule and slice orders to reduce market impact and slippage.

→ Lower transaction costs
Trading

Hedging strategies

Dynamic hedging rules tested across regimes and stress scenarios.

→ Risk reduced at a known cost
Trading

Strategy research

Backtests without look-ahead bias, with realistic costs and walk-forward validation.

→ Results you can trust before going live
Fintech & Payments

Fee & product pricing

Optimise fees, rates and plans on usage and churn data.

→ Revenue up without losing customers
Fintech & Payments

Fraud & anomaly detection

Models that flag unusual transactions in real time, with few false alarms.

→ Losses stopped, customers left alone
Fintech & Payments

Liquidity & cash forecasting

Forecast inflows and outflows to keep buffers lean but safe.

→ Less idle cash, no shortfalls

Measured Honestly

Every model is measured against a baseline before it ships: portfolios, prices, risk models and execution alike.

Why Teams Choose Aion

Four principles behind every model we build.

01

Measured, not promised

Typical approach

Impressive results on paper, no comparison with what you do today.

The Aion way

Every model measured out of sample against an agreed baseline or benchmark.

BaselinesOut-of-sampleBenchmarks
02

No look-ahead, no overfitting

Typical approach

Backtests on cleaned-up data that quietly use information from the future.

The Aion way

Point-in-time data, realistic costs and walk-forward validation as standard.

Point-in-timeWalk-forwardRealistic costs
03

Explainable to risk & regulators

Typical approach

A black-box model nobody can explain to the risk committee.

The Aion way

Documented assumptions, validation reports and a full audit trail.

DocumentationModel validationAudit trail
04

You keep the keys

Typical approach

A vendor model you rent, and a permanent dependency.

The Aion way

Your team works alongside ours. You own the code, the models and the know-how.

How We Work

Short, methodical engagements, typically around eight weeks. Your team works alongside ours, so the knowledge stays in-house.

01

Scan

Map the product, the data and the decision; agree the baseline we must beat.

02

Model

Build the algorithm or quant model on point-in-time data.

03

Validate

Walk-forward, out of sample, stress-tested and documented.

04

Hand over

Running in production, explainable, and yours to keep evolving.
