Data Prediction & Explainability

We build predictive models on your own data, with realistic accuracy estimates and a clear explanation of every prediction. We also audit existing models and develop custom data pipelines that run on your infrastructure.

Where we can help

  • You have years of data, but decisions are still made on gut feeling.
  • You need predictions you can explain to management, customers or regulators, not a black box.
  • Your data has hundreds or thousands of variables and you need to know the few that really matter.
  • A model you already use reports impressive accuracy, but you are not sure it holds up in practice.
  • Data arrives from several systems in different formats and has to be cleaned by hand before anyone can use it.

Service packages

Data & predictive analytics

A predictive model built on your own historical data, delivered with an honest estimate of its accuracy and an explanation of what drives each prediction.

What you get

  • Analysis of your data and its quality
  • Trained model, ready to use on new data
  • Accuracy report with confidence intervals, corrected for selection bias
  • Explanation of the model: the main drivers overall and behind each individual prediction
  • A script that generates predictions with the model from new data in the same format (schema) as the training data
  • Optional, at extra cost: integration of the model into your own code

Typical duration4–8 weeks

From €4,500 + VATincl. 24% VAT: €5,580

What we need from you
  • Signed contract, including an NDA and a data-processing agreement
  • Access to real or realistic (e.g. anonymised) historical data, including the outcome to predict
  • A description of the input data (fields, types, meaning)
  • Agreed output: prediction format, and whether the model is delivered as a script or integrated into your code
  • For integration: access to the relevant code or a test environment

Feature panel & biomarker discovery

Find a small, robust set of features (genes, proteins, clinical, sensor or business variables) that predicts an outcome, and alternative sets with similar performance where the data supports them.

What you get

  • A predictive feature panel with validated performance
  • Alternative panels with similar performance, where the data supports them
  • Explanation of each feature's contribution
  • An analysis report that documents each step, so the analysis can be reproduced

Typical duration6–12 weeks

From €6,000 + VATincl. 24% VAT: €7,440

What we need from you
  • Signed contract, including an NDA and a data-processing agreement (essential for health data)
  • For health data: confirmation of the ethics approval or legal basis for using it
  • Access to the dataset
  • A description of the data, including outcome or phenotype definitions

Model audit

An independent check of an existing model: how accurate it really is, and why it makes the decisions it makes.

What you get

  • Re-estimated performance with confidence intervals
  • Explanation of the model's decisions, overall and per case
  • Findings and recommendations report

Typical duration2–4 weeks

From €1,800 + VATincl. 24% VAT: €2,232

What we need from you
  • Signed contract, including an NDA and a data-processing agreement
  • Access to the model and to evaluation data
  • A description of the input data (fields, types, meaning)

Custom data pipelines & real-time processing

Custom components that collect, validate and transform your data in batches or in real time. They run on your own infrastructure, so your data never leaves your systems.

What you get

  • Data validation and transformation components (batch or real-time)
  • Feature pipelines and integration of models into your systems where needed
  • Deployment on your infrastructure
  • Documentation and handover

Typical durationDefined in the written scope

Price: set in the written scope

What we need from you
  • Signed contract, including an NDA and a data-processing agreement
  • Access to real or realistic data and to the target environment during build and deployment
  • A described, standardised input data schema
  • How often data arrives and how much: expected volume per time frame, typical and worst case
  • An agreed output specification: format, fields, latency or update frequency

Durations count from the day we receive the data or content, after the contract is signed and the first payment is made.

Prices are indicative starting prices excluding VAT. Customers in Greece and private individuals pay 24% Greek VAT. Businesses with a valid VAT number in another EU country are invoiced under the reverse-charge mechanism. The final quote is given in writing once the scope is agreed. Projects up to €2,000 are paid in full when the contract is signed. Larger projects are paid 50% on signing and 50% before final delivery.

Frequently asked questions

Can you build a custom prediction model for my organisation?

Yes. We build models on your own historical data and work with clients across Greece and the EU, in Crete or remotely.

How do you explain what the model does?

Every model comes with an explanation of its decisions: which factors matter most overall, and why each individual prediction came out the way it did. You can show this to management, customers or auditors.

How is the model delivered?

As a script that generates predictions with the model from new data in the same format as the training data. You run it on your own computers or servers, so the model always stays in your systems. If you want it built into your own software, we can integrate it into your code at extra cost, agreed in the written scope.

How is the scope agreed?

Always in writing, in three steps. You send a description, your desired timeline and whether a budget is available. We reply with questions and a written scope and timeline, which we adjust together. Once both are settled, we send a fixed quote. The contract contains the agreed scope and the fixed quote and takes effect when it is signed and the first payment is made. Work starts once we receive the data.

What if we need changes later?

It depends on their size. Small changes (up to about 4 hours of work) are charged at €55/hour + VAT, with a written estimate before we start. Larger changes, such as new features, new data or anything that changes the scope or timeline, go through the standard process as a new request: written scope, fixed quote and a contract addendum. The original scope and price stay protected.

How much data do I need?

It depends on what you want to predict. A few hundred well-recorded historical cases can be enough for a first model. During the written scoping we review a description or sample of your data and tell you whether it is sufficient before you commit.

How do I know the model's accuracy is real?

Every model comes with accuracy estimates and confidence intervals from repeated cross-validation, corrected for the optimism that comes from picking the best of many candidate models. You see the realistic figure, not the best-case one.

What methodology do you follow?

Data projects follow CRISP-DM: business understanding, data understanding and preparation, modelling, evaluation and deployment. Standard packages run as a fixed-price process. Custom projects add milestones and feedback rounds.

Do you work with health or omics data?

Yes, under a data-processing agreement and with confirmation of the ethics approval or legal basis for the data. Every analysis comes with a report that documents each step, so it can be reproduced.

Does our data leave our company?

It does not have to. The finished model and any data pipelines always run on your own infrastructure. Where we process data ourselves, it is covered by an NDA and a data-processing agreement.

What does it cost?

Packages start from €1,800 + VAT for a model audit, €4,500 + VAT for predictive analytics and €6,000 + VAT for feature discovery. The price depends mainly on the size and complexity of the data available. Custom data pipelines are priced in the written scope. The final price is fixed in a written quote once the scope and timeline are agreed.
