Fractional Head of Data

Home About Work Fractional HoD 🇫🇮 Suomeksi
Service

Senior data leadership.
Without the headcount.

Your SME generates data. It shapes your customers, your risk, your operations. But hiring a full-time Head of Data or Chief Data Officer is expensive, premature, and often the wrong fit at your stage.

I work with you one or two days a week — embedded in your team, aligned to your goals — bringing the statistical rigour and open-data methodology of a senior data scientist without the full-time cost.

data first — public datasets as competitive intelligence

The gap

What SMEs face. What I solve.

The problem

  • Data piling up with no systematic analysis
  • Dashboards that show what happened, not why
  • No capacity to build forecasting or risk models
  • Regulatory and public data going unmonitored
  • Decisions made on point estimates — no uncertainty quantified

What I bring

  • Bayesian models that expose uncertainty explicitly
  • Open data synthesis as competitive intelligence
  • Probabilistic forecasting with confidence bounds
  • Data strategy aligned to business decisions
  • Research-grade analysis at consultancy speed

To protect quality I take on only a few fractional clients at a time — openings are currently available.

A risk-free start

My promise to you.

Guarantee

Satisfaction guarantee

If the fixed-scope audit doesn't surface at least its fee's worth of clear, actionable value, you don't pay for it. The risk is mine, not yours.

Flexibility

No long contracts

The fractional engagement runs month to month, cancellable on 30 days' notice. You're never locked in — we continue only as long as I'm adding value.

On the house

Free analysis upfront

Before I invoice a single euro, I pull one non-obvious finding from an open data source in your sector — and show it to you. You see the work before you commit.

Free gift · €500+ value

A tailored mini-analysis + whitepaper

Book an intro call and I'll run a free mini-analysis on one open data source of your choice ahead of time, and send it alongside my whitepaper on Bayesian causal inference. A concrete sample of what you get — no strings attached.

Best fit

Who this is for.

Data-generating SMEs

Any organisation with data but no internal senior statistical capacity.

Let's find out if this fits.

The first conversation costs nothing — and you leave with a free upfront analysis. We discuss your data, your decisions, and whether a fractional engagement makes sense for your stage. The audit is satisfaction-guaranteed, and the fractional engagement carries no lock-in.
