Unique combinationof product, growth and AI leadership

You need progress.
And someone accountable for it.

You need a direction you can defend.

The board is asking about AI. Your team has ideas. You need to choose the few investments that fit your business, with clear costs, risks, and measures of success.

Pilots are running. Progress is stalling.

You need someone to align product, commercial, and operational teams, make the difficult trade-offs, and take useful work into production.

The agenda cannot wait for a hire.

You need experienced leadership through a transition—or a senior owner each week while your existing team delivers.

The right level of leadership
for the job ahead.

I take on a few focused collaborations. We agree the remit, decision rights, time commitment, and success measures before starting.

FractionalTypically 1–2 days a week

A senior owner, every week.

Your team is in place. I join your leadership rhythm, own the agreed AI priorities, guide investment and vendor decisions, and keep delivery moving.

You get: a clear roadmap, regular decisions, and accountable delivery with your team.

Fractional engagements in Finland start from €6,000 per month + VAT.

InterimTypically 3–6 months

Lead the transition.

An executive gap or critical change needs dedicated ownership. I step into a defined mandate, align the organization, lead execution, and prepare the handover.

You get: executive ownership, agreed milestones, and continuity for your permanent team.

Make the result visible.

Review the measures we agreed: adoption, time saved, cost, quality, or revenue contribution. Use the evidence to decide what scales.

Ville Ylläsjärvi, founder of Herman Foundry

I’ve built and scaled a company.
Now I build with agents.

I co-founded Haltian and helped grow it past €19M in revenue and 100 people, following work at Nokia and BMW Designworks. That experience shapes how I connect product decisions, commercial reality, and execution.

At Herman Foundry, I build with AI agents in practice. In your company, I bring that experience into the context of your team, your customers, and the outcomes you need.

Based in Levi, Finnish Lapland. Working globally, with on-site collaboration agreed around the mandate.

Working with an AI leader

What does a fractional AI leader do?

A fractional AI leader is a senior executive who owns your AI agenda part-time, typically one to two days a week. I join your leadership rhythm, own the agreed AI priorities, guide investment and vendor decisions, and keep delivery moving with your team, without the cost of a full-time executive hire.

What is the difference between fractional and interim AI leadership?

Fractional leadership is ongoing and part-time: a senior owner every week while your team is in place. Interim leadership is a dedicated mandate, typically three to six months, when an executive gap or a critical change needs full ownership. I align the organisation, lead execution and prepare the handover to your permanent team.

How is an AI leader different from an AI consultant?

A consultant typically advises and hands over a report. An AI leader takes accountability for the outcome: agreed decision rights, priorities and success measures, and the work of taking useful AI into production with your team. The remit, time commitment and measures are agreed before we start.

How much does it cost?

Fractional engagements in Finland start from €6,000 per month plus VAT. The AI Impact Sprint is €25K flat for four weeks, plus VAT. Interim mandates, and engagements outside Finland, are priced per engagement. The sprint is often the cleanest way to scope a longer mandate.

Do you work outside Finland?

Yes. I am based in Levi, Finnish Lapland, and work remote-first with companies globally. On-site collaboration is agreed around the mandate.

How do we get started?

Book a short fit call. You share what is at stake and what is stuck, and I tell you whether a fractional role, an interim mandate or a focused sprint fits, or whether another option would serve you better. If you want to start on your own, Strategist gives a first view of your company’s AI opportunities.

What needs to change
in your business?

Tell me what’s at stake, what’s getting stuck, and when you need progress. We’ll discuss whether a fractional role, an interim mandate, or a focused sprint fits.
