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.
Interim & fractional AI leadership
Turn AI ambition into business results.
I help CEOs decide where AI can improve their business—and lead the product, growth, and operational work to make it happen.

When to bring me in
You need progress.
And someone accountable for it.
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.
Work together
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.
01 / Fractional · Typically 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.
Explore fractional leadership ↗02 / Interim · Typically 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.
Explore interim leadership ↗Need to establish the direction first?
The AI Impact Sprint scopes the opportunities, priorities, and roadmap in four weeks.
How the work starts
A business mandate.
A visible delivery rhythm.
Choose what matters.
Understand the business, customers, team, and data. Agree which opportunities deserve investment and which should wait.
Put the work into use.
Set owners and milestones. Work with your team on implementation, adoption, and the decisions that block progress.
Make the result visible.
Review the measures we agreed: adoption, time saved, cost, quality, or revenue contribution. Use the evidence to decide what scales.

Your counterpart / Ville Ylläsjärvi
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.
