About Jutro

The work starts with people, not technology.

Jutro is a founder-led AI systems partner. We start with the people, pressures and workarounds around a business problem, then build only the technology that has a useful job.

Why Jutro

Better today. More ready for tomorrow.

Jutro means tomorrow in Polish: improve something real today and leave the business better prepared for what comes next.

That can mean better workflows, stronger decision support or testing where AI creates measurable value. In every case, people must understand the system, question it and remain accountable.

Mario Leśniewski

About Mario

I have spent my career finding clarity in messy situations.

My background spans law, product strategy, design and delivery. Across those roles, the same work kept returning: listen carefully, make sense of incomplete evidence, align people around a direction and turn it into something real.

I ask direct questions, speak plainly and make the reasoning visible. If the evidence is weak, I say so. If a simpler solution works better, I recommend it.

Founder-led by design

You work with the person responsible for the recommendation.

I lead every engagement from diagnosis through evaluation. When specialist expertise is needed, I bring in the right people, explain their role and keep accountability clear.
