About

Jakub Grzesiak

Jakub Grzesiak

LinkedIn

Ten years as CTO at Albacross, a B2B SaaS company I co-founded. Production AI in the core product, a proprietary data set we built ourselves, enterprise customers under GDPR, 3B+ events a month. I led the technical side of an acquisition we made along the way.

"Jakub aligns technology with business and thinks several steps ahead. He championed innovation by leading AI adoption, connecting teams, and communicating clearly. Technical depth plus relentless execution."

Product Owner · Scaleup · LinkedIn Recommendation

Today I run Luxdone, an AI-native company, and advise a small number of founders at a time. Architecture, senior hiring, AI strategy, the calls that are hard to make alone. You get an operator as your advisor, not a career consultant.

  • •AI strategy guidance

Embedded leadership

Fractional CTO

When the technical side needs ownership at a level you don't have in-house yet, I step in.

FAQ

How does advisory actually work?

We shape it around your situation. Some founders want a standing call and async access for the decisions in between, others reach out when something big is on the table. We agree the rhythm together and it changes as your company changes.

Do I need advisory or a fractional CTO?

Most founders need advisory. You have a team that ships, what's missing is someone senior to pressure-test the big calls. Fractional CTO is for when the technical side needs ownership at a level you don't have in-house yet. I take a small number of those engagements, when the fit is right.

What if our team lacks AI expertise? Do we need to hire AI specialists?

Don't hire AI specialists yet. Start with the team you have. We pick 1-2 AI tools or features that fit current workflows and ship them. The team learns by doing, not in workshops. Hiring an AI specialist comes later, after you know which role you actually need.

Do I need to commit long-term?

No. There is no long-term commitment, you can walk away anytime. You stay because the value keeps showing up, not because a contract makes you.
