AI consulting
that actually ships.
For companies exploring AI, stuck in pilot mode, facing compliance pressure, or recovering from failed vendor promises - we bring the technical leadership to design, build, and deploy AI systems that work in the real world.
30-min call. No pitch. You leave with one concrete next step - even if it’s not us.
AI means different things depending on where you’re starting.
You don’t need a million-euro transformation plan to start. You need clarity on what is possible, what is risky, and what should happen first.
Exploring AI
You know AI could help, but you're not sure where to start.
Stuck in pilot mode
Your AI experiment worked in a demo, but never reached production.
Burned by vendors
A vendor overpromised, underdelivered, and left you with little to show.
Compliance pressure
EU AI Act and GDPR requirements are becoming impossible to ignore.
Talent gap
Your team lacks the senior AI leadership to execute safely.
Budget uncertainty
You need to know whether AI is a contained project or a major investment.
Start with an AI readiness audit. Know what is possible before you commit.

AI rarely fails for one reason.
Sometimes the data is messy. Sometimes the vendor overpromised. Sometimes the demo worked, but nobody could get it into production.
Sometimes the team has the ambition but not the AI leadership. Sometimes compliance was ignored until it became a blocker.
The common thread: AI was treated like a tool purchase instead of a business-critical system.
Failure modes we address:
- → Unclear business case and inflated ROI claims
- → Poor data quality and disconnected systems
- → Fragile demos that never reach production
- → Skill gaps inside the existing team
- → Weak delivery ownership and vendor ghosting
- → Compliance and risk discovered too late
- → Budget uncertainty and scope creep
AI Failure Map - why projects stall before production
Fix the foundation. Then add AI.
AI is not a tool purchase. It is a business-critical system. We move deliberately from readiness to foundation, architecture, build, governance, and handover.
Readiness
We define the business objective, workflow fit, data availability, risk level, and expected value before recommending anything.
Foundation
We assess and clean the data, map systems, clarify ownership, and identify what must be fixed before AI can work reliably.
Architecture
We design the technical approach: build vs buy, model selection, integrations, security, monitoring, and human oversight.
Build
We ship working systems: automation, retrieval, model workflows, agentic integrations, internal tools, or production AI features.
Handover
We document, train, and transfer ownership so the system can operate without us.
Built with standards, not guesswork.
Every engagement follows operating procedures built from engineering leadership, AI delivery, security, and compliance practice. You see the work, the risks, the decisions, and the trade-offs.
AI Readiness SOP
SOP-1What we check
Business objective, data availability, workflow fit, risk level, expected value, and build-vs-buy decision.
What you get
Readiness score, feasibility matrix, workflow map, risk register, and 30/60/90-day roadmap.
Data Quality SOP
SOP-2What we check
Source systems, ownership, duplication, completeness, access controls, and source-of-truth confidence.
What you get
Data inventory, quality score, cleanup roadmap, privacy notes, and AI readiness impact assessment.
Production Readiness SOP
SOP-3What we check
Architecture, integrations, deployment path, monitoring, fallback plan, human oversight, and maintenance owner.
What you get
Production checklist, architecture notes, test plan, monitoring plan, risk controls, and handover runbook.
Security & Compliance SOP
SOP-4What we check
GDPR impact, EU AI Act classification, data retention, vendor risk, audit trail, and model/tool controls.
What you get
Risk summary, documentation gaps, compliance roadmap, control checklist, and escalation points for legal review.
→ Weekly artifacts
Progress updates, diagrams, decision logs, and risk registers.
→ Visible trade-offs
You see what we recommend, what we reject, and why.
→ Clean handover
Runbooks, ownership model, training, and support path.
Four ways to move AI from idea to reality.
Start with clarity, bring us in to build, add senior AI leadership, or address compliance before it becomes a blocker.
We diagnose. You decide.
A structured audit of your data, systems, and AI readiness. You'll know what is broken, what AI can actually do, and what to fix first.
- + Data health score and quality assessment
- + Process map with bottlenecks quantified
- + AI reality check - possible vs hype
We build. You ship.
Full implementation - data cleanup, pipeline building, AI layer on top. We architect and ship working systems, not slide decks.
- + Clean data infrastructure
- + Working AI systems in production
- + Team enablement and documentation
Senior AI leadership. Part-time commitment.
You need a CTO who understands AI and can lead the team. We step in hands-on: architecture, delivery, mentorship, and board-ready decisions.
- + Engineering leadership and architecture ownership
- + Vendor evaluation and build-vs-buy decisions
- + Team mentorship and capability building
AI compliance that doesn't slow you down.
EU AI Act compliance isn't a checkbox - it's a capability. We bridge technical implementation and regulatory understanding so your AI ships legally.
- + AI system classification and risk assessment
- + GDPR + AI Act dual compliance audit
- + Compliance roadmap and documentation

Words from the people I’ve worked with
"Jacek was a great person to work with. Highly capable and efficient, understands the development landscape intimately. A great addition to any large or small scale development team."
"One of the most focused and relaxed people I have ever had the pleasure to work with. Laser sharp, goal oriented, and super helpful at the same time."
"Jacek's technical knowledge far surpassed that of others and he was of tremendous benefit to the project. Brought very useful real-world development perspectives."
"Extremely talented and well rounded. Has a "nothing is impossible" attitude and always strives to find innovative and efficient solutions to any problem."

I build AI systems.
I don't just advise.
I’m Jack Trefon. 28 years building technology - 15 in leadership roles as CTO and Head of Engineering. The last 4+ years focused on AI, from custom model work to large-scale agentic integrations.
I don't sell courses. I don't wrap ChatGPT and call it a solution. I architect, build, and ship working AI systems.
I’ve led teams at Logiswift, CAFU, DEX Crypto, and Azolver - building systems that handle millions of transactions with 99.99% uptime. Based in Spain, working globally.
