The integration layer above your specialists. AI-first methodology, principal-level judgment — for decisions that require more than one expert.
Most complex decisions don't fail from missing information.
They fail from missing integration between the specialists who hold it.
A complex decision pulls in lawyers, accountants, consultants, and now AI tools and ecosystems. Each is competent in their lane. None is paid to integrate the picture.
APZ works above your specialists — reading their work in parallel, surfacing inconsistencies, and answering the one question your own team cannot structurally answer: does this decision hold together as one decision, not as the sum of its parts?
Three practice lines, rooted in two decades of cross-industry operating and investment work:
Cross-domain pattern recognition. What today's situation echoes from a different industry or cycle — the pattern your sector experts are too close to see.
AI-augmented diligence. Tracing claims back to authentic sources, deep research, and structured benchmarking — with AI broadening the search and a principal making the call.
Decision integration. Surfacing inconsistencies across expert opinions and operational realities — and putting one defensible recommendation on the table.
No two complex decisions are alike, so the work isn't a fixed checklist. It's a consistent way of thinking — sceptical, source-driven, and built on patterns seen across industries.
Claims traced to primary evidence — EU regulations, national law, local rules, applicable standards, then filings, contracts, and registry data — never to a summary of a summary.
The starting question is always what the material avoids saying. Stress-testing assumptions before accepting conclusions.
Going several layers below the headline — ownership, history, incentives, second-order effects — until the picture actually holds.
Recognising the structural shape of a situation from prior cases, so the non-obvious risk surfaces early.
Comparing against analogues in other sectors and cycles — what looks novel in one industry is often well-understood in another.
AI broadens the search and accelerates the reading. It never replaces the judgment — the conclusion is always human, and accountable.
The discipline isn't a proprietary formula — it's knowing which question matters, and refusing to stop at the convenient answer.
Engagements are confidential, so the work below is described by outcome rather than by client. Each was led personally, at principal level — not all under APZ, but all driven by the same hand. A pattern runs through them: a decision that needed more than one kind of expert, and someone accountable for getting the integration right.
Led a full structural redesign of an airport terminal driven by cost-efficiency — delivering multi-million-euro savings for the client without compromising program, schedule, or safety.
Built contractual and structural safeguards shielding the client and the sponsor, and organised liquid financing efficiently — adding value measured in millions of euros.
Played a central role in the cross-border growth strategy of several SMEs — across multiple continents, from market entry through structuring the expansion.
On several mandates, a precise, engineering-minded approach surfaced risks well beyond the formal brief — in cases preventing failures with serious life-safety consequences.
Directed financial planning, shaped bids and financial models, and supported high-stakes decisions across numerous projects in the tens of millions of euros.
APZ is not a one-man practice. It is the single point of contact to a network built over two decades — law firms, M&A and corporate-finance advisors, private equity houses, engineering practices, and universities across Europe and beyond.
That network is the real asset. Most complex decisions need more than one kind of expert at short notice; the relationships to convene the right ones — and the judgment to integrate what they say — are what two decades of operating and investing across four continents actually build.
The work is led by Zoltán Bagó, Founder & Principal. Civil engineer and economist by training, with a career spanning construction engineering, manufacturing leadership, M&A advisory, and investment management — on projects from €10M to €100M in engineering, energy, food industry, and beyond. An AI-first practitioner, applying AI to valuation, diligence, and strategy since before the current generation of tools made it fashionable.

If you're working through a complex decision and none of your specialists is integrating the picture, you're in our territory.
Principal-level rates — not associate time. Most engagements are scoped to a defined outcome rather than open-ended retainers.
Discrete, decision-specific advisory. Selective availability.
