The founder
David Jujan, 25 years of experience in the lift industry
David Jujan devoted 25 years to the vertical-transport sector, successively with OTIS and Schindler, two of the most important players in the global market.
His career spans the entire chain: sales engineer, head of maintenance and repair in Geneva, head of sales for Western Switzerland, then agency director with full P&L responsibility for more than ten years. He ended his employed career as head of sales and products for OTIS Switzerland.
This experience has a concrete consequence for his clients: he knows how prices are built, how contracts are written, how portfolio renewals are decided and how repair quotes are costed. He knows exactly where the room for negotiation lies, because he has practised it himself.
AA Consulting was born in 2025 from a simple observation: the technical side of lifts is an expert’s business, and owners almost never have access to an expert who works exclusively for them.

Our commitments
No industrial affiliation
We represent and recommend no manufacturer. Brands mentioned on this site only illustrate the breadth of our technical experience.
No interest in spending
Our remuneration depends neither on the value of the works decided nor on the supplier chosen. That is the condition of an honest recommendation.
Written recommendations
Every finding is documented, quantified and reasoned. You must be able to defend a technical decision before an assembly or a board.
Dated deliverables
The detailed digital report is delivered within 72 hours of the visit. It is a contractual commitment, not an intention.

Our values
Three principles applied to every engagement
Safety
Rigorous checks that protect users and technicians alike, keeping every installation at the expected level of requirement.
Sustainability
Favouring targeted modernisation, energy efficiency and durable components over systematic replacement.
Ethics
No affiliation with any manufacturer or maintenance company. Every recommendation is reasoned, quantified and defensible before a general meeting.
Method
How an engagement unfolds
Analysis of the situation
Documents, contracts, invoices, inspection reports and breakdown history: we start from what already exists to understand where your money actually goes.
On-site diagnosis
Visit of the installation, technical survey, tests and meeting with the current maintenance company. The diagnosis is established without complacency and without commercial interest.
Report and recommendations
A digital report delivered within 72 hours: findings, priorities, possible alternatives and clear budget estimates, ready to use in a meeting.
Negotiation and follow-up
We run competitive tenders, analyse the offers, negotiate on your behalf and follow the works through to handover. You keep the decision.
What we do
Our services
Audit & technical assessment
A complete and unbiased diagnosis of your installation: actual condition of the equipment, compliance, safety, costs and action priorities, with a digital report within 72 hours.
Learn moreMaintenance contract analysis
We decode your contract line by line: what is really included, what is excluded, what will be billed on top, then we renegotiate on your behalf.
Learn moreCost optimisation
Lastingly reduce the operating costs of your portfolio without compromising safety or availability. Average observed reduction: 20%.
Learn moreRepair quote analysis
Before you sign, we verify the diagnosis, the hours, the parts and the price. A quote challenged in time always costs less than a poorly framed repair.
Learn moreLift modernisation
Modernise rather than replace: we compare at least three companies, analyse the solutions and negotiate before award.
Learn moreLift replacement
From technical analysis to award: calls for tender, technical and financial evaluation, negotiation, then site supervision through to handover.
Learn moreSpecifications & project management
Define the requirement precisely, compare what is genuinely comparable, and avoid offers dragged down on non-negotiable items.
Learn moreConnected lifts & IoT
Monitor, anticipate and objectify: 4G remote monitoring, operating data and maintenance management outside the traditional model.
Learn moreSafety & compliance
Standards, mandatory inspections, compliance upgrades and owner responsibility: what to know, anticipate and document.

A first conversation is often enough to see clearly
Describe your situation: number of installations, current contract, issue encountered. We come back to you with a technical answer, not a sales pitch.
