Diligence
Technical-commercial diligence, operational assessment, management credibility review, programme risk analysis, and acquisition red-flag reporting.
Private technical-commercial advisory
Quiet judgement
for complex assets.
Onça Partners advises private clients, investors, boards, and niche corporations on technical-commercial diligence, special situations, and recovery assignments across maritime, aviation, and advanced mobility.

Confidential by design
Positioning§ 01
Built for situations where generic advice is not enough.
When capital, reputation, engineering reality, and stakeholder pressure converge, decisions need more than conventional consulting. Onça Partners brings operating judgement, technical literacy, and commercial discipline to complex asset-backed situations.
We are engaged when the answer must be defensible in the boardroom, credible on site, and executable under pressure.
Capabilities§ 02
Four practices. One standard of judgement.
02
Special Situations
Support for complex, delayed, disputed, distressed, or reputationally sensitive situations where facts, stakeholders, and execution risk must be brought under control.
03
Recovery & Stabilisation
Programme recovery, post-acquisition stabilisation, interim leadership support, delivery planning, and stakeholder confidence rebuilding.
04
Private Assignments
Discreet assignments for private clients, family offices, boards, and investors requiring senior judgement, structured options, and executable recommendations.
When we are engaged§ 03
Mandates begin where certainty ends.
The common thread is not distress. It is complexity: incomplete facts, exposed capital, technical ambiguity, reputational risk, and decisions that cannot wait for a perfect information set.
- 01A high-value asset is delayed, disputed, or technically unclear
- 02An investor needs independent judgement before committing capital
- 03A board requires an executable recovery plan, not another slide deck
- 04A family office is assessing a maritime, aviation, or mobility opportunity
- 05A transaction depends on separating engineering fact from optimistic narrative
- 06A post-acquisition situation needs calm stabilisation and stakeholder control
Sectors§ 04
Onça Partners focuses on sectors where assets are technically complex, capital-intensive, reputationally sensitive, and unforgiving of poor judgement.
01
Maritime
Yacht builders, shipyards, marine technology, owner build rescue, electric and hybrid vessel platforms.
02
Aviation
MRO, propulsion, aerospace suppliers, advanced air mobility, modification and completion programmes.
03
Advanced Mobility
Electrification, autonomy, high-value engineered platforms, infrastructure-linked mobility ventures.
Approach§ 05
Clear facts. Senior judgement. Executable options.
- I
Diagnose
Rapidly establish the real technical, commercial, and stakeholder position.
- II
Structure
Convert complexity into decision-ready options, risks, and trade-offs.
- III
Stabilise
Support immediate actions to protect value, confidence, and momentum.
- IV
Execute
Assist through acquisition, recovery, transition, or board-level decision points.
Principles§ 06
Deliberately selective.
Principal attention
Senior judgement is the product. Engagements are kept selective by design.
Technical literacy
Engineering reality is treated as central to the commercial answer, not an appendix.
Discretion first
The work is structured for private clients, sensitive facts, and reputationally exposed decisions.
Who we work with§ 07
A selective client base.
- HNWI and UHNWI clients
- Family offices
- Private investors
- Lenders and creditors
- Boards and shareholders
- Niche maritime and aviation companies
- Legal and transaction advisers
- Owners of complex high-value assets
Model§ 08
Principal-led.
Network-enabled.

Engagement teams are assembled selectively around the mandate.
