Operational Due Diligence
& Integration

We assess whether a business can sustain its performance under new ownership. Then we help make sure it does. We work with private equity firms, family offices, M&A advisors, and search fund operators.

The Gap in Every Deal

Three Lenses. Only One Looks Under the Bonnet.

Financial Due Diligence

What does the business earn?

Validates historical earnings, normalises financials, and assesses the quality of reported revenue and profit. Answers what the business is worth today.

Legal Due Diligence

What are the contractual risks?

Reviews contracts, litigation exposure, regulatory compliance, and intellectual property. Protects the price you pay and informs the purchase agreement.

Operational Due Diligence

Can this business actually deliver on the investment thesis once it changes hands?

ODD goes to the engine of the business. It tests whether the operation is genuinely robust or held together by the knowledge, relationships, and workarounds of a few key people. It examines the systems, governance, processes, and dependencies that determine whether a company can function, scale, and transition under new ownership.

People

Where is knowledge concentrated? What happens when key individuals leave?

Systems

Are operations documented and supported by real infrastructure, or patched together?

Governance

Can the business withstand scrutiny from regulators, auditors, and investors?

"Operational due diligence shifts the lens from due diligence to lose, to due diligence to win."

What We Assess

Five operational dimensions that determine whether a business can sustain its performance through a transaction and beyond.

The ODD Scope Checklist

10 operational questions every investor should answer before closing. A practical framework for scoping what matters.

We'll occasionally share relevant case studies. No spam. No newsletters.

Why Diadem

Three things that define how we work and why clients choose us.

Bespoke to the Deal Thesis

Every assessment is designed around the specific transaction, the specific buyer, and the specific value creation plan. We do not apply a generic checklist. The scope, depth, and focus of our work is shaped by what the investor needs to know.

Continuity from Assessment to Execution

We assess operational risks before the deal closes, then implement the integration roadmap after. The same senior team carries the engagement through. No handover gap. No lost momentum.

Forward-Looking, Not Just Risk-Focused

We identify the operational changes that will accelerate value creation under new ownership. Our findings inform a practical action plan. The question is not just what could go wrong, but what needs to happen next.

Sector Experience

Universal Methodology. Sector-Informed Judgement.

Financial Services

Retirement funds, asset management, insurance, and fintech. Governance-intensive environments where regulatory compliance, fiduciary duty, and systems integrity directly determine deal viability.

Food and Agribusiness

Agriprocessing, agricultural inputs, and agtech. Operationally complex sectors with seasonal dynamics, commodity exposure, supply chain fragility, and regulatory requirements that demand practical assessment.

Manufacturing and Distribution

Consumer products, FMCG, and supply chain operations. Capital-intensive businesses where margin sustainability, systems maturity, and operational scalability are central to the investment thesis.

Our assessment methodology also supports transactions in professional services, technology, healthcare, and other sectors where operational complexity is a factor.
