    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."

    Assessment Framework

    What We Assess

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

    01

    Management and Key-Person Risk

    We identify where critical knowledge, relationships, and decision-making authority are concentrated in individuals rather than embedded in the organisation. Key-person dependency is the single most common source of post-deal operational failure.

    02

    Operating Systems and Infrastructure

    We evaluate system maturity, integration capability, data integrity, and whether existing technology can support the demands of integration, reporting, and growth. Inadequate systems delay integration and inflate post-deal costs.

    03

    Governance and Compliance

    We assess board structures, regulatory obligations, internal controls, and the governance frameworks that determine whether the business can withstand external scrutiny from regulators, auditors, and investors.

    04

    Commercial Sustainability

    We examine contract transferability, customer concentration, supplier dependency, margin drivers, and whether the commercial model can withstand ownership change without material revenue risk.

    05

    Integration Complexity

    We map the organisational structures, system dependencies, and cultural dynamics that will determine the speed, cost, and risk profile of post-acquisition integration.

    Engagement Model

    One Firm. Two Phases. Complete Continuity.

    From pre-deal assessment to post-deal execution, the same senior team carries the work through. No handover. No lost context.

    The team that identifies the risks is best placed to resolve them. This continuity is what separates assessment from impact.

    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.

    While our operational assessment framework applies universally, deep sector knowledge sharpens the quality of every finding and recommendation.

    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.

    Who We Work With

    We serve investors, acquirers, and their advisors across the mid-market transaction landscape. We also work directly with search fund operators and acquisition entrepreneurs preparing to step into founder-led businesses as first-time CEOs.

    Private Equity Firms

    Pre-deal operational assessment, post-close integration support, and portfolio company professionalisation.

    Family Offices and Private Investors

    Independent operational due diligence for direct investments, with hands-on integration leadership where required.

    Strategic and Corporate Acquirers

    Acquisition readiness evaluation, capability transfer planning, and operational integration execution.

    M&A Advisors and Corporate Finance Houses

    Specialist operational due diligence as part of broader advisory mandates, enhancing the quality and credibility of the deal process.

    Search Fund Operators

    Acquisition entrepreneurs and ETA (entrepreneurship through acquisition) searchers evaluating founder-led businesses for acquisition. We assess the operational risks that are specific to first-time CEOs stepping into businesses that have been built around a single individual.
