M&A due diligence that surfaces
what deals hide

Deals move fast. Technical debt, security gaps, overstated digital capability, and weak code quality are easy to miss under time pressure. We deliver clear technical and digital diligence so you can negotiate, price risk, and plan integration with confidence.

In M&A, the quality of technology, code, security, and digital operations can materially affect valuation, integration cost, and post-close risk. Yet many deals rely on management presentations and high-level summaries rather than hands-on technical review.

Addbox supports buyers, sellers, and advisers with practical due diligence across engineering, security, marketing, and AI readiness. We go beyond slide decks with code reviews, vulnerability scans, architecture assessment, and findings your deal team can actually use.

Sound familiar?

This use case is for you if digital and technical risk needs clearer visibility before close.

  • Limited insight into code quality, architecture, and technical debt
  • Security posture unknown or based on self-reported claims
  • Marketing and growth metrics that are hard to validate independently
  • AI capabilities described vaguely with little evidence behind them
  • Tight timelines that make thorough technical review feel impossible
  • Integration risks that could become expensive surprises after the deal

Who this is for

Buy-side teams

You need independent technical diligence to validate claims, uncover risk, and inform valuation and integration planning.

Sell-side advisers and founders

You want to identify issues early, prepare credible responses, and reduce friction during buyer review.

Corporate development and investors

You need concise, decision-ready reporting across technology, security, and digital performance under deal timelines.

What we assess

Scope is tailored to the deal, but our diligence typically covers the areas where risk and value are most often hidden.

  • Code reviews across key repositories, patterns, maintainability, and delivery practices
  • Automated security scans and vulnerability assessment across applications and infrastructure
  • Manual review of architecture, integrations, APIs, and third-party dependencies
  • Cloud, hosting, access controls, backup, and operational resilience
  • Data handling, privacy exposure, and compliance gaps relevant to the transaction
  • Technical debt, scalability constraints, and cost-to-fix estimates where possible
  • Marketing channel performance, attribution claims, and digital growth quality
  • AI maturity, automation claims, model usage, and data readiness
  • Frontier-model-assisted analysis to surface issues traditional scans may miss

We combine automated tooling with senior human review so findings are prioritised by business impact, not just scan output volume.

The process

Structured for deal timelines. Clear outputs at each stage so your team can act quickly.

  1. Scope

    We align on deal objectives, access requirements, materiality thresholds, and the technical, security, and digital areas most relevant to the transaction.

  2. Review

    We conduct code reviews, architecture assessment, marketing and digital analysis, and documentation review based on agreed access and priorities.

  3. Scan and test

    We run security scans, vulnerability testing, and targeted technical checks against live systems, repositories, and integrations where permitted.

  4. Report

    We deliver concise findings for investment committees, legal teams, and integration planners with severity, evidence, and recommended next steps.

  5. Advise

    We highlight red flags, remediation priorities, and deal implications so you can negotiate terms, plan integration, and reduce post-close risk.

Outcomes you can expect

Diligence should lead to better decisions, not just more documents.

  • Clarity

    An independent view of technical reality

    Clear assessment of code quality, architecture, security, and digital performance beyond management narratives.

  • Risk

    Issues surfaced before close

    Vulnerabilities, technical debt, and operational gaps identified through code review, scans, and expert analysis while you can still act on them.

  • Negotiation

    Better-informed deal terms

    Evidence-backed findings that support pricing adjustments, warranties, remediation plans, and integration budgeting.

  • Integration

    A clearer post-close roadmap

    Prioritised remediation and integration guidance so the first 100 days are planned with eyes open.

Why Addbox

We are not a generic checklist firm. Our team has built, scaled, secured, and exited technology businesses, which means we know what good and bad looks like in real engineering and digital environments.

  • Hands-on code reviews by engineers who have shipped production systems
  • Security scans combined with frontier-model-assisted vulnerability analysis
  • Coverage across development, security, marketing, and AI in one team
  • Experience with platforms at scale, complex integrations, and legacy codebases
  • Reporting designed for deal teams, not just technical audiences
  • Ability to support remediation and integration after diligence if required
