Due Diligence

For Investors, Acquirers and Founder-Led Businesses

For Investors, Acquirers and Founder-Led Businesses

Most deals don’t fail because of strategy.


They fail because risks surface too late.

At Alexander Rosse, we provide rigorous, commercially focused due-diligence services that help founders, investors and acquirers make informed decisions —and protect value.

We work on both sides of the transaction, giving us a clear view of what really matters.

Financial Due Diligence

We go beyond headline numbers to understand what is sustainable.

  • Quality of earnings and revenue analysis
  • Burn rate, runway and working-capital assessment
  • Review of historic performance and accounting robustness
  • Validation of forecasts and assumptions
  • Identification of funding gaps, hidden liabilities and red flags

Outcome: clarity on risk, not surprises post-investment.

Commercial & Market Due Diligence

Growth narratives are easy. Evidence is harder.

  • Assessment of product-market fit
  • Revenue concentration and customer dependency
  • Competitive positioning and barriers to entry
  • Stress-testing growth assumptions and scalability

Outcome: confidence that the story holds under scrutiny.

Operational & Systems Due Diligence

Operational weakness kills momentum after a deal.

  • Review of finance systems, reporting and data integrity
  • Assessment of scalability and internal controls
  • Identification of operational bottlenecks and integration risks

Outcome: realistic expectations of post-deal execution.

Tax, Regulatory & Structural Review

Poor structure erodes value — quietly but consistently.

  • Identification of historic and future tax exposures
  • Review of group structures and cross-border complexity
  • Regulatory and compliance risk assessment

Outcome: fewer deal blockers and reduced re-pricing risk.

Vendor (Pre-Sale) Due Diligence

Founders who prepare early protect valuation.

  • Identifying and resolving issues before buyers find them
  • Improving deal certainty and speed
  • Strengthening negotiating position

Outcome: cleaner deals, fewer last-minute concessions.

Who This Is For

  • VC and private-equity investors
  • Strategic acquirers
  • Founder-led tech businesses preparing for funding or exit
  • Scale-ups anticipating investor scrutiny in the next 6–24 months

Our View (and it’s a firm one)

Most founders underestimate diligence risk.


Most investors overestimate how “clean” early-stage businesses are.

Our job is to close that gap — early, clearly and commercially.

Common Due Diligence Issues in Founder-LedTech Businesses

What Investors Find — and What Founders Often Miss

By the time due diligence begins, it’s usually too late to “fix” fundamentals. At Alexander Rosse, we regularly support founders, investors and acquirers through diligence processes. Patterns emerge quickly. Most issues are not fatal — but they directly affect valuation, deal speed and negotiating power.

Below are the most common issues we see in founder-led and VC-backed businesses.

1. Forecasts That Don’t Survive Scrutiny

Forecasts are often:

  • Overly optimistic
  • Poorly linked to actual operating drivers
  • Missing downside or stress scenarios

Why this matters:
Investors don’t expect certainty — they expect realism. Weak forecasting erodes trust fast.

2. Burn Rate and Runway Not Clearly Controlled

Founders know the headline runway, but not:

  • How it changes under stress
  • Which costs are genuinely flexible
  • How long it would take to course-correct

Why this matters:
Unclear runway increases perceived risk and reduces valuation leverage.

3. Revenue Quality Issues

Common problems include:

  • Heavy customer concentration
  • One-off or non-repeatable revenue treated as recurring
  • Weak churn, retention or cohort analysis

Why this matters:
Revenue quality matters more than revenue size.

4. Weak Financial Reporting and Data Integrity

We often see:

  • Inconsistent management accounts
  • Poor reconciliation between systems
  • Heavy reliance on founder “explanations”

Why this matters:
Investors fund businesses — not founders’ memories.

5. Informal or Outdated Group Structures

Particularly common in fast-scaling tech businesses:

  • Historic structures that no longer make sense
  • IP ownership not clearly aligned
  • Cross-border complexity added without planning

Why this matters:
Structural uncertainty creates legal and tax risk — and slows deals.

6. Tax and Compliance Risks Left Untested

Founders often assume:

  • “We’ll deal with it later”
  • “It’s not material yet”

Why this matters:
Small issues compound under diligence and invite re-pricing.

Our View

Most diligence issues are fixable — if identified early.

The businesses that perform best in transactions are not the ones without issues, but the ones that:

  • Understand them
  • Quantify them
  • Address them proactively

This is what protects value.

Next Step

If you expect investor or acquirer scrutiny in the next 6–24 months, early review creates leverage.
