Commercial Due Diligence (CDD)

Commercial due diligence is the assessment of a company's market position, revenue quality, customer base, and go-to-market execution capability — conducted before an acquisition to determine whether the business can sustain and grow its revenue under new ownership.

Financial diligence tells you what happened. Commercial diligence tells you whether it will keep happening.

What CDD Covers

A comprehensive commercial diligence engagement typically examines five dimensions:

Market attractiveness — is the company operating in a market that is growing, stable, or contracting? What's the TAM, and does the company's bottoms-up analysis hold up against third-party data?

Competitive positioning — where does the company sit relative to alternatives? What is the switching cost for customers? Is the competitive moat real or is it just incumbent advantage that erodes under pressure?

Customer quality — how concentrated is revenue? Are customers growing or contracting? What does retention look like by cohort, not in aggregate? Are there relationships that exist only because of a single founder or executive?

Sales and GTM execution — does the company have a scalable sales process, or is revenue the result of founder relationships and individual heroics? Can the current team execute the growth plan, or does the plan require capabilities the organization doesn't have?

Revenue durability — is revenue recurring, contractual, and expanding? Or is it one-time, project-based, or dependent on annual re-wins with no contractual protection?

CDD vs Financial Due Diligence

These are complementary, not substitutes. A company can have perfectly accurate financials (clean QoE) and a fundamentally broken commercial engine — a customer base that is churning, a sales team that can't sell without the founder, or a market that is about to be disrupted. The QoE won't tell you any of that.

The GTM Dimension

Traditional commercial diligence from strategy consultancies (L.E.K., Bain, McKinsey) focuses heavily on market sizing, competitive dynamics, and customer research. This is valuable, but it often misses the operational layer — the question of whether the company's go-to-market machinery actually works.

GTM-focused commercial diligence adds:

• Pipeline analysis — not just coverage ratios, but stage-by-stage conversion rates, pipeline age, and source quality
• Sales team capability — quota attainment distribution, ramp time, founder dependency metrics
• CRM and data infrastructure — is the data trustworthy? Can the company actually produce the reports the growth plan requires?
• Process maturity — does a documented, followed sales process exist? Or is the "process" whatever each rep decides to do?

This operational lens is what separates GTM diligence from traditional CDD. A company can look commercially attractive from the outside (strong market, defensible position, good customer references) while being operationally fragile on the inside (no process, bad data, founder-dependent sales).

When CDD Goes Wrong

The most expensive CDD failures aren't wrong conclusions — they're missing dimensions. Common gaps:

• CDD validates the market thesis but never interviews churned customers
• CDD confirms customer satisfaction but never examines whether the sales team can acquire new logos without the founder
• CDD projects growth but never assesses whether the CRM data can support the pipeline analysis the growth projection requires
• CDD scopes down to "a few customer calls" to save time, then misses concentration risk because the sample was too small
