PE firms scrutinize financials, operations, and technology during diligence. Marketing — the function that drives the revenue they're paying for — gets a slide in the management presentation. The firms that make better returns evaluate marketing infrastructure before they write the check.
The Problem
Revenue growth masks marketing infrastructure problems
A company growing at 40% year-over-year looks great in a pitch deck. But that growth might depend entirely on one paid channel with deteriorating economics, a founder's personal network, or a customer concentration that makes future acquisition uncertain. Financial diligence validates revenue quality. Marketing diligence validates revenue sustainability — and most PE firms skip it entirely.
Post-acquisition growth plans assume marketing capabilities that don't exist
The value creation thesis for most PE deals assumes accelerated growth post-acquisition. But if the target company's marketing infrastructure can't support that acceleration — no attribution, no documented playbooks, no scalable acquisition channels — the growth plan fails in year one. By the time the operating team discovers the marketing gaps, they've lost 12-18 months and the value creation timeline is compressed.
Customer acquisition economics are misrepresented without marketing diligence
Companies present blended CAC numbers that obscure channel-level economics. The overall CAC looks healthy, but 60% of customers come from organic or referral channels with near-zero cost, while the paid channels needed for growth have unsustainable economics. Without marketing diligence that disaggregates acquisition economics by channel, PE firms overpay based on growth assumptions that paid marketing can't deliver.
How We Help
We conduct marketing due diligence for PE firms evaluating growth-stage companies. Our assessment evaluates five dimensions that determine whether a company's marketing can support the post-acquisition value creation plan.
Channel sustainability analysis disaggregates customer acquisition by channel, evaluating cost trends, competitive dynamics, and scalability. We identify which channels are producing sustainable growth and which are producing growth that will deteriorate — concentration risk that financial diligence doesn't capture.
Marketing infrastructure assessment evaluates the systems, data, and processes that support growth. We review attribution accuracy, marketing automation maturity, CRM data quality, and the operational infrastructure needed to scale. Companies that grew on founder-led sales and word-of-mouth often lack the infrastructure to execute the paid, content, and partnership growth plans that PE value creation theses require.
Team capability evaluation assesses whether the marketing team can execute the post-acquisition growth plan. We evaluate leadership quality, team structure against growth requirements, and the gap between current capabilities and the value creation thesis. This assessment often reveals that the marketing team built for the company's current size can't support the growth the PE firm is paying for.
Competitive positioning analysis evaluates the company's brand strength, content assets, and market presence relative to competitors. Strong competitive positioning is a durable moat that supports premium pricing and customer retention. Weak positioning means the company is vulnerable to competitive disruption that could undermine growth projections.
Our deliverable is a marketing due diligence report that quantifies marketing risk, identifies capability gaps, and estimates the investment required to build marketing infrastructure capable of supporting the value creation plan. This report informs both deal valuation and 100-day post-acquisition planning.
What we deliver
- Channel sustainability report — disaggregated acquisition economics with scalability assessment
- Infrastructure assessment — marketing systems, data, and process maturity evaluation
- Team capability analysis — current vs. required marketing capabilities for value creation thesis
- Marketing investment estimate — budget and timeline to build required marketing infrastructure
PE firms that skip marketing due diligence pay premium multiples for companies with unsustainable growth engines. The firms that include marketing in diligence either negotiate better terms or avoid deals that would underperform — both of which protect returns.
Our Methodology
Our marketing due diligence methodology runs parallel to financial and operational diligence, typically completing within 3-4 weeks. Phase one (week 1) reviews available marketing data — acquisition reports, channel performance, customer data, and marketing technology stack documentation. We identify preliminary risk areas and develop the interview guide.
Phase two (weeks 2-3) conducts deep assessment — interviews with marketing leadership, channel-level economics analysis, infrastructure evaluation, and competitive positioning review. We validate management's marketing claims against actual data, identify discrepancies, and quantify marketing risk.
Phase three (week 4) produces the diligence report — quantified findings, risk assessment, capability gap analysis, and investment requirements for the value creation thesis. The report includes actionable recommendations for 100-day post-acquisition marketing priorities.
How We Work
Marketing due diligence engagements are compressed 3-4 week projects aligned to deal timelines. We work within your existing diligence process and coordinate with financial, operational, and technology diligence workstreams.
Week 1: data review and preliminary assessment. We review all available marketing materials, channel reports, and customer acquisition data. Initial risk areas are identified.
Weeks 2-3: deep assessment. Interviews with marketing leadership, channel-level analysis, infrastructure evaluation, and competitive review. We verify management claims against actual performance data.
Week 4: report delivery and discussion. The marketing diligence report includes quantified findings, risk ratings, and investment estimates. We present findings to the deal team and discuss implications for valuation and post-acquisition planning.
Post-close, we optionally extend into 100-day marketing transformation planning — translating diligence findings into the operational plan for building marketing infrastructure that supports the value creation thesis.
- Deal protection — marketing risk identified before closing, informing valuation and terms
- Value creation planning — accurate marketing investment estimates for post-acquisition growth
- Faster post-close execution — 100-day marketing plan based on diligence findings

Frequently asked questions
How much does marketing due diligence cost?
Marketing due diligence engagements range from $35K-$75K depending on company complexity and depth of assessment. This is a small fraction of deal value — and the cost of discovering marketing infrastructure problems post-close is typically orders of magnitude higher in both direct investment and lost value creation timeline.
How long does marketing due diligence take?
Standard marketing diligence completes in 3-4 weeks, running parallel to financial and operational diligence. Accelerated assessments for time-pressured deals can deliver preliminary findings in 2 weeks with full reports following. We align to your deal timeline.
What does marketing due diligence typically reveal?
Common findings include: channel concentration risk (over-dependence on one acquisition source), attribution inaccuracy (reported CAC doesn't match actual economics), infrastructure gaps (no marketing automation, poor CRM data, missing measurement), and team capability mismatches (team built for current scale, not post-acquisition growth plan). Most deals have at least two significant marketing risk factors.
What makes Winston Francois different from Big Four diligence providers?
Big Four firms evaluate marketing through a financial lens — reviewing spend allocation and reported metrics. We evaluate marketing as operators — assessing whether the growth engine actually works, whether it can scale, and what it would cost to build the infrastructure the value creation thesis requires. The difference is the depth of operational marketing knowledge applied to the assessment.
How does marketing diligence affect deal terms?
Marketing diligence findings typically impact deals in three ways: valuation adjustments based on growth sustainability concerns, earn-out structures that tie consideration to marketing-dependent growth targets, and post-close investment budgets for marketing infrastructure buildout. Some findings are deal-breakers; most inform negotiation and planning.
What type of PE firm should invest in marketing due diligence?
Firms with value creation theses that depend on revenue growth acceleration. If your plan is operational efficiency and cost optimization, marketing diligence is less critical. If you're paying growth multiples and planning to accelerate acquisition, marketing diligence should be standard practice. The deals where marketing diligence matters most are the ones where you're paying the most for future growth.
