The behavioral due diligence framework for service M&A
Going beyond financials to assess the human elements that determine acquisition success
Why traditional due diligence misses the mark
Last year, I watched a well-funded PE firm acquire a profitable marketing agency after flawless financial due diligence. Six months later, 40% of clients had defected and half the creative team had quit. The spreadsheets showed a healthy business, but they missed the behavioral dynamics that actually drove performance.
Service companies aren't factories with predictable outputs. They're collections of relationships, cultural norms, and human dynamics that financial analysis can't capture. Here's the systematic framework we've developed to assess what really matters.
The three pillars of behavioral due diligence
1. People Assessment Framework
Leadership team evaluation beyond resumes
Management depth and succession readiness
Can the business operate for 6 months without the founder?
Who makes key client decisions when founders travel?
How do employees describe leadership team strengths/weaknesses?
What happens when senior people disagree on strategy?
Emotional intelligence indicators
How does leadership handle client complaints or crises?
Do managers give credit to teams publicly?
How are difficult conversations approached?
What's the pattern of employee feedback and response?
Team dynamics assessment
Cultural cohesion signals
Do people eat lunch together or separately?
How are after-hours social events received?
What stories do employees tell about company history?
How do different departments speak about each other?
Collaboration vs. competition patterns
Are wins celebrated individually or collectively?
How is cross-team knowledge sharing encouraged?
Do people help colleagues or protect their territories?
What happens when someone makes a mistake?
2. Client Relationship Analysis
Relationship depth evaluation
Personal vs. institutional connections
Which clients would follow key employees to competitors?
How many relationships exist at multiple organizational levels?
Do clients interact with junior staff or only seniors?
What percentage of communication happens outside formal channels?
Client dependency patterns
Who are the clients that require founder involvement?
Which relationships are truly transferable?
How do clients react to team changes historically?
What services are "nice to have" vs. "mission critical"?
Behavioral client signals
Loyalty indicators
Client tenure distribution (how many 5+ year relationships?)
Payment patterns (do good clients pay early?)
Referral frequency (unprompted recommendations)
Scope expansion over time (growing wallet share)
Warning signs
Constant price negotiations despite good service
High maintenance requirements relative to fees
Multiple vendor comparisons each contract renewal
Reluctance to integrate systems or processes
3. Cultural Sustainability Framework
Values alignment assessment
Stated vs. practiced values
Do company values show up in daily decision-making?
How are values-conflicts resolved in practice?
What behaviors get rewarded vs. what gets said?
How do hiring/firing decisions reflect stated culture?
Change adaptability indicators
How has company adapted to past challenges?
What's the response to new technology adoption?
How are process improvements typically received?
Do people fear change or embrace experimentation?
Cultural transfer risks
Integration complexity factors
How different are operating philosophies?
What practices would employees resist changing?
Which cultural elements are competitive advantages?
What changes would trigger talent flight?

Creating competitive advantage When competitors focus purely on financial metrics, behavioral due diligence becomes a differentiator. You identify and acquire businesses that not only have good numbers but can maintain performance through transition and growth.
Service companies succeed through people, relationships, and culture. The best acquirers understand these elements aren't just "soft factors"—they're the predictive indicators of future performance that financial analysis alone can't capture.
