A practical guide to people due diligence (HR / human capital DD) — how PE, search funds, and M&A buyers size key-person risk, leadership depth, compensation design, and retention before specialists run deep org diagnostics.
People due diligence answers a value-creation question: can this team execute the investment thesis after ownership changes — or will talent flight, key-person gaps, and misaligned incentives erase the model?
Buyers review leadership quality and bench depth, org design and spans of control, critical-role maps, compensation and equity design, benefits and contingent labor, culture and retention signals, employment claims, union/labor exposure, and HR systems that must scale post-close. Findings feed retention packages, management equity, 100-day org design, price chips, and go / no-go calls.
People diligence sits beside operational due diligence, legal due diligence, ESG due diligence, and financial due diligence. Ops DD tests process capacity; legal DD tests contracts and claims; financial DD tests payroll cost and liabilities; people DD tests whether humans can deliver the plan.
| Work product | Primary question | Typical owner | Output |
|---|---|---|---|
| People / HR DD | Can the team execute and stay? | HR diligence / org advisors | Org risk + retention plan |
| Operational DD | Do processes and capacity work? | Ops diligence | Capacity + process memo |
| Legal employment | What claims and contract liability? | Counsel | Claims + contract analysis |
| Financial DD | What is true people cost? | QoE / financial DD | Payroll bridge + benefits |
CEO/founder fit for the hold period, CFO/COO depth, functional leaders for GTM and product/ops, board effectiveness, and succession for every critical seat. Interview quality and reference patterns matter more than titles on a slide.
Who owns customer relationships, product IP in their heads, licenses, pricing authority, and supplier terms? Document concentration, single-threaded accounts, and whether knowledge is transferrable.
Headcount by function and geography, spans and layers, contractor vs FTE mix, remote/hybrid design, and whether the structure supports the growth or efficiency thesis.
Base/bonus/equity mix, commission plans, change-of-control treatment, unvested equity overhang, and whether incentives reward the behaviors the PE plan requires post-close.
Voluntary turnover, regrettable attrition, hiring funnel health, Glassdoor-style reputation, DEI signals where material to customers or regulation, and competitor poaching risk.
Open claims, wage-and-hour and misclassification exposure, I-9/work authorization, union/CBA status, handbook quality, HRIS maturity, performance management, and benefits liabilities.
| Stage | People focus | Depth |
|---|---|---|
| Pre-LOI screen | Public leadership history, sector talent pressure, obvious key-person flags | Light |
| LOI / exclusivity | Org chart, critical roles, high-level compensation, turnover snapshot | Medium |
| Confirmatory | Interviews, retention design, claims schedule, payroll sample, benefits | Deep |
| SPA / close | Employment reps, key employee agreements, 100-day org plan | Legal + ops |
| 100 days | Leadership changes, incentive refresh, culture interventions | Value creation |
| Approach | Typical cost | Timeline | Best for |
|---|---|---|---|
| Boutique HR / org firm | $15K–$100K+ | 1–3 weeks | Confirmatory on shortlist |
| Big Four people stream | $50K–$200K+ | 2–5 weeks | Large or multi-jurisdiction deals |
| Employment counsel deep dive | $10K–$75K+ | 1–3 weeks | Claims, CBA, misclassification |
| dodilligence first-pass pack | $49 ($39.20 w/ code) | Minutes | IC triage and shortlist screens |
Traditional people / org diligence often starts at $15,000–$100,000+. A structured public-info first-pass is $49 list — $39.20 with DI20-WELCOME.
| Signal | Severity | Why it matters |
|---|---|---|
| Founder is sole customer face + product authority | Deal-Killer | Thesis may die if founder exits |
| Material wage-and-hour / misclassification pattern | Deal-Killer | Cash liability + culture hit |
| Regrettable attrition >20% in critical functions | High | Retention packages may not stick |
| Commission plan overpays for low-quality revenue | High | Sales behavior fights PE plan |
| No HRIS / shadow spreadsheets for headcount | High | Integration and cost control fail |
| Open union organizing or CBA renewals mid-deal | High | Timeline and cost uncertainty |
| Glassdoor / employee signals of toxic leadership | Watch | Flight risk after announcement |
| Equity refresh cliff post-close not modeled | Watch | Hidden dilution or cash cost |
Specialists need payroll extracts, org charts, interview access, and counsel support. Before that budget unlocks, deal teams still need a structured screen: leadership history, public reputation signals, sector talent pressure, disclosed litigation, and whether growth claims depend on a few named individuals.
dodilligence delivers a public-information diligence pack that helps you prioritize which names justify $15K+ people / org specialist work. It is not an employment audit, culture survey, or legal opinion — it is a fast, consistent first-pass for IC triage and shortlist building.
It is the buy-side review of leadership, org design, incentives, culture, retention, and employment risk so deal pricing and integration plans reflect human capital reality.
Leadership bench, key roles, compensation, benefits, turnover, labor relations, claims, HR systems, and readiness to execute the thesis post-close.
Often 1–3 weeks for middle-market deals; longer with multi-country payroll, unions, or large contingent workforces.
Irreplaceable founders without succession, material undisclosed employment claims, systemic misclassification, and incentive designs that collapse under new ownership.
Ops DD covers processes and capacity; people DD covers the humans who run those processes and whether they stay after close.
Yes for light screening. Deep interviews and payroll audits usually require post-LOI access under NDA.
Concentration of revenue, knowledge, licenses, or customer trust in one or a few people — buyers map dependency and design retention before pricing.
Yes. Use it to triage which targets deserve full specialist HR budgets. Screening research is not an employment audit or legal advice.
