Due Diligence

Full Definition

Due diligence involves a comprehensive appraisal of a business, individual, or opportunity, aimed at reducing risk and ensuring informed decisions. It includes financial analysis, legal verification, operational assessment, market evaluation, and team background checks.

In hiring or developer marketplaces, due diligence might involve verifying:

• Legal incorporation and contractor status
  
• Past project delivery and code samples
  
• References and feedback from previous clients
  
• Communication fluency and timezone compatibility
  

In investor contexts, it includes auditing financials, checking IP ownership, assessing market claims, and vetting founders. The depth and focus of due diligence can vary based on the size, type, and stakes of the deal.

Use Cases

• Hiring remote developers — Verifying skill claims, past clients, and legal compliance before onboarding.
  
• Startup investment — Investors perform legal and financial due diligence before issuing a term sheet.
  
• M&A — Acquiring companies assess legal liabilities, contracts, tech stacks, and culture fit.
  
• Partnerships — Agencies or platforms verify potential collaborators' credibility, stability, and alignment.
  
• Enterprise sales — Procurement teams evaluate compliance, risk, and financials before signing long-term SaaS deals.

Frameworks

• CDD vs EDD — Customer Due Diligence is standard vetting; Enhanced Due Diligence is for high-risk or large-volume relationships.
• KYC (Know Your Customer) — Especially for fintechs, marketplaces, or platforms onboarding users or contractors. Identity verification, financial records, sanctions lists.
• OCEG's GRC Framework — Governance, Risk, Compliance guidelines for due diligence across operations.
• FCPA Checklist — For U.S. companies: screening vendors and foreign entities against corruption compliance standards.
• Five-Pillar Compliance Approach — 1) Internal controls, 2) Independent testing, 3) Designated officer, 4) Employee training, 5) Customer due diligence.
• SOC 2 Type II + ISO 27001 — Security certifications that require due diligence in vendor management and third-party integrations.

Common Mistakes

• Overlooking cultural or geopolitical risk — Especially important in cross-border partnerships.
• Too shallow checks — Name and ID aren’t enough. Financial health, reputation, and digital footprint matter.
• One-time diligence — Treating it as a static event, not a recurring process.
• Ignoring beneficial ownership — True owners may be hidden behind legal structures.
• No documentation trail — Regulatory or audit issues later when diligence isn’t recorded properly.

Etymology

"Due diligence" originates from the Latin diligentia, meaning carefulness or attentiveness. It gained legal prominence in the 1930s through U.S. securities law, requiring brokers to disclose all material facts about an investment. In modern business, it refers to any systematic investigation prior to entering into an agreement.
