Why Top Investors Mandate VDRs
Successful investors move with speed and precision while mitigating risk. VDRs are the core technology that enables this.
Accelerated Due Diligence
A well-organized VDR allows legal, financial, and technical teams to conduct their reviews in parallel, drastically cutting down the time from term sheet to closing.
Ironclad Confidentiality
Protect sensitive financial data, intellectual property, and your own investment thesis. Granular permissions ensure that analysts, partners, and external counsel see only what they need to see.
A Defensible Audit Trail
Every single action—every view, download, and comment—is logged. This creates an immutable record for compliance and provides a clear history of the diligence process.
Actionable Engagement Analytics
See which documents your team or co-investors are focusing on. High engagement with the “Financials” folder or “IP Patents” can provide valuable intelligence on deal progress and areas of concern.
Streamlined Portfolio Management
Use a VDR as a central repository for collecting and reviewing quarterly reports, board materials, and key metrics from your portfolio companies.
Structuring Your Due Diligence Room
For maximum efficiency, structure your VDR with a clear, logical folder tree. A typical investor setup includes:
Corporate & Legal
Formation documents, cap table, minutes
Financials
Historical statements, financial model, projections
Product & Technology
Demos, technical architecture, IP/patents
Team & HR
Key employee agreements, org chart
Sales & Marketing
Go-to-market strategy, customer contracts, pipeline
Market & Competition
Market analysis, competitive landscape
