The technology section of a data room is one of the most frequently under-prepared areas in a sale process. Management teams focus on financial and commercial materials; the technology section is often assembled quickly, inconsistently, and without a clear sense of what buyers actually need.
A well-structured technology data room does several things:
- Reduces the volume of ad hoc requests from buyers and their advisers
- Demonstrates operational maturity: a management team that can document its platform clearly is one that understands it
- Accelerates the due diligence timeline
- Frames the technology story before buyers form their own conclusions
What to include
1. Architecture documentation
What buyers want: a clear, current description of how the platform is built, not a historical document or a diagram last updated three years ago.
Minimum required:
- System architecture diagram (current state)
- Infrastructure overview: cloud providers, hosting model, key services used
- Data flow diagram for key processes
- Integration map: third-party APIs, data feeds, and system dependencies
- Any significant architectural decisions and the rationale (ADRs are useful here)
Common mistake: providing an architecture document that reflects how the system was designed, not how it currently operates. Discrepancies between documentation and reality are a red flag.
2. Security documentation
What buyers want: evidence of a security programme, not assertions about security posture.
Minimum required:
- Security policy summary (or full policy)
- Certifications held: ISO 27001, SOC 2, Cyber Essentials, PCI DSS (if applicable)
- Penetration test reports (most recent, with evidence of remediation)
- GDPR / data protection documentation: DPA, privacy policy, data retention policies
- List of any security incidents in the past 24 months, and the actions taken
Common mistake: omitting security documentation entirely, or providing only a privacy policy. Buyers will ask for it; having it ready reduces delay and demonstrates maturity.
3. Technical debt register
What buyers want: a specific, honest account of the technical debt, not a vague acknowledgement.
Minimum required:
- A prioritised list of the most material technical debt items
- For each: what it is, why it exists, what the remediation cost/effort is, and what the risk is of not addressing it
- Evidence of any debt addressed in the past 12 months
Common mistake: either omitting technical debt documentation entirely (buyers will find it anyway) or providing an exhaustive list with no prioritisation (which reads as unmanaged).
4. Engineering team documentation
What buyers want: a clear picture of the team structure, capabilities, and key-person risk.
Minimum required:
- Engineering org chart with roles and tenure
- Key technical roles: CTO/VP Engineering, tech leads, principal engineers, with brief bios
- Team distribution: locations, contractors vs. employees, any offshore or nearshore teams
- Attrition data for the past 24 months
- Any known planned departures or retention arrangements
5. Product and roadmap
What buyers want: evidence that the product roadmap is credible and that the team can deliver.
Minimum required:
- Current product roadmap (12–18 months)
- Recent delivery history: what was shipped in the past 12 months vs. what was planned
- Key metrics: release cadence, deployment frequency, incident/outage frequency
- Competitive positioning summary
6. AI and data
For businesses with AI components or significant data assets:
- Description of AI features and their role in the product
- Model infrastructure: proprietary, fine-tuned, or API-based, with relevant cost and dependency information
- Data governance summary: how data is collected, stored, processed, and deleted
- Any relevant regulatory documentation (sector-specific AI regulations, data localisation requirements)
How to organise the data room
Structure the technology section to mirror how buyers will conduct their assessment:
- Architecture and infrastructure (what is built)
- Security and compliance (how it is protected)
- Engineering team and process (who built it and how)
- Product and roadmap (where it is going)
- AI and data (if applicable)
Label everything clearly. Include a brief description of each folder’s contents. Buyers and their advisers will navigate the data room with limited context, so make it easy.
What to do if documentation doesn’t exist
Commission a Technology Health Check before the process starts. The output includes the documentation, framing, and findings that form the backbone of a strong technology data room, and identifies the gaps that need to be addressed before buyers see them.
A Proof Edge Technology Health Check is specifically designed for this preparation. The report structure maps directly to the data room structure above. Where the Health Check is followed by a Sell-Side Technology Report, the report itself can be included in the VDD pack.
