Due diligence fails quietly when red flags sit in separate PDFs — a director here, a lawsuit there, a related party nobody put on the same page. Checklists confirm documents arrived; they do not show that the target's 'independent' supplier shares a PSC with the seller's spouse. Analysts paste registry extracts into memos that executives skim. By the time a relationship surfaces in integration, the warranty clock has already started. linkchart makes due diligence relationship maps tangible: companies, persons, addresses, events and items linked by owns, supplies, litigates with and guarantees. Deal teams interrogate structure visually before they argue valuation.
Why a real link chart for due diligence
Most people start this work with tools that were never designed for networks. Documents narrate. Spreadsheets tabulate. Whiteboards photograph poorly and refuse to scale. A dedicated due diligence relationship map approach treats every person, place, asset and event as a node — and every meaningful connection as an edge you can label, question and revise.
That shift matters because decisions in due diligence are rarely about a single record. They are about patterns: who introduces whom, which address keeps appearing, which phone bridges two clusters, which event changed the shape of the network. linkchart exists so those patterns stay visible while you work, not only in the final slide.
Deal teams hunting for a due diligence relationship map, related-party chart or counterparty network diagram need more than checklist software. linkchart.art visualises companies, people and risk events for clearer investment decisions.
Who this map is for
Diligence analysts, deal teams, and investigators checking counterparties, officers, and hidden related parties.
The signature move on the canvas: Hunt related-party triangles — shared officers, addresses, and counterparties — that financial statements alone will not confess.
What belongs on the map
Every due diligence relationship map gets noisy when the wrong things dominate the board. Prioritise these domain-specific anchors before decorative extras:
- Target company and subsidiaries
- Officers, controllers, and key staff
- Material counterparties and lenders
- Red-flag overlaps and PEP touches
Sample relationship labels
Prefer short, scannable edge text. Useful starters for this domain include: officer of, related party to, supplies, guarantees, shares address with, litigation with.
Your first week on this canvas
Map the target’s legal perimeter and named officers. Add the top counterparties from contracts or AP data. Midweek, chase shared addresses and repeated surnames into new company cards. Flag unresolved PEP or sanction adjacency. Deliver a one-screen related-party picture before exclusivity deepens. Document why each card earned its place so the due diligence board does not drift into decoration. Before the week closes, freeze a viewer link for one outsider and capture their first three questions as backlog edges or notes.
What not to do
Do not confuse a clean credit report with a clean relationship graph. Avoid infinite expansion into harmless minority investments. Never bury a conflict because the deal thesis is exciting. Resist outdated officer data from stale scrapes. If an edge cannot be explained in one plain sentence, it is not ready for a briefing view of your due diligence map. Quantity of nodes is not progress; disciplined omission is often the skill that keeps a due diligence relationship map trustworthy.
What success looks like
A diligence network surfaces conflicts and control surprises early enough to renegotiate or walk. IC memos cite specific edges, not vibes about “complex structure.” When someone new opens the due diligence canvas, they should grasp the live question, the strongest links, and the next check within minutes. That is the operational definition of a successful due diligence relationship map on linkchart.
How to use linkchart for due diligence
You do not need a special template to begin. Open the linkchart app, create a map, and build outward from the question you must answer. The workflow below is a proven path for people doing due diligence who want speed without losing structure.
- Name the map after the target and diligence workstream, with a clear as-of date in notes.
- Seed the target company, material subsidiaries and key counterparties.
- Add directors, PSCs and management persons with role edges.
- Link related-party customers, suppliers and property addresses that repeat.
- Attach litigation, regulatory and debt events that change risk posture.
- Deliver a viewer map into the data room conversation for focused Q&A.
As the map grows, resist the urge to make it decorative. Beauty comes from clarity: consistent card titles, honest labels, and notes that explain uncertainty. A slightly ugly accurate chart beats a pretty misleading one every time — especially when due diligence work has consequences.
Entity types that shine for this use case
linkchart supports investigation-ready cards you can reuse across domains. For due diligence, start with these and expand only when a new type earns its place on the canvas:
Company Person Address Event Phone Vehicle
Person and organisation cards carry identity. Addresses anchor geography. Phones and communication profiles expose bridges between clusters. Events give you time. Vehicles and items capture the physical world that due diligence narratives often depend on. Together they form a vocabulary you can teach a teammate in minutes.
Real-world scenarios
Related-party revenue concentration
Top customers look diversified by name. Company cards and person cards for directors reveal two buyers controlled by the seller's sibling through LLPs at one address. Event cards for contract renewals cluster just before the process launched. Quality of earnings discussions shift from margins to independence of demand — because the graph made the concentration undeniable. Investment committees walk related-party hops instead of trusting a checklist that only confirmed documents arrived.
Sanctions adjacency in a supplier
A critical component vendor sits two hops from a designated entity via a joint venture. Mapping companies, persons and historic shipment events clarifies whether exposure is theoretical or operational. Item cards for licences and end-user statements attach to those edges. Counsel and compliance stop debating vibes and debate a specific path. Sanctions and integrity questions attach to specific paths, which is what counsel can actually diligence. Cut-off dates keep mid-process discoveries from being mistaken for the original as-of picture.
Management integrity triangulation
Open-source hits mention a prior insolvency and a tribunal claim. Person cards link the CFO to both, with company cards for the failed venture and event cards for the judgment date. Vehicle and address lifestyle notes stay out of the map unless evidenced and relevant. The IC memo gains a relationship appendix that investment committee members can actually walk. Cut-off dates keep mid-process discoveries from being mistaken for the original as-of picture.
Across these scenarios the constant is the same: when due diligence information stays trapped in siloed files, people argue about memory. When it lives as a labelled network, people argue about evidence — which is exactly where productive work happens.
Field practices that keep maps trustworthy
- Keep allegation edges visually distinct from registry facts.
- Record information cut-off dates; diligence maps go stale mid-process.
- Cluster by risk theme — ownership, litigation, sanctions, cyber — for steering packs.
- Ask sellers to confirm or correct the graph; silence is informative.
Common pitfalls
- Do not treat absence of a link as proof of independence.
- Avoid drowning the canvas in immaterial micro-entities.
- Never paste full passport or bank scans into shared diligence maps.
Compared with slides, whiteboards and generic diagram tools
Slide software is excellent for presenting a finished argument and poor at hosting an evolving network. Whiteboards are wonderful for a one-hour workshop and hostile to long-running due diligence work. Generic diagrammers can draw boxes and arrows, yet they rarely treat investigative entities as structured records with fields your team actually fills in. linkchart sits in the gap: fast enough for a working session, structured enough for a case file, visual enough for a briefing.
FAQ: Due diligence
Is this a replacement for our VDR?
No. The VDR stores documents; linkchart explains how entities in those documents relate.
Can sell-side teams use it too?
Yes — preparing a clean ownership and related-party map reduces surprise in Q&A.
How granular should ownership be?
Deep enough to answer control and conflict questions; stop when edges no longer change decisions.
Useful after signing?
Absolutely for integration — the same graph becomes a day-one stakeholder and dependency map.

Ethics, privacy and good judgement
Any powerful mapping tool can be misused. For due diligence, draw a bright line between legitimate analysis and voyeurism. Collect only what you need. Share only with people who have a role. When working with personal data, follow the laws and policies that apply to your organisation or community. linkchart is a canvas — responsibility for what you place on it remains yours.
Especially when maps include minors, victims, or confidential sources, default to minimisation. Use initials, role titles or delayed identifiers when full names are unnecessary for the analytical task. A precise network with careful labelling beats a sensational wall of private detail.
