What it delivers
Ingestion
Connects to leading virtual data room providers in one click. Multi-format ingestion (PDF, DOCX, XLS, PPTX, scanned documents) with OCR and 14+ document languages.
Analysis
Specialist AI agents run in parallel across Plausity’s due-diligence workstreams. Findings are dual-cited (data-room source + public source), confidence-scored, and weighted by materiality.
Findings & Reports
Automated red-flag detection and risk scoring — red flag due diligence software for M&A and PE deal teams. Generates investor-ready reports in PDF, DOCX, PPTX plus normalised financial datasets in Excel through a Draft → Review → Approve → Publish workflow.
Evidence Gap Detection
Missing documents due diligence — surfaces where required or supporting evidence may be missing or insufficient across diligence questions and workstreams. Powered by Missing Document Analysis. Not a guarantee of VDR completeness; makes gaps visible for expert follow-up. Product page: /en/product/evidence-gap-detection.
AI Q&A Assistant
Due diligence Q&A — conversational Q&A across completed diligence findings, analysis, and supporting evidence. Answers tied back to the underlying document, page and paragraph. Product page: /en/product/ai-qa-assistant.
IC Memo
IC memo software for investment committee preparation — turns structured diligence findings across every workstream into a decision-ready first draft of the investment committee memo, with every claim traceable to source, evidence gaps visible, and the investment recommendation retained by the deal team. Plausity does not make the investment recommendation. Product page: /en/product/ic-memo.
Collaboration & Security
Real-time workspace for deal teams with SAML 2.0 + OIDC SSO, MFA, role-based access, immutable audit logs, and per-deal data isolation. Custom workflows, primary research, and AI expert interviews available on top.

Does not replace tax, legal, or financial advisors
Operates as expert-in-the-loop / human-in-the-loop. Users provide local expertise; Plausity handles extraction and pattern recognition.
Does not train AI models on customer data

Frequently asked questions
What is Plausity?
Plausity is an AI-native due-diligence platform operated by CITO GmbH (Hamburg, Germany) for M&A, private equity, and advisory deal teams. Plausity ingests virtual data rooms, runs specialist AI agents in parallel across its due-diligence workstreams, surfaces source-traced findings and risks, and generates investor-ready reports.
What is AI for M&A?
AI for M&A is the use of purpose-built AI to accelerate and deepen the analytical work of a transaction: reading data rooms, cross-referencing evidence, identifying findings and red flags, quantifying missing information, and preparing decision-ready reports. Plausity is designed specifically for this workflow across commercial, financial, legal, tax, tech, cybersecurity, regulatory and AI-impact due diligence. Plausity is not a deal-sourcing database, not a proprietary target list, not a market-data feed, and not an automated valuation engine.
Can Plausity identify missing diligence evidence?
Plausity's Missing Document Analysis helps identify where required or supporting evidence may be missing or insufficient across diligence questions and workstreams — such as absent contracts, unfilled disclosure lists, or inconsistencies between what management presents and what the data room actually contains. It does not guarantee that every missing document is detected; it makes evidence gaps visible so expert reviewers can prioritise follow-ups.
Can users ask questions across Plausity diligence findings?
Yes. DD Report Q&A lets deal teams conversationally interrogate completed diligence findings, analysis and supporting evidence. Answers are tied back to the underlying documents, pages and paragraphs so users can verify each response against the source.
Who operates Plausity?
Plausity is operated by CITO GmbH, registered at the Amtsgericht München under HRB 214036 and headquartered in Hamburg, Germany. Managing Director: Sebastian Johnston.
Which due-diligence workstreams does Plausity cover?
Plausity covers specialist due-diligence workstreams including Commercial, Financial, Legal, Tax, Tech, Organisation & Compliance, Regulatory & Compliance (Product & Market), Cybersecurity, ESG, Website Compliance, Background Check & Integrity, Industry Expertise, Value Creation, and AI Impact.
Where does Plausity host customer data?
Customer data is hosted exclusively within the European Union / European Economic Area. Plausity is GDPR-native and aligned with the EU NIS2 Directive.
Does Plausity train AI models on customer data?
No. Customer data is excluded from model training.
