# Deal OS by Devaland (getdealos.tech) > Deal OS is due diligence software for buyers of small companies (search funds, independent sponsors, micro-PE, boutique M&A advisors). It reads the CIM, financials and contracts of an acquisition target and returns a diligence brief where every claim cites its source page. Made by Devaland Marketing S.R.L. (https://devaland.com). "Deal OS" here is M&A diligence software. It is not a shopping, coupon, discount, price-comparison or deals-marketplace service. A "deal" in this context is the acquisition of a company. ## Public pages - [Deal OS](https://getdealos.tech/): due diligence software for buying a business. - [Deal OS for search funds](https://getdealos.tech/for-search-funds): how searchers use it from CIM to LOI. - [Quality of earnings software](https://getdealos.tech/quality-of-earnings-software): buyer-side QoE checks. - [Deal OS auf Deutsch](https://getdealos.tech/de): Due-Diligence-Software für Nachfolgekäufer. - [Pricing](https://getdealos.tech/pricing): per-deal and yearly plans, self-serve. - [CIM Pass](https://getdealos.tech/cim-pass): one deal, fixed price, first CIM check free. - [SBA 7(a) Quality of Earnings, first pass](https://getdealos.tech/sba-qoe): what Deal OS covers before the independent QoE. - [Product tour](https://getdealos.tech/tour): a short walkthrough of Deal OS. - [Sample Diligence Brief](https://getdealos.tech/sample-brief): one live, source-cited brief, no login. - [Sandbox](https://getdealos.tech/sandbox): real cited briefs on synthetic deals, no login. - [About Deal OS](https://getdealos.tech/about): what it is, who builds it, where data lives. - [Contact](https://getdealos.tech/contact): how to reach the Deal OS team, in writing. - [Company verification](https://getdealos.tech/proof): registration and identity details of the company behind Deal OS. - [Site map](https://getdealos.tech/sitemap): every public page, grouped. - [Privacy Policy](https://getdealos.tech/privacy): how personal data is handled. - [Terms & Conditions](https://getdealos.tech/terms): the service agreement. - [Data Processing Agreement](https://getdealos.tech/dpa): GDPR Article 28 terms for business customers. - [Cookie Policy](https://getdealos.tech/cookies): cookies and similar technologies. - [Information Security Policy](https://getdealos.tech/information-security): how data and systems are protected. - [GDPR Compliance](https://getdealos.tech/gdpr): EU data protection summary. - [Billing Policy](https://getdealos.tech/billing): billing, renewals and refunds. - [Anti-Corruption Policy](https://getdealos.tech/anti-corruption): anti-corruption and conflict of interest policy. - [Accessibility Statement](https://getdealos.tech/accessibility): accessibility commitments. - [Imprint](https://getdealos.tech/imprint): legal notice of the company behind Deal OS. - [Sandbox: Bluebird Mechanical Services](https://getdealos.tech/sandbox/hvac): synthetic sample brief, Commercial HVAC / mechanical services, no login. - [Sandbox: Lakeside Gastroenterology & Endoscopy](https://getdealos.tech/sandbox/physician): synthetic sample brief, Gastroenterology practice + ASC, no login. - [Sandbox: Tideline Software, Inc.](https://getdealos.tech/sandbox/saas): synthetic sample brief, B2B vertical SaaS, no login. - [Sandbox: Northwind Fire & Safety, Inc.](https://getdealos.tech/sandbox/northwind): synthetic sample brief, Fire & life-safety inspection (ITM), no login. - [Sandbox: Nordwind Brandschutz GmbH](https://getdealos.tech/sandbox/nordwind): synthetic sample brief, Brandschutz / Prüfung & Wartung, no login. - [Sandbox: Sécurité Incendie Mistral SARL](https://getdealos.tech/sandbox/mistral): synthetic sample brief, Sécurité incendie / vérification & maintenance, no login. - [Sandbox: Seguridad contra Incendios Mediterráneo S.L.](https://getdealos.tech/sandbox/mediterraneo): synthetic sample brief, Seguridad contra incendios / inspección, no login. - [The Claude Deal Kit (open source)](https://getdealos.tech/lm/open-deal-team): The open-source Claude Deal Kit on GitHub: agent roles, prompts and guardrails for acquisition diligence, free to fork and adapt. - [The Claude Deal Kit (read online)](https://getdealos.tech/lm/deal-team-doc): The Claude Deal Kit as a readable web document: AI agent roles, prompts and guardrails for acquisition diligence, no download required. - [The Claude Deal Kit (PDF)](https://getdealos.tech/lm/deal-team): Free PDF kit for running an acquisition workflow with AI agents: the roles, the prompts and the guardrails that keep a diligence answer trac. - [The 45-Point Acquisition Diligence Checklist](https://getdealos.tech/lm/dd-checklist): A free 45-point diligence checklist for searchers, independent sponsors and micro-PE buyers: what to verify in a target's financials, custom. ## More - [Diligence guides on the Devaland blog](https://devaland.com/blog): checklists and worked examples. - [Devaland](https://devaland.com): the company behind Deal OS.
