DecisionOS is a decision infrastructure platform for enterprise technology buying. It turns fragmented evaluations — spreadsheets, slide decks, vendor calls, Slack threads — into one structured workflow that produces a board-ready, audit-ready decision memo. DecisionOS is built by nexalign GmbH in Berlin and hosted entirely in the European Union.

Who DecisionOS is built for

Primary users are CISOs and CIOs running high-stakes technology decisions under regulatory pressure — EDR/XDR, IAM, governance tooling, sovereign cloud, IT outsourcing, ERP/CRM. Secondary users are procurement, risk, legal and finance functions that sit inside buying committees.

What DecisionOS does

You describe the decision in plain language. DecisionOS extracts category, trigger, urgency and stakeholders.

You confirm options and a shortlist, select the compliance frameworks that apply (NIS2, DORA, ISO 27001, SOC 2), identify stakeholders with stance and key drivers, and score options against weighted criteria.

The output is a board-ready decision memo, per-role stakeholder briefs, a weighted vendor comparison matrix and a live Readiness Score that tells you when the memo is actually audit-ready.

What DecisionOS is explicitly not

Not a vendor directory, not a procurement marketplace, not a generic AI chatbot, not an RFP-automation tool, not a consulting firm. DecisionOS is purpose-built software for running a single technology decision end-to-end with structure, evidence and stakeholder alignment.

Why not just use ChatGPT?

General-purpose AI assistants are great for research. They do not keep a structured decision record, do not weight criteria, do not separate hard dealbreakers from trade-offs, and do not produce an audit-ready memo. DecisionOS wraps AI research inside a workflow that enforces structure, flags unverified data and persists everything across decisions with versioning and readiness tracking.

Hosting and privacy

DecisionOS is hosted entirely in the EU (Hetzner, Nuremberg). No third-party trackers, self-hosted analytics, no cookies. nexalign GmbH is a German company and operates DecisionOS under GDPR. A data-processing agreement with the hosting provider per Art. 28 GDPR is in place.
