What is Caelex
Caelex is the regulatory operating system for the orbital economy.
It is a Berlin-based compliance platform that satellite operators, launch providers, ground-segment operators, and space-sector law firms use to navigate the EU Space Act, the NIS2 Directive, and national space laws across 10+ European jurisdictions. Caelex GmbH was founded in 2025.
What Caelex ships
Comply →
The regulatory command center. A web-based compliance workspace covering 15+ modules — authorization, registration, cybersecurity, debris, environmental, insurance, NIS2, COPUOS/IADC, export control (ITAR/EAR/EU Dual-Use), spectrum/ITU, UK Space Industry Act, US regulatory (FCC/FAA), digital twin, evidence — with AI-assisted document generation via the Astra copilot.
Atlas →
A searchable space-law database built for law firms. UN treaties, EU instruments, and national legislation across 10+ jurisdictions, deep-linked to official primary sources, with firm-wide shared annotations and AI-assisted research. Sales-assisted onboarding via a free 30-minute intro call.
Sentinel →
Autonomous compliance-evidence agents deployed at operator premises. Cryptographically signed hash chains, tamper-evident audit trails, cross-verification against public orbital data.
Ephemeris →
Forward-looking compliance risk engine. Each satellite is a digital twin; the engine forecasts compliance trajectories across the mission lifecycle — orbital decay, fuel depletion, subsystem degradation — against regulatory deadlines.
Verity →
Zero-knowledge compliance attestation. Ed25519-signed cryptographic proofs that demonstrate regulatory adherence to auditors, insurers, or counterparties without revealing the underlying operational data.
Who Caelex is for
Caelex is architected for operators of any size, from pre-seed startups preparing their first authorization to established primes with complex multi-jurisdiction portfolios.

How Caelex compares
vs. external compliance consultants
Consultants bill per engagement and deliver static deliverables. Caelex is a live system: the compliance state updates continuously as regulations change, as missions progress, as operator assets change. Consultants remain valuable for high-judgment legal opinions — Caelex complements them rather than replaces them.
vs. spreadsheet-based tracking
The spreadsheet is the most common compliance tool at pre-Series-A operators. It breaks down as soon as multiple regulations, multiple jurisdictions, and multiple mission phases have to be reconciled — which is the point at which Caelex starts to make sense.
vs. internal wiki tools (Notion, Confluence)
Internal wiki tools document compliance; they don't execute the compliance logic. Caelex runs the engine — given operator inputs it deterministically derives applicable articles, required evidence, and missing documents.
vs. generic enterprise compliance suites
Generic compliance platforms have no space-specific engines. They can track tasks and audit trails but cannot tell an operator 'this new satellite at this constellation tier now triggers EU Space Act Art. 55 and SatDSiG licensing.' Caelex does exactly that, with jurisdiction-specific rules baked in.
Frequently asked questions
What is Caelex?
Caelex is a regulatory compliance platform for the orbital economy. It helps satellite operators, launch providers, and space service companies assess and maintain compliance with the EU Space Act, the NIS2 Directive, and national space laws across 10+ European jurisdictions. Caelex is headquartered in Berlin and was founded in 2025.
What does Caelex do?
Caelex runs 15+ compliance modules inside a single workspace: authorization, registration, cybersecurity, debris mitigation, environmental, insurance, NIS2, COPUOS/IADC, export control, spectrum/ITU, UK Space Industry Act, US regulatory (FCC/FAA), digital-twin forecasting, and audit-evidence management. Given an operator's profile (operator type, jurisdiction, mission phase), the platform deterministically derives applicable articles, generates authorization documents, and tracks evidence.
Who is Caelex for?
Caelex is built for satellite operators (GEO, LEO, Earth observation, communications, navigation), launch providers, ground-segment operators, in-orbit service providers, space data providers, constellation operators, space-resource operators, and — via the separate Atlas product — space-sector law firms and in-house counsel.
What products does Caelex offer?
Five products: Comply (the compliance workspace), Atlas (a searchable space-law database for law firms), Sentinel (autonomous evidence-collection agents), Ephemeris (forward-looking compliance forecasting), and Verity (zero-knowledge compliance attestation). Comply and Atlas are the two primary user-facing products; the others support specific advanced use cases.
What jurisdictions does Caelex cover?
Caelex has deep national-law coverage for Germany, France, Luxembourg, the United Kingdom, Italy, the Netherlands, Belgium, Spain, Norway, Sweden, Finland, Denmark, Austria, Switzerland, Portugal, Ireland, Greece, Czech Republic, Poland, Estonia, Romania, Hungary, Slovenia, Latvia, Lithuania, Slovakia, Croatia, Turkey, Iceland, Liechtenstein, plus the United States and New Zealand. EU instruments and UN space treaties are covered as transnational layers that cross-reference into each jurisdiction.
Is Caelex the same as Atlas?
No. Atlas is a separate Caelex product — a searchable space-law database built for law firms, with deep-linked primary-source references and firm-wide shared annotations. Comply is the compliance workspace for space operators. Both products are made by the same company (Caelex GmbH, Berlin) and share security and AI infrastructure but serve different user bases.
How does Caelex compare to a compliance consultant?
Consultants bill per engagement and deliver static deliverables; Caelex is a live system that updates continuously as regulations change, as missions progress, and as operator assets change. Consultants remain valuable for high-judgment legal opinions. Caelex complements them rather than replacing them — think of Caelex as the system of record and the consultant as the senior counsel on specific escalations.
Does Caelex support the EU Space Act?
Yes — the EU Space Act (COM(2025) 335) is a core regulatory framework in Caelex. The platform maps all 119 articles of the proposed regulation, distinguishes the standard and light regimes, tracks operator classification (satellite operator, launch provider, constellation, ground segment, data provider, in-orbit services, space resource operator), and generates authorization dossiers aligned with the draft text.
Does Caelex handle NIS2 compliance for space operators?
Yes. Caelex includes an auto-classification engine that determines whether a space operator is an Essential or Important entity under the NIS2 Directive (EU 2022/2555), mirrors the 51 NIS2 requirements against the operator's current controls, and supports the 24h/72h/1-month incident-reporting workflow. National transpositions (German BSIG, French Loi Résilience, etc.) are tracked per jurisdiction.
Is there a free tier?
Yes — the free compliance assessment at caelex.eu/assessment returns a regulatory profile across the EU Space Act, NIS2, and 10+ national jurisdictions without requiring a credit card. Paid subscription tiers unlock the full compliance workspace, the AI copilot, document generation, and continuous monitoring.
Where is Caelex based?
Caelex is a GmbH headquartered in Berlin, Germany, founded in 2025. The team serves customers across the European Union, the United Kingdom, the United States, and New Zealand.
