Who is Caelith built for?

German and Luxembourg fund administrators serving ManCos/AIFMs — one platform license covers all your ManCo clients. Closed-ended PE/RE structures are the core focus, though the engine also covers open-ended obligations such as Min-2 liquidity management tools.

What regulatory frameworks does Caelith cover?

AIFMD II, the Luxembourg 2013 AIFM Law, SIF/RAIF, MiFID II Annex II, ELTIF 2.0, SFDR and German KAGB. 13+ rules across 6 frameworks. Annex IV validated against ESMA XSD Rev 6 v1.2.

Does the AI copilot see our investor data?

No. The Compliance Copilot runs on a PII-anonymizing pipeline and is PII-safe by design — it never sees personal data. It drafts and flags, but never files autonomously; your second conducting officer approves before submit.

How does the audit trail work?

Every decision is stored as a block with a SHA-256 hash linked to the previous block, so any modification is detectable — tamper-detectable by design (an internal control; independent attestation is required for regulator-admissible evidence). One click exports a complete evidence bundle for CSSF, BaFin or auditor review.

When did AIFMD II take effect, and what about 2027?

AIFMD II has been in force since 16 April 2026. ESMA's harmonized XML template and updated RTS/ITS arrive by Q1 2027; Caelith validates against current national XSDs today and is built for the 2027 template, so data captured now carries forward.

Where is our data hosted, and how secure is it?

EU-hosted (Railway, Netherlands / EU-West), PostgreSQL 16 with row-level security and multi-tenant isolation, encryption in transit and at rest. DPIA and EU AI-Act FRIA completed, TOMs documented per Art 32 GDPR, ISO 27001 roadmap underway, SOC 2 controls-aligned, DPA-ready.

cut annex iv cycle time. keep the audit trail.

Caelith ingests your spreadsheet, admin-export and fund-document handoffs, maps them to the 180+ Annex IV fields that apply to your funds (of 340+ in the full schema), and validates with every exception cited to the regulation that flagged it. your second conducting officer approves before submit. the SHA-256 audit chain records every decision. live for CSSF (LU), BaFin (DE); 8-NCA roadmap.

§ 03 · design-partner field test

we build Caelith with our design partners — not for them.

each year we onboard a small cohort of LU & DE fund administrators and build against their real Annex IV cycles. partners get the engine at preferential terms and a direct line to the founder; we get the ground truth that keeps Caelith honest.

Annex IV prep per filing · 18 ManCo clients on one license · 0 XSD errors.

context

Annex IV prep spread across spreadsheets, admin exports and fund documents — ~3 weeks of manual assembly per cycle, evidence scattered across email and screenshots.

approach

we wired Caelith to their existing handoffs, mapped to the 180+ applicable fields (of 340+ in Annex IV), ran the rules engine with every exception cited, and produced a validated XML pack + tamper-detectable evidence bundle.

result

prep cycle 3 weeks → 2 days; one license covered all 18 ManCos; zero XSD errors; a regulator-facing audit chain per pack.

does a well-informed investor with €80K qualify for a RAIF?

not on the amount alone. under Art. 2 of the RAIF Law a well-informed investor must invest at least €100,000 — or hold a written assessment from a bank, investment firm or ManCo confirming the expertise for the investment. €80K by itself doesn't meet it.
