Custodea Raises €350K Seed to Give European SMEs an EU-Hosted Data Lake

Custodea Secures €350K Seed Round

Custodea, an Amsterdam-based data-platform company operated by Custodea B.V., has raised €350,000 in Seed funding. The round was announced on 14 September 2026.

What Custodea Does

Custodea gives European SMEs a private, EU-hosted data lake for their business data. The platform uses read-only connectors to pull records from systems such as Exact Online, AFAS, Personio, DATEV and HubSpot into a continuously synchronised environment.

Businesses then read that data through tools like Power BI, Excel, Looker, Tableau and dbt, or feed it to their own AI agents.

Data Sovereignty as the Foundation

The company runs entirely on EU infrastructure with no US cloud sub-processors. Custodea positions data sovereignty as the foundation for making SMEs AI-ready.

Company Background

Custodea was founded in 2025 by Gregory Aerts. The company is headquartered in Amsterdam and operates under the legal entity Custodea B.V.

Why This Matters for the SME Data Market

European SMEs have increasingly moved core business functions into SaaS platforms — accounting, HR, CRM and ERP. That shift has created a fragmented data landscape in which records live across multiple vendors, each with its own access model and hosting region.

Custodea's approach is to consolidate those records into a single, continuously synchronised environment that remains within the EU. By using read-only connectors, the platform avoids writing back into source systems, which can simplify governance and reduce operational risk for the businesses that adopt it.

The emphasis on EU-only infrastructure and the absence of US cloud sub-processors addresses a specific concern among European buyers: where their data is stored, which legal regimes can reach it, and which third parties are involved in processing it. For SMEs preparing to adopt AI tooling, that sovereignty question often sits alongside more familiar requirements such as data quality and access control.

The AI-Readiness Angle

Custodea frames its data lake as a prerequisite for AI adoption rather than an end in itself. The pitch is straightforward: AI agents and analytics tools are only as useful as the data they can reach, and for many SMEs that data is scattered across disconnected SaaS systems.

By centralising records and exposing them through established analytics tools — Power BI, Excel, Looker, Tableau and dbt — Custodea aims to meet SMEs where they already work, rather than requiring them to adopt an entirely new analytics stack. Feeding the same environment to in-house AI agents extends that model to newer workloads.

What the Seed Round Signals

A €350,000 Seed round is a modest but meaningful step for a company founded in 2025. It suggests an early-stage build focused on establishing the connector library, the synchronisation layer and the EU-hosted infrastructure that underpin the product.

For observers tracking the European data-platform space, Custodea sits at the intersection of two durable trends: the consolidation of SME business data out of fragmented SaaS estates, and the demand for EU-resident infrastructure as a condition of adoption. The company's explicit positioning around data sovereignty makes that second trend a core part of its identity rather than a compliance footnote.

Summary

Custodea, founded in 2025 by Gregory Aerts and based in Amsterdam, has raised €350,000 in Seed funding. The company provides European SMEs with a private, EU-hosted data lake that synchronises records from Exact Online, AFAS, Personio, DATEV and HubSpot, and makes them available through Power BI, Excel, Looker, Tableau and dbt, or to in-house AI agents. It runs entirely on EU infrastructure with no US cloud sub-processors.
