Mercury: sovereignty score and 8 European alternatives

Mercury is a US fintech company with a banking platform for startups and small and mid-sized businesses. Its offering includes business checking and savings accounts, credit cards and spend management, payments and invoicing, integrations with accounting software, managed investment products for surplus cash, loans and an API; Mercury also has an AI-based accounting product and a separate personal offering. Mercury states that it is not an FDIC-insured bank: banking services run through partner banks, including Choice Financial Group and Column N.A. The service is delivered through the web and mobile apps.

In April 2026 Mercury received conditional approval from the US regulator OCC to establish its own national bank, Mercury Bank, N.A., to be headquartered in Utah; final approvals from bodies including the FDIC and the Federal Reserve are still required. As a US company Mercury falls under US jurisdiction, including the CLOUD Act. The software is proprietary and available only as a managed service. For European organisations Mercury is mainly a reference point from the US market.

Why digital sovereignty matters with Mercury

Mercury is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Mercury hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Mercury is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Mercury together with your other vendors and gives a total score, a heatmap and the main risk drivers.
