What is Sumeria?
Sumeria (formerly Lydia) is a French mobile banking and payments app founded in 2011 by two French engineers.

What does Sumeria do?
Sumeria is french mobile bank with peer-to-peer payments and savings — formerly lydia. It is listed under banking and fintech on EU Alts because its core functionality serves teams looking for a European banking tool with EU data residency, typically as a switch away from well-known US incumbents.
Is Sumeria a good European banking alternative?
Sumeria is a fit for European businesses evaluating banking options where data residency and GDPR alignment matter — typical buyers include EU-based SaaS teams, public-sector projects, regulated industries (healthcare, finance, legal), and any organisation that needs to demonstrate that customer data does not leave the EU. It also overlaps with fintech use cases.
Is Sumeria GDPR compliant?
Sumeria is headquartered in Paris, France and falls under EU jurisdiction, so it processes user data under the GDPR by default. Customer data processing is supervised by France's data protection authority, the Commission nationale de l'informatique et des libertés (CNIL). Because the company is not US-incorporated, it is not subject to the US CLOUD Act — meaning US authorities cannot compel Sumeria to disclose customer data the way they can with well-known US incumbents. For European buyers, that often simplifies DPIA paperwork and standard contractual clauses.
How do teams switch from well-known US incumbents to Sumeria?
Most teams move to Sumeria from well-known US incumbents because they want EU data residency without giving up the core banking workflow. Sumeria's France base means a single jurisdiction for both the company and (typically) its hosting infrastructure, so you can drop Schrems II transfer impact assessments for this part of your stack. Plan the migration in stages: export your data from the US incumbent, pilot Sumeria with a small team, then move the rest once the integration coverage you need is confirmed.
Where is Sumeria based?
