What does Sellsy do?
Sellsy is french crm, invoicing and marketing platform for smes — an alternative to hubspot and sage. It is listed under crm, fintech, and saas on EU Alts because its core functionality serves teams looking for a European crm tool with EU data residency, typically as a switch away from Salesforce and HubSpot.
Is Sellsy a good European crm alternative?
Sellsy is a fit for European businesses evaluating crm 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 and saas use cases.
Is Sellsy GDPR compliant?
Sellsy is headquartered in La Rochelle, France and falls under EU jurisdiction, so it likely 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). EU Alts has not yet independently verified Sellsy's ownership structure or hosting location, so we can't yet confirm its exposure to the US CLOUD Act the way we can for verified entries.
How do teams switch from Salesforce to Sellsy?
Most teams considering a move from Salesforce and HubSpot to Sellsy are drawn to its EU headquarters and crm workflow fit. EU Alts hasn't yet verified Sellsy's ownership and hosting facts, so treat any CLOUD Act or Schrems II conclusions as provisional until verification is complete. Plan a migration in stages regardless: export your data from the US incumbent, pilot Sellsy with a small team, then move the rest once integration coverage is confirmed.
