Harvest Big: sovereignty score and 8 European alternatives

Big is the wealth-planning software from Harvest France for professionals in wealth management and financial advice. It is delivered as SaaS over the internet and brings the main wealth topics (tax, social security, succession, business-owner questions) together in one tool. Advisers use it to produce global or thematic wealth studies, simulate the effect of their recommendations and deliver personalised client reports. According to the vendor, the content is updated regularly and automatically.

Harvest France SAS has its registered office in Paris and belongs to the Harvest group, which also includes Quantalys, Feefty, Fincite and Firstance. The website names no parent company. According to its data protection charter, the personal data it processes is not transferred outside the European Union. The party that hosts the Big platform is not named. For European advisory firms this points to processing within the EU. Document the hosting party and any subcontractors in the data processing agreement.

Why digital sovereignty matters with Harvest Big

Harvest Big is headquartered in France and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Harvest Big scores best on data residency.

Harvest Big 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 Harvest Big together with your other vendors and gives a total score, a heatmap and the main risk drivers.
