Challenge

Sensitive data, strict requirements

As a service provider in the subsidy sector, Joulee works daily with sensitive customer data – from building assessments to property documents and income details. Using AI tools like ChatGPT was therefore not an option for data protection reasons.

GDPR requirements

Subsidy data contains personal information that must not be transferred to US servers.

High application volume

Over 3,500 subsidy applications require efficient processes while maintaining consistently high documentation quality.

Partner communication

Supporting over 350 craft businesses requires clear, professional, and fast communication.
