FAQ
Frequently asked questions
Can you connect Salesforce to our ERP or legacy system?
Yes. We connect Salesforce via REST and SOQL to existing ERPs like Navision and to your cloud, so data is maintained only once. We already run an integration like this in live operation.
Do you host exclusively in the EU?
By default we host in Germany or the EU at Hetzner, depending on your needs and requirements: GDPR-compliant, without any US cloud requirement. If your setup needs Azure, we run it in the EU region with a data processing agreement.
Do you work remotely across DACH and Luxembourg?
Yes, and beyond. Our focus is on Germany, Austria, Switzerland and Luxembourg. In German and English we work remotely for clients across the entire EU.
Why Keycloak instead of Auth0 or Okta?
Keycloak is open source, maintained by Red Hat, and runs on your or our EU infrastructure with no per-user licensing. You get SSO, MFA and OAuth2/OIDC without locking yourself into a US vendor or paying more with every new user.
Is OpenDesk worth it instead of Microsoft 365?
If data sovereignty matters to you: yes. OpenDesk bundles Nextcloud, Element, Jitsi and OpenProject into the workplace Germany's public administration runs in production. We operate it in your branding on EU servers.
Are two people enough for my project?
Yes, from startup MVP to enterprise project. We work on every project as a pair with shared code access, so there is no single point of failure. We only take on projects we can fully deliver, and we hand over so you stay independent.
