The Problem: US-Based Tools Don't Work for European Companies

GDPR violations, excessive costs, and data sovereignty concerns

US Commercial Tools

  • Data stored on US servers (GDPR risk)
  • 3,000-18,000 EUR per year for 50 employees
  • Complex Data Processing Agreements
  • Schrems II compliance uncertainty
  • No EU data residency guarantees
  • Vendor lock-in with proprietary systems

Blik for EU Tech

  • Deploy on Hetzner, OVH, or your EU datacenter
  • Zero licensing fees, unlimited employees
  • No third-party data processing required
  • GDPR-compliant by architectural design
  • Complete control over data residency
  • Open source, audit and customize freely

Average Savings for EU Tech Scaleups

50-employee company: 2,400-17,400 EUR/year | 100-employee company: 5,000-35,000 EUR/year | 200-employee company: 10,000-70,000 EUR/year

GDPR Compliance by Design

Self-hosting means you control everything

EU Data Residency

Deploy on Hetzner (Germany), OVH (France), or any EU provider. All employee data stays within EU borders. No international data transfers required. Full GDPR Article 44-50 compliance.

No Third-Party Processing

Your infrastructure, your data. No Data Processing Agreements with US vendors. You are the data controller.

Right to Access & Deletion

Full database access for GDPR requests. Export employee data in machine-readable format. Delete personal data with one command. Complete audit trail for compliance documentation.

Privacy by Default

Reviewer anonymity built into architecture. Configurable data retention policies. Minimal data collection principles. Encrypted connections and secure token-based access.

Audit Ready

Open source means full transparency for auditors. Document data flows with included architecture diagrams. Track all administrator actions. Demonstrate technical and organizational measures.

Schrems II Compliant

No reliance on Standard Contractual Clauses. No US cloud providers in data path. EU-based deployment eliminates cross-border transfer concerns. Legal certainty for your compliance team.

Data Flow Architecture

Your EU Server (Hetzner/OVH) → PostgreSQL Database (EU) → Backup Storage (EU) → Admin Access (HTTPS) → Reviewer Tokens (No authentication required)

All data remains in EU jurisdiction at all times

Cost Analysis: Stop Paying US Vendors

Real numbers for European tech companies

Company Size Lattice Cost Culture Amp Cost Blik Hosted Blik Self-Host Max Savings
50 employees 18,000 EUR 21,000 EUR 588 EUR 600 EUR 20,400 EUR
100 employees 36,000 EUR 42,000 EUR 2,388 EUR 720 EUR 41,280 EUR
200 employees 72,000 EUR 84,000 EUR 2,388 EUR 960 EUR 83,040 EUR
500 employees 180,000 EUR 210,000 EUR Custom 1,440 EUR 208,560 EUR

Blik Hosted = €49/month (50 employees) or €199/month (200 employees). Self-host costs = EU VPS only (Hetzner: €50/month). No per-user fees. No licensing costs.

Technical Questions Answered

Which EU hosting providers are recommended?

Germany: Hetzner Cloud (excellent price/performance, 100% renewable energy, Nuremberg datacenter)

France: OVH Cloud (strong privacy reputation, Strasbourg/Roubaix datacenters)

Netherlands: TransIP (Dutch privacy laws)

Finland: UpCloud (Nordic data protection standards)

Any provider with EU datacenters works. Minimum specs: 2 vCPU, 4GB RAM, 40GB SSD.

What about email sending for invitations?

Use EU-based SMTP providers: Mailgun EU (Dublin datacenter), SendGrid EU, Amazon SES EU (Frankfurt), or your own mail server. Configure SMTP in the setup wizard. All email processing stays in EU. Templates are simple text, no tracking pixels.

Can we integrate with our existing LDAP/SSO?

Currently, admin authentication uses Django's built-in system. LDAP/SSO integration is on the roadmap. For now, admins log in with username/password. Reviewers never authenticate (token-based access only). You can modify the authentication backend since it's open source.

How do we demonstrate GDPR compliance to auditors?

Blik includes documentation showing:

1) Data flow diagrams proving EU residency
2) Technical measures (encryption, access controls, anonymity)
3) Organizational measures (admin audit logs, retention policies)
4) Data subject rights implementation (export, deletion)

Open source code allows auditors to verify technical controls directly. For GDPR compliance guidance, see GDPR.eu and European Data Protection Board.

What's the migration path from Lattice/Culture Amp?

Export your employee list from existing tool as CSV. Import into Blik via Django admin or API. Historical review data can be archived separately (Blik focuses on new cycles, not historical reporting). Plan 2-4 weeks for parallel running during transition period. Most teams switch completely after first successful cycle.

How do backups work with GDPR retention requirements?

PostgreSQL dumps to EU-based storage (Hetzner Storage Box, S3 EU buckets). Set automated retention policies matching your data retention requirements. Implement deletion scripts for GDPR "right to be forgotten" requests. All backup data stays in EU jurisdiction. Encrypted backups recommended for extra security.

Can we run this completely air-gapped behind our firewall?

Yes. Disable external AI API calls and use local models. Configure SMTP to your internal mail server. All web traffic stays internal. No outbound internet access required. Perfect for highly regulated environments or companies with strict security policies.
