1. The Legal Difference
Controller: decides why and how personal data is processed.
Processor: processes data on instruction of a controller.
2. How Startups Should Classify Themselves
Startups are controllers when:
- setting retention rules
- deciding analytics tools
- choosing tech stack
- determining data purposes
Startups are processors when:
- managing client data in their product
- running services strictly under client instructions
3. Examples for SaaS & Web3
- CRM – Controller
- Analytics tool – Processor
- Blockchain KYC vendor – Processor
- Marketplace – Controller
4. Mixed Roles
Many platforms have dual roles:
e.g., SaaS workspace tools = controller for employees, processor for customers.
Conclusion
Correct classification is not optional — it's fundamental to GDPR architecture.
