GDPR Compliance for Startups: The No-BS 2026 Guide

GDPR doesn't have to cost €50k in legal fees. But ignoring it can cost you €20M or 4% of revenue. Here's exactly what you need at each stage of your startup — and what you can skip.

GDPR Requirements by Startup Stage

Stage	Must Have	Nice to Have	Skip for Now
Pre-revenue (0-10 customers)	Privacy Policy, Cookie Banner, Lawful Basis	DPA Template	DPO, SOC 2, External Audit
Early (10-100 customers)	All above + DPA, Data Processing Records	Security Documentation	DPO (unless required), ISO 27001
Growth (100+ customers)	All above + DPO (if required), Breach Process	SOC 2 Type I, Penetration Tests	Nothing — get serious
Scale (Enterprise sales)	All above + SOC 2, ISO 27001, Legal Team	Cyber Insurance	You need everything now
