Key Insight<\/th>\nExplanation<\/th>\n<\/tr>\n<\/thead>\n
SIRENE is France’s official business registry<\/strong><\/td>\nMaintained by INSEE, it records every registered French company and establishment with legal, geographic, and sector data \u2014 free to access.<\/td>\n<\/tr>\n
SIREN vs. SIRET identifiers<\/strong><\/td>\nA SIREN number (9 digits) identifies a company; a SIRET number (14 digits) identifies a specific establishment. Both are essential for accurate prospecting.<\/td>\n<\/tr>\n
Raw data is not a pipeline<\/strong><\/td>\nSIRENE gives you company records, not decision-maker contacts or intent signals. Enrichment and qualification are required before any outreach.<\/td>\n<\/tr>\n
GDPR compliance is non-negotiable<\/strong><\/td>\nUsing SIRENE data for outreach triggers GDPR obligations. B2B use of professional data is permissible under legitimate interest, but documentation is required.<\/td>\n<\/tr>\n
Enrichment multiplies SIRENE’s value<\/strong><\/td>\nLayering SIRENE records with contact data, technographic signals, and intent data from additional sources turns a registry into a real prospecting engine.<\/td>\n<\/tr>\n
Warm introductions outperform cold outreach 20:1<\/strong><\/td>\nEven the best SIRENE-sourced list converts at under 2% via cold email. Platforms that deliver double opt-in introductions consistently<\/a> hit 40-50% reply rates.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
