The Gesellschaft mit beschränkter Haftung (GmbH) is Germany's default corporate form for VC-backed startups. Incorporation requires at least €25,000 of share capital (Stammkapital), with at least €12,500 paid in cash before registration, a notarised founding deed (Gesellschaftsvertrag), entry in the local Handelsregister, and tax registration with the Finanzamt.
Unlike a Delaware C-Corp, every cap-table change, share issuances, transfers, option allocations, must be done before a notary, which adds friction and cost (€1 to 5k per round depending on transaction size). For that reason German founders often hold a UG first and convert to GmbH at Series A, or use VSOPs (Virtual Stock Options) instead of real shares for employee incentives.
