TL;DR: EU grants for small businesses exist, but almost none pay for day-to-day running costs. What a small company can realistically get falls into five groups: refunds of IP fees through the SME Fund, regional grants co-financed by the European Regional Development Fund, free expert services (Enterprise Europe Network, European Digital Innovation Hubs), bank loans guaranteed under InvestEU, and project grants for innovation (cascade funding calls, Eurostars, the EIC Accelerator).
