TL;DR: EIC Accelerator 2027 is the last round of the European Innovation Council's flagship startup fund under Horizon Europe, and its rules were adopted by the European Commission on 5 November 2026. It has €578 million: €428 million for the Open call (any technology) and €150 million for four Challenges. A single startup or SME can win a grant below €2.5 million (70% of costs), an equity investment from €1 million to €10 million, or both. Short proposals can go in at any time; full proposals have four 2027 batch dates: 20 January, 17 March, 1 September and 4 November.
