TL;DR: InvestEU is not a grant you apply for in Brussels. It is an EU budget guarantee (first set at €26.2 billion, later increased by €2.9 billion) that lets banks lend to riskier small companies and lets venture capital funds raise bigger rounds. A startup gets InvestEU money by asking a bank, a national promotional bank or a fund that has an InvestEU agreement. Guarantees cover up to 80% of a loan, and the banks and funds can still sign up until 30 June 2027. Below: a "which door" decision tree, a bank question script, a lender checklist, a deadline calendar and a worked example.
