Tips
- Read the cited current official page before applying because program dates and terms are volatile.
- State fit with the documented stage, geography, and attendance model; do not rely on an aggregator's old terms.
- Ask for the complete investment, fee, and follow-on documents when the public page does not publish them.

Two or more founders, UK/EU registration, planned €1M–€3M raise, and ideally TRL 6–7; no acceptance rate published.
