Where it is strong
- • More climate-tech investors, funds and corporate innovation teams than anywhere else in Europe
- • Utilities, infrastructure owners and regulators all within a day's meetings
- • English-first: contracts, hiring and compliance need no translation layer
Watch out for
- • Salaries and rent are the highest in the corridor — budget roughly double a Lisbon or Barcelona base
- • Attention is scarce: standing out needs proof, not just a deck
