Germany's Energy Efficiency Tech sector is what this directory maps — 357 companies, $911M in disclosed funding, ranked by equity raised and recent momentum. No unicorns yet, but the capital stack is real and it's moving.
Tado° leads with $212M, which is a different category entirely from the rest of the field. Metiundo sits at $47M, Paul at $44M, and then it drops fast — kiutra at $19M, Etalytics at $18M, SPiNE at $5M. So the funding curve here is steep and the gap between the top name and everyone else is wide. Median install growth across energy apps is running at roughly +28% YoY, which tells you demand-side interest is real even when disclosed funding is thin. Hot themes driving deal flow right now: EV battery technology, next-generation EV platforms, solar electricity generation. Investors staying active include HTGF, Europa, Future Energy Ventures, EIC Fund, and BitStone Capital. I'd watch that EV-adjacent cluster closely this quarter. If you're mapping where German efficiency tech is actually concentrating, the answer isn't evenly distributed — it's pooling fast around a handful of funded platforms while dozens of smaller bets wait for their Series A moment.
