GrünDach
Marketplace connecting flat-roof owners with vetted rooftop-greening installers, subsidies included.
The pitch
The problem
Cities subsidize green roofs heavily — Berlin pays up to €60/m² — but owners don't know the programs exist, and finding a qualified installer means calling ten companies for three quotes.
The idea
Enter your address, we estimate roof suitability from open aerial data, calculate available subsidies automatically, and match you with vetted installers who bid on the job.
Why now
Subsidy budgets are going unspent while climate targets tighten. The aerial imagery and subsidy databases are open data — they've just never been joined.
