Impact Hub Bucharest and main partner Rompetrol, with the support of Climate-KIC, announce the 25 startups selected for Romania ClimAccelerator, the accelerator for green startups. The 25 selected startups fall into two categories: 10 in the Pre-Seed Stage, early teams developing a validatable idea; and 15 in the Seed Stage, companies that already have a prototype tested and validated with customers.
"We believe that innovative solutions developed by startups can deliver concrete, positive impact in areas such as renewable energy, circular economy or urban mobility. By getting involved in this programme, we aim to encourage and support new generations of entrepreneurs who are building the future in a responsible and sustainable way," said Costinela Drăgan, Group Sustainability & CSR Director, Rompetrol.
The programme supports the development of green startups proposing innovative solutions in areas such as urban mobility, renewable energy, climate-smart agriculture, sustainable cities, circular economy, reduction of industrial emissions, environmental education and responsible consumption.
