Our take

In Germany, over 20 million properties are in poor energy conditions, resulting in the emission of 70 million tons of CO2 each year. Enter, formerly known as Baupal, is taking on this challenge by offering an online building application service that leverages digital processes to streamline the entire design, planning and permitting process.

Traditional energy assessments are too slow and can fail to meet climate goal demands. Enter offers a quick digital survey that provides a transparent assessment of the energy status of customers' buildings within minutes. This innovative approach enables Enter to provide efficient and effective energy assessments at scale, helping to accelerate progress towards a more sustainable future.

Since its founding in 2020, Enter has experienced remarkable growth and momentum. With successful funding rounds under its belt, the company is now equipped with significant capital to accelerate its vision of becoming Europe's leading provider of energy-efficient retrofitting solutions.
