Press release from February 21st, 2025

Saxovent invests together with Vireo Ventures, FJ Labs and IBB Ventures in German reorganisation start-up

Berlin, February 21st, 2025 – Deutsche Sanierungsberatung (DSB), a nationwide energy consultancy and marketplace for refurbishment measures, has secured 3.6 million euros as part of a seed financing round. The investment round was led by Vireo Ventures from Berlin.

DSB was founded in 2024 by three former Enpal employees and advises and supports homeowners in the complete refurbishment of their property. It is based on a digital platform that can be used to plan extensive refurbishment measures, from insulation to solar panels. The company intends to use the fresh capital to further expand its platform, further automate services and grow faster.

A total of 16 million buildings in Germany need to be refurbished in order to achieve the energy class D prescribed by the EU by 2033. The hurdle to refurbishment is often a lack of trust in various providers – and this is exactly where we come in. As a neutral consultant and provider with local partners, we simplify the lives of millions of homeowners in order to reduce electricity and heating costs.

Sebastian Schmidt – Founder and CEO, DSB

The aim of the company is to make energy-efficient refurbishment using PV systems, heat pumps, insulation or window replacement as simple, affordable and transparent as possible. It wants to establish itself as a nationwide central partner that brings single-family homeowners and local tradespeople together.

The energy-efficient refurbishment of residential buildings is a key lever for climate protection – and it must be as simple as possible for owners. This is precisely where Deutsche Sanierungsberatung comes in by creating transparency and removing barriers. Our focus is on supporting companies that are driving real change with innovative business models. The DSB brings the right players together and makes it easier for homeowners to access efficient and sustainable refurbishment.
