In the heart of Europe’s green revolution, a German startup is making waves in the home energy efficiency market. Enter, formerly known as Baupal, is not just another player in the retrofitting game – it’s changing the rules entirely.
A €19.4 Million Vote of Confidence
Enter has secured a whopping €19.4 million in Series A funding. This round, led by Target Global, saw participation from heavyweight investors including Coatue, Foundamental, A/O Proptech, and Partech. But what’s driving this level of investment?
A Story of Bootstrapped Success
While they have secured significant funding, their journey began with impressive bootstrapping. As Patric Hellerman, Founding Partner and GP at Foundamental, notes:
“Enter was already net profitable. So the company had more or less bootstrapped with very, like we’re talking 100,000 bucks of family and friends money that they had used to become that profitable.”
This testament to Enter’s efficient business model and market fit helps explain why investors are now so eager to back their expansion.
Enter helps homeowners make smart choices for energy-efficient homes.
The Magic of Data: Enter’s Unique Approach
Enter’s secret weapon is its innovative use of data. Here’s how it works:
- Digital Survey: Homeowners answer just 8-9 questions.
- AI Analysis: Enter’s system processes these answers into 250 data points.
- Accurate Assessment: This method achieves 90% accuracy in identifying energy-saving potential.
- On-Site Verification: Energy consultants visit to verify and gather more data.
- Digital Twin: Homeowners receive a virtual replica of their building.
This process provides a clear roadmap for improving energy efficiency, all starting from a simple questionnaire.
Bridging a Critical Gap
Germany faces a significant challenge:
- Current renovation rate: 200,000 properties per year
- Required rate to meet climate goals: Over 1 million properties annually
Traditional methods simply can’t keep up. Enter’s streamlined process aims to bridge this massive gap.
More Than Just Assessments
Enter goes beyond energy assessments:
- Handles subsidy applications for renovations
- Offers financing options
- Facilitates contractor bidding process
This comprehensive approach makes energy-efficient upgrades more accessible and affordable for homeowners.
Patric highlights the importance of Enter’s approach:
“The energy audit is the right to play in this market because you acquire the physical substance and you gain the trust of the customer because you’re a credible arbitrator.”
This insight underscores how Enter’s detailed assessments are key to building trust and driving action in the retrofit market.

From the Founders’ Perspective
Justus Menten, Enter’s co-founder and managing director, emphasises the need for efficiency: “Currently, around 200,000 properties are renovated in Germany each year. However, to meet our climate goals, we need to renovate more than one million properties.”
Co-founder Max Schroeren adds, “We gather 250 data points and only ask eight to nine questions. This provides us with 90% accuracy regarding the real energy-saving potential of the house.
The Challenge Ahead
The task Enter faces is monumental. Millions of buildings need upgrading, and traditional methods are falling short. But with their data-driven approach and strong financial backing, Enter is well-positioned to make a significant impact.
