Company Overview

meinhaus.digital was established in 2023 and operates from Stuttgart, offering an AI-powered platform for planning residential energy renovations [Startup.eu]. The company's legal structure involves Palasts GmbH, which operates the meinhaus.digital platform [meinhaus-digital.com, 2026]. Leonie Dowling and Aleksandra Kudaeva are listed as Managing Directors of Palasts GmbH, while Carolin Marie Krebber and Ina Schroeder are identified as Managing Directors of meinhaus.digital [5, 2026; 9, 2026].

The company secured a pre-seed round reported at 1 million euros (approximately $1.1 million) in 2023, with participation from L-Bank Baden-Württemberg [fundable.ai, Startup.eu].

Data Accuracy: YELLOW -- Core details are corroborated by multiple sources, but some leadership roles and the exact funding date rely on single-source reporting.

The Product and the Stack

The core proposition is a software layer that translates a homeowner's renovation goals into a structured plan. The platform is an AI-supported tool that delivers a full renovation plan, including architectural concepts, detailed cost breakdowns, and bank-ready financing documents, within three business days [7, 2026]. The service combines this software with human expertise, integrating architect and energy consulting know-how [Startup.eu]. Public-facing specialties include energetic retrofits, process and design consulting, and the creation of a digital twin [LinkedIn - meinhaus.digital].

Data Accuracy: YELLOW -- Core product claims are consistent across multiple sources, but technical specifications and live customer deployment details are not publicly available.

The Market They Are Entering

The German residential energy renovation market is driven by regulatory deadlines, public subsidies, and aging housing stock. The broader German renovation and modernization market for residential buildings exceeds €100 billion annually [BDH, 2025]. The primary tailwind is the Building Energy Act (GEG), which sets efficiency standards for existing buildings.

Metric	Value
Total Renovation Market (DE)	100 €B
Energy Retrofit Segment	35 €B (estimated)

Data Accuracy: YELLOW -- Market sizing is inferred from analogous industry reports and government funding announcements.

The Competitive Field

Meinhaus.digital operates in a fragmented market against established offline service providers and adjacent software platforms. Its core promise is to simplify architectural planning and cost estimation for residential energy retrofits, a process traditionally dominated by independent architects, energy consultants, and general contractors. The company's AI-powered platform aims to compress a weeks-long, multi-vendor coordination effort into a streamlined digital workflow [7, 2026].

Data Accuracy: YELLOW -- Competitive analysis is based on market structure inference; no direct competitor data was provided in structured sources.

Opportunity

meinhaus.digital is positioned to capture a share of the planning and advisory spend that precedes every retrofit. The core opportunity is to become the default digital architect for residential energy renovations in Germany. The company's platform aims to compress a fragmented, months-long planning process into a streamlined digital workflow delivered in days [7, 2026].

Data Accuracy: YELLOW -- The opportunity framing relies on logical extrapolation from cited product claims and market context.
