What It Is

einhundert is a Germany-based provider of low-carbon energy solutions for the real estate and housing sectors. Its core goal is to help residential property portfolios reduce CO₂ emissions while giving tenants more stable and transparent energy costs. The official website emphasizes “Alles aus einer Hand” — an end-to-end offering covering photovoltaics, heat pumps, battery storage, and charging infrastructure. Strictly based on the site content, this is not a general-purpose SaaS product in the traditional sense, but rather an industry-specific solution combining energy infrastructure with digital tenant services.

Core Features and Software Capabilities

The disclosed products include 100.Strom, 100.Wärme, and 100.Kombi. 100.Strom provides low-carbon electricity for landlords and tenants; 100.Wärme focuses on reliable, price-stable low-carbon heating; and 100.Kombi combines photovoltaics with heat pumps to improve efficiency and reduce long-term costs. The part that comes closest to SaaS is the “tenant portal”: tenants can view electricity usage updated every 15 minutes, see their current monthly costs, and ultimately pay based on actual consumption. This can help housing cooperatives and property operators improve transparency around energy consumption. However, the website does not describe back-office administration, role-based permissions, reporting, ticketing, APIs, or third-party system integrations.

Pricing and Business Model

The public materials do not disclose plans, implementation fees, subscription fees, or contract terms, so it is not possible to assess the competitiveness of its software pricing. What can be confirmed is that einhundert emphasizes fair, stable, lower or competitive energy costs for tenants, avoids the traditional prepayment model, and settles bills based on actual usage. For buyers, the actual cost is likely tied to project scale, roof conditions, heating setup, and energy contracts, so direct consultation is required.

Pros and Cons

Its strengths are a clear industry focus and a strong fit for the energy-transition pain points of residential assets. It covers photovoltaics, heat pumps, storage, charging infrastructure, and tenant-facing electricity visualization. It also discloses operating metrics such as serving more than 20,000 households since 2017, working with 250 housing-sector customers, and generating 30,000 MWh of electricity annually. The limitation is that, from an enterprise software evaluation perspective, key information is missing around security and compliance, deployment model, permission-based collaboration, integrations, and developer support, making it difficult to compare directly with standard SaaS platforms.

Best Fit and Access from China

einhundert is better suited to German or European housing companies, housing cooperatives, and real estate asset managers looking to decarbonize residential buildings and transition tenants to photovoltaic power and low-carbon heating. Access from China is not discussed in the source text and is therefore marked as unknown. Because energy services depend heavily on local electricity policy, grid connection, metering, and contract systems, Chinese companies with similar needs would usually be better served by local integrated energy service providers, campus/building energy management platforms, or distributed photovoltaic operation solutions.
