Polarstern GmbH

cleverwatt is the autopilot for industrial energy systems. Our energy management platform controls and automates PV systems, battery storage, charging infrastructure, cooling, compressed air, and other flexible loads intelligently and in real-time. Our approach combines economic optimization with technical implementation during ongoing operations and delivers real, measurable results: more than 30% lower energy costs, significantly reduced peak loads, and a return on investment for battery storage of under three years. While many solutions merely visualize data or calculate theoretical potentials, cleverwatt implements optimization fully automatically. clever.Report identifies savings potential transparently and based on facts, cleverEMS controls energy systems adaptively and dynamically in practice, without additional effort for our customers’ teams. This optimizes grid fees, maximizes the efficiency of PV and battery storage, leverages flexibility profitably, and actively realizes marketing options such as on-site or off-site PPAs and direct marketing. Our mission is to turn energy planning into real energy optimization. Our technology makes companies more resilient to price volatility and regulatory changes while creating sustainable economic benefits. We believe in transparency, collaborative partnerships, and that energy management should be measured above all by results, not by presentations or white papers. cleverwatt is designed for industrial and commercial operations that aim not just to monitor energy costs, but to actively and intelligently manage them. For anyone who doesn’t want to wait for the market to change, but wants to shape the future of energy supply themselves.

Linkvolt automates charging electricity billing for property operators and companies on existing charging hardware. As a technical intermediary, the platform handles metering, allocation, and legally compliant billing for every charging session. Linkvolt provides the billing layer but does not buy or sell electricity itself. Operators such as property managers, real estate companies, and business parks use Linkvolt to bill third parties for charging electricity—guests, tenants, and regular users. Every charging session is automatically recorded, documented in a legally compliant manner, and settled without manual effort. Companies distribute charging electricity internally to employees and their own vehicle fleets. Linkvolt assigns each transaction to the correct person and cost center and provides the export ready for accounting, including for DATEV. This makes billing for company cars and shared vehicles a one-click process. What distinguishes Linkvolt from pure charging billing is the next expansion step: integrating locally generated solar power directly into the same billing system, delivering higher margins for operators and cheaper charging for users, instead of feeding solar power into the grid at low compensation rates. The business model is purely transactional, with a few cents per kilowatt-hour mediated. Pilot operations begin in summer 2026 in Munich with 10 to 20 households in one building; the scaling potential extends across over 3 million PV systems in Germany and a rapidly growing number of electric vehicles in residential and commercial buildings.

The 2n8life GmbH develops a user-friendly system for measuring nocturnal erections including an app for visualizing the results. A textile cuff is worn overnight by the man. It measures erections and sends them via Bluetooth to the smartphone. In the app, the user sees his results in the context of the comparison group. The main applications are differential diagnostics for erectile dysfunction (organic or psychological causes) and use as a digital biomarker for cardiovascular diseases.
