- ScyAI
Led · Seed · Feb 2026
ScyAI is a Zurich-based startup that has built a risk-intelligence platform for organisations managing extensive real-asset portfolios such as manufacturing plants and energy facilities. The software ingests customers’ operational data and combines it with external hazard models to generate detailed, auditable risk profiles that mirror the metrics used by insurance underwriters. By making site-specific risk transparent, the tool enables companies to identify coverage gaps, negotiate improved policy terms and, according to early users, lower their premiums. The company positions its product as a solution to the growing protection gap created by climate-driven natural catastrophes and coarse insurance pricing models. CEO and founder Bernhard Rannegger emphasises that rising physical climate risks are becoming a core operational and financial concern for asset-heavy industries. ScyAI plans to use its newly raised capital to refine the platform and expand its reach to additional sectors with significant infrastructure exposure. The €2 million pre-seed round provides the company with its first external institutional capital, anchoring its initial go-to-market efforts.

Founded in August 2025 by Dila Ekrem, Duc-Trung Nguyen, and Leon Stawowiak, the company aims to evolve into a full end-to-end platform for construction stakeholders. With its newly raised capital, Arctis AI plans to expand its technical team, roll out new product modules, and scale customer acquisition across Europe.

No revenue, user, or ARR figures were disclosed in the article, underscoring the company’s early development phase.
- TUAL
Led · Equity · Jan 2026
TUAL designs and manufactures the PowerUp battery-buffered DC charging system aimed at providing dependable, high-power charging for commercial EV fleets, ports and industrial operators. Its infrastructure-led model integrates on-site battery storage to mitigate grid constraints and reduce downtime risk for ‘mission-critical’ vehicles. With new capital in hand, the company plans to accelerate engineering work and move the PowerUp unit into full-scale production. Management also intends to expand and validate field operations across the UK before launching more broadly in Europe. Investors praise TUAL’s ability to deliver scalable, battery-integrated infrastructure that supports large-scale electrification. While no revenue or user figures were disclosed, the company emphasises the complex financing and deep energy expertise required for next-generation charging infrastructure.
- Voltfang
Participated · Series B · Jun 2025
Voltfang develops high-performance European battery storage systems built from requalified EV batteries for industrial, commercial and grid-scale customers. Its core product pairs energy-dense battery modules with an intelligent energy management system, Venma, which uses AI to maximise self-consumption, lower electricity costs and enable participation in energy markets. Customers include Aldi Nord, Alba Group, Fiege Logistik and Goldbeck. The company opened the "Voltfang Future Fab" in Aachen to scale production and enable capacity up to 1 GWh, and aims to deliver an additional 250 MWh of storage across Europe by the end of 2026. Storage capacity grew from 5 MWh in 2023 to 20 MWh in 2024, and Voltfang targets supporting the replacement of the Weisweiler coal-fired power plant by 2030. By using second-life and surplus batteries sourced from the European automotive industry, the company seeks to reduce reliance on Asian supply chains and foster a resilient European battery industry. Voltfang develops green energy storage systems built using requalified electric vehicle batteries, pairing hardware with an advanced Energy Management System. The company aims to broaden its product offerings and invest further in its EMS to maximize battery performance. Voltfang targets commercial/industrial and grid-scale applications and emphasizes circular-economy principles and reuse/second-life concepts. Management plans to deploy an additional 40 MWh of battery capacity by 2025. The company recently completed an oversubscribed financing round, which it closed within three months, strengthening its growth outlook and market position in sustainable energy infrastructure. Voltfang, based in Aachen, builds stationary energy storage systems from used electric vehicle batteries and uses AI-based software to evaluate battery longevity. Its operating system and continuous monitoring aim to make second-life batteries as durable as new ones, backed by a 10-year "Batteryflat" guarantee. The company has completed successful pilot projects in Germany and lists Aldi NORD and Schaltbau among its clients. Voltfang says the systems can be intelligently deployed to amortise batteries quickly and support grid stability amid rising electrification. Management highlights the ability to connect urgently needed capacity to the grid to help avoid blackouts. The company has raised €5 million to scale its production.
