  • LawX

    Participated · Seed · May 2026

    LawX develops an AI-driven platform that automates operational processes for law firms and notaries, including data capture, workflow management, document handling, contact and calendar management, and billing. The platform combines case management, workflow automation, document processing, communication management and billing within a single system. LawX positions itself to address fragmented legacy systems and labour shortages that leave many operational tasks manual across the legal sector. The company plans to expand its product offering into the broader law firm market and aims to become a leading operating system for legal work across Europe. Following its €7.5 million seed raise, LawX intends to use the funding to continue product development, expand the platform, and scale sales and customer support functions.

  • Zentio

    Participated · Seed · Dec 2025

    Berlin-based Zentio has developed a production-planning platform that leverages AI agents, mathematical optimisation, and real-time shop-floor data to help industrial companies make faster, better-informed decisions. By structuring and centralising operational and machine information, the system lets manufacturers anticipate capacity needs, respond to breakdowns or material shortages, and adjust shift schedules on the fly, boosting productivity and minimising downtime. Founded in 2025, the company is working with a network of pilot customers and strategic partners across Europe. Zentio’s self-learning flywheel approach turns operational data into a strategic asset, aiming to elevate decision-making standards across European manufacturing. The fresh capital will be used to advance its core mathematical systems, machine-learning pipelines, and agentic UX, while growing the engineering team to build the first generation of AI-native production-planning tools. No operating metrics such as revenue or user counts were disclosed.

  • Onsai

    Led · Equity · Aug 2025

    Founded in 2024 in Leipzig by former hoteliers Ralf Bonin, Christian Müller, and Tobias Koehler together with AI specialist Jochen Emig, Onsai builds round-the-clock AI "employees" that answer calls, manage reservations, and resolve everyday guest inquiries. The software is already in use at hotel groups such as McDreams Hotels and Homaris, where early results indicate operating cost reductions of up to one-third and measurable relief for human staff. Onsai targets the acute talent shortage afflicting 84 % of German hotels and plans to connect its technology to additional property-management systems while releasing new AI agents over the next year. With adoption of AI in European hotels still at only 41 %, the company sees significant upside and intends to use fresh capital to accelerate European expansion and grow its team. Onsai’s product portfolio is being positioned as a strategic must-have rather than a convenience tool for hoteliers. No revenue or user figures were disclosed, but management emphasizes efficiency gains and cost savings as key operating metrics.

  • Leapter

    Participated · Seed · Jul 2025

    Leapter is an AI-native platform that turns business needs into clear, visual, executable blueprints that serve as a single source of truth for projects. By changing the medium from code to structured visual diagrams, Leapter enables cross-functional collaboration among product leaders, analysts, compliance, legal teams, and engineers, making systems auditable and verifiable. The platform is designed to bridge the gap between AI speed and human oversight, reducing the risk of untrusted AI-generated code and promoting correct-by-design implementations. Leapter is Germany-based and currently operating in private beta with a group of early design partners. The company secured €2 million in pre-seed funding to support growth. With the new funding the team plans to grow engineering capacity, further develop its visual language, and roll out additional enterprise integrations.
