  • Aisel Health

    Participated · Seed · Aug 2026

    Aisel Health has built a clinical operating system tailored to psychiatric workflows that converts interview recordings, documents and patient accounts into structured insights clinicians can access during consultations. The company positions its product around information retrieval rather than solely speeding note-taking, distinguishing it from generic AI scribe tools. Founded in 2024 by Augusta Klingsten Peytz and Christian Houen, Aisel is collaborating with private clinics in Denmark and has research partnerships with Region H, the University of Southern Denmark, and MedTech Growth at the Technical University of Denmark. Financially, it recently closed a €1.7M pre-seed round led by Caesar Ventures, with follow-on capital from Nordic Web Ventures, LifeX, Angel Invest and returning investors Rockstart and EIFO. Aisel plans to use the proceeds to hire clinical and engineering talent and to enter the UK market prior to raising a seed round.

  • RTDT Laboratories

    Participated · Seed · Jul 2026

    RTDT Laboratories designs ultra-thin, lightweight wireless sensor patches that integrate microelectronic sensors and proprietary algorithms to capture real-time aerodynamic and structural data from wind turbine blades. The patches measure parameters such as aerodynamic pressure, acceleration, vibration, mechanical load and temperature, synchronize timestamps, and transmit data wirelessly to a gateway and then to the cloud to build a digital twin of the blade. Their software suite performs calibration, local and global analyses (including blade kinematics and pressure coefficients), visual analyses and decision recommendations for control, design optimization and maintenance. The patches attach with removable tape without drilling, are offered in two sizes (400×160×4 mm and 160×160×4 mm), and include photovoltaic cells and intelligent battery management for ultra-low-power operation. RTDT was founded in 2022 as an ETH Zurich spin-off by Imad Abdallah, Aris Mukherjee and Konstantinos Tatsis and is pursuing pilot implementations and commercial deployments in the wind-energy sector with a target for large-scale rollout by early 2027.

  • Foovi

    Participated · Equity · Apr 2026

    Foovi develops a web-based platform for food and drink producers to manage products, customers, orders and invoicing in one place.

  • Another Earth

    Participated · Equity · Mar 2026

    Another Earth develops a generative-AI and 3D-modeling platform that produces synthetic, fully labelled satellite imagery and geospatial datasets. By removing the need for costly real-world imagery and manual annotation, the system lets organisations train and test Earth observation algorithms more quickly and at lower cost. The technology is already being used with GeoTerra Image in Sub-Saharan Africa to track the environmental impact of mining and industrial operations, and the company has partnered with NovaTerra in Brazil to support deforestation monitoring, agricultural analysis, and climate-risk assessment. With its Synthetic Data Engine, Another Earth aims to move customers from reactive crisis response to proactive, predictive intervention across land, water, and infrastructure applications. The Vienna-based startup intends to deploy its platform across Latin America and Africa, concentrating on biodiversity monitoring, deforestation tracking, and broader environmental risk analysis. To date, it has secured €3.5 million in external funding to accelerate product deployment and international expansion.

  • SenseUP

    Participated · Seed · Jan 2026

    SenseUP is a Cologne-based ag-biotech startup creating double-stranded RNA (dsRNA) biopesticides that selectively disable pests via RNA interference while sparing soil, plants, and wildlife. Its key innovation is engineering Corynebacterium strains that both encapsulate dsRNA inside robust cell walls and produce it at high titers, giving the products 18-plus months of room-temperature stability and production costs that can compete with synthetic chemicals. Proprietary fluorescence-activated biosensors screen millions of strains per second, allowing rapid identification of top dsRNA producers and enabling single products that can target multiple pests simultaneously. The company has completed initial field trials and is now advancing roughly 15 product candidates, with greenhouse and expanded field results expected in 2026. SenseUP plans to submit regulatory dossiers and commercialize through partnerships with major agricultural firms, initially focusing on the U.S. and South American markets while also eyeing Europe. The seed financing provides capital to expand its portfolio, grow its team, and deepen strategic collaborations. No revenue figures have been disclosed, and this seed raise represents the first publicly reported external funding for the company.
