  • Nanordica Medical

    Led · Equity · Jun 2026

    Nanordica Medical’s core product, Premotiv, is a patent-protected wound dressing designed to prevent infection while promoting healing without relying on systemic antibiotics. In a randomised controlled trial of 30 patients with diabetic foot ulcers, Premotiv demonstrated a 43% reduction in wound area after one week versus 13% with standard silver dressings, with results published in the Journal of Wound Care. The company is conducting a larger multicentre, double-blind, randomised clinical trial with more than 120 patients enrolled to generate stronger evidence for reimbursement and guideline adoption. Nanordica launched a veterinary product, Ravimus Vet, in 2023 which is distributed in six countries, and has been awarded a European patent. The company has received a €2.4 million EIC Accelerator grant to support clinical and development activities and intends to pursue CE marking for the human product prior to European launch.

  • CeLLife Technologies

    Participated · Seed · May 2026

    CeLLife Technologies develops a battery quality and health intelligence platform underpinned by its patented Electrical Fingerprint (EFP™) technology, which captures rich battery measurement data in seconds and converts it into diagnostics, traceability, and decision support. The technology is chemistry-agnostic and works across NMC, LFP, NCA, solid-state, and sodium-ion cells, and is protected by multiple granted patents. The company has already secured paying customers across three market segments and signed a major commercial contract with a leading European recycling company. CeLLife was named among the Top 10 winners of the European Startup Prize for Mobility in 2025. Following the close of a €4 million post-seed round, the company plans to accelerate commercial rollout and scale operations across Europe and North America, focusing on recycling, module and pack assembly quality control, and BESS condition monitoring. Its platform strategy is positioned to address growing demand for battery traceability and lifecycle intelligence under the EU Battery Regulation, including upcoming battery passport requirements.

  • TheStorage

    Participated · Seed · Apr 2026

    TheStorage develops a sand-based thermal energy storage system that stores and releases heat to help industrial operators electrify heat processes and integrate renewable electricity. Its technology aims to reduce energy costs and emissions compared with fossil-based heat systems while enabling participation in electricity market and grid balancing opportunities. The company emphasizes high-efficiency heat transfer and integration with existing industrial processes. TheStorage recently raised €3.6 million in a seed round to accelerate commercialisation, expand its team, and continue technology development. Leadership includes CEO and co-founder Timo Siukkola, who has cited strong industrial interest in thermal energy storage. The company plans to scale its solution globally as industries seek to decarbonise heat and improve energy flexibility.

  • Groundhawk

    Led · Seed · Mar 2026

    Groundhawk is a Finnish infrastructure software company that replaces analogue, post-construction surveys with real-time, centimetre-accurate 3D mapping of underground utilities. Using high-precision satellite positioning, 3D scanning and AI analytics, its handheld device lets on-site crews capture depth measurements, installation details and visual evidence while trenches are still open; the data is instantly synced to a cloud dashboard. This workflow turns documentation into an active quality-control tool, enabling project managers to spot and fix issues immediately and delivering up to 50 % cost savings on traditional surveying. The platform already serves major Nordic and European contractors such as Eltel Networks, Voimatel, Elvera and Signal Group, which in turn work with network operators like Telia, Telenor and E.on. Groundhawk aims to become the standard infrastructure data-capture platform across Europe and plans to extend beyond the continent in 2027. With fresh seed capital, the company will scale its B2B sales force across Germany, the UK, Benelux and the Nordics, expand its engineering team, and add planning and predictive QA features. To date it has raised €2 million and is in an early-revenue phase backed by strong customer traction.

  • Renewcast

    Led · Safe · Sep 2025

    Renewcast provides AI-powered forecasting solutions for the renewable energy sector using proprietary digital twin technology to model weather patterns and asset conditions for intra-day, day-ahead, and multi-day forecasts. The platform serves utilities, grid operators, and renewable asset managers, and has over 1.8 GW of installed renewable capacity under active clients. The company runs more than 10 pilot programs and serves four commercial clients in Europe and the US, and it reports having scaled more than 2.5x year-on-year. Renewcast consistently outperforms legacy systems with 20–40% improved accuracy and is credited with generating millions in annual value through reduced balancing costs. The business plans to accelerate global commercial rollout across Europe, the US, Latin America, India, and Asia, consolidate its tech team, and ramp up commercial efforts. Renewcast was founded in 2020 and is preparing for a Series A in late 2026. Renewcast develops advanced wind power generation forecasting delivered through a fully automated Azure Cloud–based platform. The company says its forecasts offer materially higher accuracy — a cited customer reported 20–30% better reliability versus their benchmark. Renewcast targets utilities and corporate clients and aims to serve a global portfolio of customers. The team is led by CEO and founder Fabio Nicoló and counts strategic partners such as MindTitan. The company plans to use new funding to accelerate market penetration and enhance its technological capabilities. Quotes from investors highlight the large market opportunity driven by fluctuating energy prices and the need for reliable renewable production forecasting.
