  • FINN

    Participated · Series D · Jun 2026

    FINN operates a multi-brand car subscription service that lets customers subscribe to vehicles fully online with insurance, registration, taxes, and servicing bundled into a single monthly fee and flexible cancellation. The platform features more than 25 brands including BMW, Mercedes-Benz, Hyundai, BYD, and MG. FINN has grown rapidly since its 2019 founding in Munich, reaching over 50,000 active subscriptions and annual recurring revenue of more than €300 million. Reported revenue rose from €3.2 million in 2022 to €444 million in 2024, representing a two-year compound annual growth rate of 1,078%. The company employs roughly 484 people as of 2025 and plans to expand its subscription fleet, improve profitability, and continue enhancing its technology. FINN faces competition from players like Sixt+, Onto, and Free2Move and acknowledges macroeconomic sensitivity given subscription pricing versus traditional leasing.

  • Photonic

    Led · Series E · May 2026

    Photonic pursues a distributed approach to quantum computing through its Entanglement First architecture, which combines silicon-based qubits with native photonic connectivity to enable scaling across existing telecom fiber infrastructure. The company positions this architecture as a path toward fault-tolerant, commercial-scale quantum systems that can interoperate with global cloud and telecom networks. Photonic is engaged in programs including Canada’s Quantum Champions Program and Stage B of DARPA’s Quantum Benchmarking Initiative. With the recent financing, Photonic has raised over $350 million USD to date and closed a round valuing the company at $2.0 billion USD post-money. The firm says it will use the new capital to advance platform development, deepen telecom and strategic partnerships, grow its team, and pursue near-term milestones. Investors supporting Photonic range from government development banks and national telecoms to multinational strategic and growth equity backers.

  • Oviva

    Participated · Series D · Jan 2026

    Founded in 2014 by Kai Eberhardt and Manuel Baumann, Oviva pairs a medical-device-certified mobile app with remote multidisciplinary care teams to provide evidence-based lifestyle and behavioural interventions for weight management and chronic illnesses. The platform’s embedded AI personalises treatment pathways, supports clinicians’ workflow, and maintains consistent quality at scale. Integrated into national reimbursement schemes such as Germany’s DiGA, the UK’s NHS, and Switzerland’s health system, Oviva removes long wait times and geographic barriers for patients. More than 1 million patients have already used the service, and 90+ clinical studies support its long-term efficacy. Unlike competitors such as Kry/Livi, HelloBetter, Omada Health, or Noom, Oviva focuses on reimbursed, weight-related and metabolic care in European public systems. With fresh capital, the company plans to extend its digital programmes to additional chronic indications, including hypertension and type 2 diabetes, to better manage comorbidities. The €200 million Series D provides significant resources for product expansion and deeper market penetration across Europe.

  • Commonwealth Fusion

    Participated · Series B · Aug 2025

    Commonwealth Fusion Systems is developing SPARC, a fusion demonstration machine designed to generate net energy, and ARC, a planned grid-scale fusion power plant to be built at the Fall Line Fusion Power Station in Chesterfield County, Virginia. The company has raised $4 billion since its founding in 2018 and says the financing will accelerate commercialization and complete SPARC assembly. CFS has strategic partnerships with Dominion Energy and counts Google and Eni among its investors, with the latter two also signing power purchase agreements to buy more than half of ARC’s projected output. The company has submitted an application to PJM Interconnection and is targeting early-2030s grid delivery. CFS emphasizes its execution track record, peer-reviewed science, and the assembly progress of SPARC as evidence attracting institutional capital.

  • Submer

    Participated · Equity · Oct 2024

    Submer develops immersion cooling systems that operate entire server racks inside vessels filled with a proprietary, biodegradable, non-conducting coolant (which the company says has the viscosity of water). Its product lineup includes a range of immersion fluids and smart containers designed for servers, and the company reports agreements with major server OEMs including Dell and Intel. Co-founded by Pol Valls (currently CFO) and CTO Daniel Pope, Submer counts at least one hyperscaler, telecoms like Telefónica, corporates such as ExxonMobil, the European Commission, and major research centers among its customers. The founders developed the solution drawing on retired industrial engineers and material scientists, and the company has been building an ecosystem of compatible server components. Submer has raised $55.5M in the current round at an implied valuation of about $500M and—per PitchBook—has now raised around $100M total. The startup recently appointed Patrick Smets as CEO in January 2024 and plans to use the new funding to scale its business and expand partnerships and customer deployments. Submer develops an immersion-cooling system that operates servers submerged in an eco-friendly, non-toxic, non-flammable and biodegradable fluid housed in specialized containers. The company says the approach can reduce energy consumption by 50%, cut water use by 99%, and take up 85% less space. Founders Pol Valls and Daniel Pope developed the technology with retired industrial thermodynamics engineers and reached a viable product after six prototype iterations. The founders briefly advanced to final interviews with Y Combinator but were not accepted. Submer positions its technology for edge and urban deployments where low-latency applications (5G, smart cars, IoT) require compute closer to users and contrasts its approach with large-scale experiments like Microsoft’s underwater servers. The market opportunity is cited at about $25 billion (Global Market Insights) and the company recently raised roughly $12 million in new financing led by impact investor Norrsken VC and Tim Reynolds.
