  • Overstory

    Led · Series B · Nov 2025

    Overstory builds an AI-driven grid-resilience platform that analyzes high-resolution satellite data to identify vegetation and infrastructure risks for electric utilities. Its software pinpoints tree-by-tree threats, helping utilities reduce outages, prevent wildfires, and optimize maintenance budgets. The company recently introduced the next generation of its Wildfire Intelligence product, featuring a proprietary Fuel Detection Model that locates the highest-risk fuels and recommends precise mitigation actions. Overstory reports that it now serves six of the ten largest utilities across the Americas. The team has grown to more than 80 employees representing 16 nationalities and spans machine learning, data science, arboriculture, and wildfire expertise. With new leadership from incoming COO Tamara Mendelsohn, the firm plans to accelerate AI risk-model development, broaden its wildfire-prevention suite, and expand its global footprint. Overstory maintains dual headquarters in Boston and Amsterdam.

  • Vyntelligence

    Led · Series B · Nov 2025

    Vyntelligence, based in London, has built Vyn® SmartVideoNotes®, an AI-powered platform that captures short contextual videos from customers, contractors, and employees and converts them into structured, actionable insights.

  • Aerones

    Participated · Equity · Jun 2025

    Aerones develops patented robotic systems and AI-driven solutions for inspection, maintenance, and predictive services for wind turbines. The company serves major operators and its customers represent over 50% of global wind power capacity, including NextEra, GE, Vestas, Enel and Siemens Gamesa. Led by CEO Dainis Kruze, Aerones combines robotics, AI and manufacturing to deliver remote and automated turbine services. The company plans to expand globally, boost R&D in AI and robotics, scale manufacturing, and enhance predictive maintenance for the wind industry. Recent public funding milestones include a €4M grant from the EU Innovation Fund in 2024 and a $30M funding round in 2023, reflecting ongoing capital support for growth. Aerones develops and deploys patented robotic systems for wind turbine operations, focusing on inspection, maintenance and leading-edge blade repairs. The company plans to produce and deploy the world’s first wind turbine blade leading-edge repair robot sets using EU grant funding. Its services include external and internal blade inspection, lighting protection checks, ultrasound, painting, ice-phobic coating, cleaning, and leading-edge repairs. Aerones says its robotic technology performs crucial tasks 3x–6x faster and yields up to 10x fewer idle stay days than conventional methods, and it operates in more than 27 countries. The firm aims to cut repair downtime dramatically (targeting repairs within 18 hours and a 67% reduction in downtime) and to support the transition to renewable energy. Financially, Aerones secured a €4,416,000 grant from the EU Innovation Fund for a project with a total budget of €7,360,000, and it raised €27M in growth capital just over a year earlier in a round co‑led by Lightrock and Haniel. Founders Dainis Kruze and Janis Putrams lead the company from Riga, Latvia. Aerones offers a patented modular robotic solution that delivers a full suite of wind-turbine services including external visual and internal blade inspections, lighting-protection and ultrasound checks, painting, ice-phobic coating, cleaning, and leading-edge repairs. The company began offering basic inspection services in 2019 and has since expanded its capabilities to comprehensive maintenance and repair work. Aerones serves customers that represent roughly 50% of the world’s wind power capacity, including NextEra, GE, Vestas, Enel and Siemens Gamesa. The company is led by CEO Dainis Kruze and maintains a European headquarters in Riga, Latvia, and a North American headquarters in San Jose, USA. Aerones raised $30M in funding and plans to use the capital to grow technical and sales functions, increase the number of robot service teams, and expand into new markets. No revenue or other financial metrics were disclosed in the article. Aerones is a startup focused on developing robotic systems for cleaning wind-turbine blades. The company announced a $9 million fundraising to support development of those cleaning robots. The article frames the financing as targeted toward product development rather than reporting operating metrics. Public commentary quoted in the article praised the team and the concept of applying robotics to such maintenance tasks. Other commenters raised broader points about rising costs in green energy and suggested alternatives like self-cleaning or low-soiling blades. Aerones has shifted from using large industrial drones to a ground-based robotic system for wind turbine inspection and maintenance. The system combines a computerized winch, a robotic arm, and a small fleet of ground robots to perform tasks such as close-up photography, laser scanning, lightning conductivity tests, blade and drainage-hole cleaning, and coating application. Its design enables a two-man crew to service multiple turbines per day, including some nighttime and low-temperature operations. Aerones says the ground system is more stable and effective than its prior drone approach and has already been piloted in the U.S. and Europe. The company is Y Combinator–backed and moved from Latvia to the San Francisco Bay Area. The new funds will be used to further develop the robotic system and expand further into the U.S. market.

  • Neustark ag

    Participated · Equity · Jun 2024

    Neustark has developed an IP‑protected solution that captures biogenic CO2 from biogas plants, liquefies and transports it to construction‑waste recycling sites, and injects it into concrete granulates and other mineral waste to trigger accelerated mineralization and permanent storage. The carbonated recycled aggregate can be used to build roads or produce fresh recycled building materials; Neustark says the mineralization stores CO2 for hundreds of thousands of years. The company has deployed its solution at 19 sites and has 40 additional plants under construction across Europe. Neustark has sold nearly 120,000 tons of carbon removal to date and certifies projects under the Gold Standard. The company is scaling globally with plans to expand across Europe, enter North America and Asia‑Pacific, and aims to permanently remove 1 million tons of CO2 by 2030. Founded in 2019 and based in Berne, Switzerland, Neustark is a team of around 60 people (Q2 2024). Neustark is a Bern‑based company that captures CO2 at biogas plants, liquefies it and enables permanent storage — including enrichment of demolition‑concrete granulate and geological storage abroad. The firm manages the full value chain from capture and liquefaction to transport (rail, ship, truck), storage in target countries (e.g., Iceland, Norway) and third‑party certification of climate benefit. Its core product is a CO2 removal service for point sources, with processes to incorporate CO2 into building materials or store it underground. The company was awarded two projects by the Stiftung Klimarappen and will use the funding to scale its core activities and to explore expanded geological storage pathways. Co‑CEOs and founders Valentin Gutknecht and Johannes Tiefenthaler are quoted on accelerating scaling and unlocking geological storage potential. Operational metrics disclosed in the press release include contracted removal volumes of 16,500 t CO2 (concrete storage) and 13,000 t CO2 (geological storage), totaling 29,500 t of sold CO2.
