Venture Capital Investors in Built Environment

Climentum Capital is a European venture capital firm investing in early-stage climate hard tech companies driving the sustainable reindustrialization of Europe. The firm backs B2B technologies addressing emissions and resource constraints across energy, industry, infrastructure, and supply chains. Climentum focuses on companies moving from early commercialization toward industrial scale, providing capital and operational support for hardware, deep tech, and first-of-a-kind deployments. Its portfolio spans seven European countries and includes companies working across industrial decarbonization, energy systems, resilient supply chains, and climate infrastructure.

Extantia is a Berlin-based climate tech venture firm that backs pioneers reimagining industries. The firm invests in software and hardware with large, near-term market opportunities: companies that can make a cleaner path also the faster or cheaper path for customers. Founded in 2020, Extantia describes itself as a climate tech generalist rather than a single-vertical specialist. Energy, industrial processes, buildings, transportation, and carbon removal all sit inside the mandate when the commercial wedge is clear. The sweet spot is early stage, roughly seed to Series A, with a primary focus on European founders and team coverage across Germany and the UK. The firm closed its Extantia Climate Flagship II vehicle at about €204 million, above a €150 million target, with institutional LPs that have included the European Investment Fund, KfW Capital, and other European public and private investors. Extantia also built Extantia Ignite, an internal sustainability and science capability used for impact analysis, and has tied part of manager economics to sustainability targets. Beyond writing checks, Extantia markets itself as a long-term operating partner on commercialization, organization building, and fundraising. For founders evaluating European climate VCs, the combination of a sizable flagship fund, generalist sector scope, and an explicit science/ESG process is the main differentiator.

Icehouse Ventures is a New Zealand venture capital firm backing Kiwi founded companies with the potential to scale into global markets. The platform traces its roots to Ice Angels, launched in 2003 as New Zealand’s first angel investment network. It raised its first fund in 2013 and formally became Icehouse Ventures in 2019, when Simplicity KiwiSaver, Jarden, and Sir Stephen Tindall’s K1W1 joined as shareholders. Today, Icehouse Ventures manages a range of investment vehicles spanning pre seed through pre IPO, supported by a co investor network of more than 3,000 investors. The firm says it has invested more than $800 million across more than 390 Kiwi founded companies. Its portfolio includes some of New Zealand’s better known technology companies, including Halter, Crimson Education, Sharesies, Partly, Hnry, Dawn Aerospace, Tracksuit, Tradify, Ethique, Basis, Fuel50, and Spalk, alongside international investments such as Wayve, Substack, and Nuro. Growth Fund III is currently being marketed as an open investment vehicle. Icehouse Ventures is a generalist technology investor rather than a dedicated climate fund, but sustainability is part of its broader investment framework. The firm publishes a Responsible Investment Policy aligned with the UN Principles for Responsible Investment, and Principal Bex Gidall leads both the Arc Fund and Sustainable Technologies Fund. Its climate and impact related portfolio includes companies such as Neocrete, which develops additives designed to reduce cement use in concrete, and Ethique, a solid personal care brand focused on reducing packaging waste.

Prelude Ventures is a climate venture firm that invests across the technologies needed to rebuild a low-carbon economy. Climate is not a side sleeve. It is the whole mandate: built environment, carbon management, compute, energy, food and agriculture, manufacturing and industrials, and mobility. The firm screens for impact and invests for scale. In practice that means looking for category-defining companies that can create lasting climate benefit and still become large businesses. Prelude has been an early and consistent co-investor alongside other specialist climate funds, and it is comfortable across software, hardware, and deep technical work when the company can grow inside real markets. Public fund data has pointed to a large Climate Fund II vehicle (reported around $850 million), which places Prelude among the more capitalized dedicated climate VCs. Typical check sizes cited in market databases often land from about $100,000 to $5 million depending on stage and role, with the ability to stay involved as companies mature. For founders, Prelude is most relevant when the product sits in a hard climate category and needs a partner that already lives in those markets: grids and buildings, industrial processes, carbon removal and measurement, climate-relevant compute, or low-carbon mobility and food systems.

Pulse Fund is a climate venture capital firm investing in early-stage companies across four interconnected sectors: food and agriculture, energy transition, infrastructure, and mobility. Founded in 2022 by Tenzin Seldon, the firm focuses on scalable solutions that address climate challenges across multiple industries. In September 2026, Pulse announced the $63 million close of its inaugural fund. Its portfolio includes Mast Reforestation, Twelve, Endera Motors, InventWood, BlocPower, Floodbase, Plantible Foods, and other climate technology companies. Beyond capital, Pulse provides strategic guidance, industry connections, operational support, governance expertise, and access to additional financing. Its investment approach emphasizes commercially viable solutions with long-term environmental impact, guided by a philosophy it calls Pulse Time: generating returns today while building for the next century.

World Fund is a European climate tech venture firm that backs founders building the technologies Europe needs to compete and to cut emissions at industrial scale. The firm is based in Berlin, with a wider footprint across Munich, Cologne, and Amsterdam, and it concentrates on deep tech in energy, industry, and food and agriculture. Unlike broad climate funds that stretch from consumer brands to carbon software, World Fund is explicit about hard technology and measurable decarbonization. Every opportunity is assessed through a Climate Performance Potential lens: can this product cut meaningful emissions if it scales, and can it win commercially in a real market? That framing is meant to keep climate impact and financial performance on the same page, not in separate decks. The founding partners include Daria Saharova, Danijel Višević, Tim Schumacher, and Craig Douglas. The first fund closed around €300 million, reported as one of the largest debut climate VC funds in Europe, with room for roughly 25 to 30 core investments and substantial follow-on capital. The team has been public about reserving a large share of the fund for later rounds, because European climate companies often struggle to bridge the Series B gap. Portfolio companies sit in the physical economy as much as in software. Examples that show the range include battery recycling (Cylib), industrial and building energy (Enerkii, aedifion, ecoworks), alternative proteins and food tech (Planet A Foods, Juicy Marbles, ENOUGH), and deep tech such as IQM Quantum Computers and Space Forge. For founders, the useful signal is simple: World Fund wants durable technology businesses with climate math that survives scrutiny.
