Blue Action Accelerator is an ocean and climate accelerator for pre-seed and seed startups in the blue economy. Each company receives $150,000 and a four-month program covering product, operations, commercialization, data science, partnerships, and fundraising. Founders get access to testing grounds in Freeport, Grand Bahama, including coral reefs, seagrass meadows, mangroves, and shared research facilities in the free-trade zone. The program also connects companies with public and commercial partners, including the Grand Bahama Port Authority, the governments of Barbados and Jamaica, and ports in San Diego, Los Angeles, and Miami-Dade County. Focus areas include coastal carbon capture, marine ecosystem restoration, island infrastructure, ocean energy, aquaculture, clean maritime transport, and software that supports those industries. Blue Action Accelerator is a collaboration between Blue Action, a Bahamas-based ocean innovation hub, and Founders Factory, with additional ties to Austin, New York, and London.

Climate Asset Management is an investment manager focused on climate solutions across natural capital and climate infrastructure strategies. The firm works at the intersection of institutional capital and measurable climate outcomes, targeting assets and projects that can scale mitigation and resilience.

Counteract is a London-based venture firm focused almost entirely on carbon removal. While many climate funds mix efficiency, electrification, consumer brands, and occasional removal bets, Counteract specializes in technologies and tools that take greenhouse gases out of the atmosphere or lock them away for the long term. The first fund, Counteract One, is an early-stage vehicle (often described around £35 million / about $42 million) structured as an EU Article 9 strategy. It invests globally at pre-seed and seed, with a stated ambition to help catalyze on the order of 5 gigatonnes of CO2e removal potential by 2050. That framing matters: the firm is underwriting additionality and scale pathways, not only short-term offset demand. Portfolio work spans a wide removal stack. Direct air capture and mineralization sit alongside biomass pathways, ocean and coastal approaches, enhanced weathering, carbon-negative materials and fertilizers, and the measurement and verification software that keeps removal markets honest. The common thread is whether a solution expands durable removal capacity. For founders, Counteract is one of the clearest specialist VCs to approach when the product is removal-native. For LPs and ecosystem partners, it fills a gap between generalist climate VC and project finance that arrives too late for first-of-a-kind technology.

EIT Climate-KIC is Europe's leading, independent climate innovation agency and community, working to create climate-resilient societies and fight the climate breakdown. Initiated by the European Institute of Innovation and Technology (EIT), Climate-KIC bridges the gap between climate commitments and current reality through innovation and systemic change. The organization works hand-in-hand with countries, regions, cities, and businesses across the globe to mobilize systems change and accelerate climate action. Climate-KIC orchestrates place-based transformations that ground climate action at the local level, prioritizing solutions developed and implemented in local contexts to build momentum and inspire action. Through partnerships, they generate, implement, and integrate climate solutions while facilitating learning to fuel faster and more ambitious climate action. Their work spans climate entrepreneurship, learning initiatives, and European missions including support for climate-neutral cities by 2030.

Entrepreneurs First (EF) is a global talent investor and accelerator that builds companies from exceptional individuals, often before they have a cofounder or idea. Founded in 2011 in London by Matt Clifford and Alice Bentinck, EF pioneered talent investing: matching high-potential founders, supporting them from ideation to first revenue, and backing them into Silicon Valley's top venture ecosystem across offices including London, San Francisco, and Bangalore.

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.

EY Foundation is a charitable organization that focuses on supporting young people through various programs and initiatives. The foundation works collaboratively with employer partners, schools and colleges, volunteers, alumni, and fundraising champions to deliver its mission.

The organization appears to have a structured approach with dedicated programs, policy and research initiatives, and strong governance through their board and patrons.

GSG operates through a network of national partners, taskforces, strategic partners and affiliations to drive collective action and advance impact investing globally. GSG Impact plays a crucial convening role in the impact ecosystem, bringing together diverse stakeholders to accelerate the transition toward impact-driven decision making. They matter because they serve as a catalyst for systemic change, working to ensure that all investment, business, consumption and government decisions consider their broader social and environmental implications.

Just Climate is a mission-driven investment business established by Generation Investment Management that focuses on backing high-impact climate solutions capable of radically reducing or removing emissions. The firm targets attractive risk-adjusted financial returns while prioritizing transformational climate impact, operating through a 'climate-led' investing approach that starts with identifying solutions that can make the biggest difference to achieving net zero by 2050. The firm directs and scales institutional capital toward solutions for historically hard-to-abate industries, emphasizing low or no-carbon solutions that are transformational rather than incremental. Just Climate's mission is to make climate-led investing a capital allocation imperative, focusing on solutions that can benefit people everywhere while addressing the urgent need to radically reduce all emissions by 2030.

LeapFrog Investments is a private equity firm that focuses on scaling purpose-driven businesses across Asia and Africa to achieve sustainable growth, profitability, and measurable social impact. The firm invests in companies operating primarily in three key sectors: financial services, healthcare, and climate solutions, targeting businesses that serve emerging consumers and low-income populations. LeapFrog operates on a "profit with purpose" model, partnering with business leaders to drive integrated returns that combine financial performance with social impact. Their approach is grounded in a clear theory of change aimed at empowering low-income consumers to become agents of their own transformation, providing them with tools and services to make entrepreneurial leaps out of poverty. The firm provides not just capital but also resources and expertise to help portfolio companies reach emerging consumers at scale with relevant, affordable, and essential services. LeapFrog has established itself as a significant player in the impact investing ecosystem, demonstrating that commercial returns and social impact can be successfully integrated. Their rigorous approach to impact measurement, aligned with UN Sustainable Development Goals, sets industry standards for transparency and accountability in impact investing. The firm's scale of operation, reaching 559 million people through their portfolio companies and supporting 33 million jobs, positions them as a major force in driving inclusive economic growth in emerging markets.

Lightrock is a global impact investment platform that backs technology-enabled growth companies across People, Planet, and Productivity themes. Established as an independent platform in 2021 and backed by LGT and the Princely House of Liechtenstein, it sits between growth equity and impact PE for founders scaling proven solutions. Private-market strategies include Growth Solutions, a Climate Impact Fund that closed at €860M, Latin America growth funds, and energy-access strategies such as Accelerate7 for Sub-Saharan Africa, South Asia, and Southeast Asia. Public materials cite on the order of $5.8B assets under advice at the platform level, 90+ private equity portfolio companies, and teams across four continents. Climate Impact tickets have been described in the roughly €10M to €40M range for Europe and North America net-zero companies. Lightrock typically prefers meaningful minority stakes and board participation, pairing commercial growth support with impact and ESG monitoring. The platform also has public-markets capabilities, but the directory-relevant story for most founders is private growth capital with an explicit impact frame. If you are past early product risk and need a global growth partner that still takes People, Planet, and Productivity seriously, Lightrock is a major node.

Pale Blue Dot is a Malmö-based climate venture firm started by former founders who wanted a climate-only fund with operator empathy. The firm invests at pre-seed and seed in software and hardware companies building climate businesses across Europe and the United States. The investment map is intentionally simple. Optimize: technologies that decarbonize systems that already exist. Adapt: tools that help communities and industries live with climate impacts. Pioneer: breakthroughs that redefine what a sustainable future can look like. That structure helps founders place themselves quickly without forcing every company into a single vertical label. Typical checks are about €0.5 million to €2 million, and the firm often prefers to lead. Fund I closed around €87 million. Fund II closed around €93 million, putting combined fund capital near €180 million, with plans to back several dozen companies across the two vehicles. Coverage spans food and agriculture, industry, mobility, energy, fintech-for-climate, and related enabling software. Pale Blue Dot's public posture is practical rather than theatrical. Partners emphasize trust, hands-on support, and climate impact assessed before investment. For early-stage founders in Europe or the US who want a specialist climate lead without a mega-fund process, it remains one of the clearer Northern European options.

Regeneration.VC is a venture capital firm that invests in early-stage Consumer ClimateTech startups focused on driving the circular economy through sustainable innovation in materials, consumer products, and carbon solutions. The firm specifically targets climate-focused companies that are working to transform unsustainable consumption models and create regenerative value chains. Their mission is to regenerate consumer industry value chains to meet planetary boundaries, recognizing that humanity currently consumes nearly twice what Earth can replenish and that 7 of the 9 planetary boundaries have been transgressed. They operate with a theory of change centered on transforming the "take-make-waste" consumption model that drives climate change and biodiversity loss by investing in solutions that enable circular and regenerative approaches. Regeneration.VC matters in the impact ecosystem because they take a rigorous, data-driven approach to measuring circularity and regenerative impact through their CRISP protocol, developed in partnership with Circle Economy Foundation. The fund brings together a multi-disciplined team of investors, entrepreneurs, scientists, and corporate leaders, with strategic advisor Leonardo DiCaprio, positioning them as a significant player in scaling breakthrough technologies that can deliver outsized net environmental benefits.

Steward is a mission-driven lending platform that provides flexible financing to regenerative farms and agriculture businesses focused on transforming local food systems. They partner with human-scale producers including farms, ranches, fisheries, and food producers who are implementing sustainable and regenerative agricultural practices. Their mission is to promote environmental and economic stewardship through regenerative agriculture by bridging the funding gap that many sustainable producers face when trying to access capital. Steward operates a community-lending platform that connects mission-driven lenders with agricultural projects, allowing individuals to participate in secured, interest-bearing loans that support regenerative businesses. Steward plays a crucial role in the regenerative agriculture ecosystem by championing the "unsung stewards" who are proving there's a more sustainable way to produce food while taking responsibility for soil health and local communities. They matter because they're addressing a critical need in the agricultural sector where human-scale producers struggle to access traditional financing, thus enabling the growth and scaling of regenerative practices that benefit both environmental and economic outcomes.

Systemiq Capital backs early-stage founders who are rewriting the physical economy: how we grow and process food, invent materials, move people and goods, price climate risk, and restore damaged natural systems. The fund is Europe-based and works closely with the wider Systemiq systems-change practice, which gives it an unusual vantage point on markets, policy, and corporate demand. The partnership model is built around early market adoption. Capital is only part of the offer. Founders also get introductions into corporate buyers, policy networks, and later-stage investors who understand transition markets. That matters in climate tech, where the first customers are often industrial or public-sector actors, not consumer apps. Fund I launched in 2018, deployed about $30 million, and produced multiple exits. Fund II targets about $200 million after a reported $70 million first close, and continues the same "capital for systems change" mandate. Core themes stay consistent: sustainable food and materials, clean transport, climate intelligence and finance, and climate restoration (including removals and biodiversity-linked work). For directory readers, Systemiq Capital is useful when a company needs more than a generic climate VC. If the product only works when industry rules, procurement, or infrastructure shift, this is a firm that underwrites that complexity on purpose.

Vodafone Foundation is an independent UK charity associated with Vodafone and principally funded by Vodafone Group Plc. The foundation reports more than 30 years of activity and is governed by a board of trustees. It connects Vodafone's charitable giving, technology, connectivity, employees, and market presence with specialist partners. Country-level Vodafone foundations and programs may be separate local entities, so this profile describes the group foundation rather than collapsing every national organization into one legal body. Its current strategy has three global challenges: digital learning and inclusion; tackling harm and abuse; and resilience and response in times of crisis. Programs include digital education for refugees and young people, digital confidence, technology supporting survivors of domestic abuse, maternal-health referral and transport systems, emergency communications, and crisis-response tools. Some support is cash, but much of the model is co-designed technology, connectivity, employee expertise, and long-term program delivery; these in-kind and operational contributions are not equivalent to grants. The foundation says it is not a traditional grant funder and does not respond to unsolicited funding requests. It instead builds long-term partnerships with shared responsibility for design, delivery, evaluation, and innovation. The reported goal of improving 300 million lives by 2025 is an organization-defined aggregate claim, not a count of grants or independently verified causal outcomes. No broadly applicable cheque range or open application route is published.

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.
