At One Ventures

We have two types of offerings. Colbridge Growth is for firms that are at seed stage or beyond and seek to scale. We act either as consultants for specific growth-focused projects or as interim execs to execute longer-term remits. We focus on all commercial aspects of early stage businesses - including market understanding, licensing strategy, business development, sales growth, marketing mix, financials, and fundraising. If funding is sought we can also make select investor introductions through an extensive international network. We act as a management consultant, business development professional, and investment banker, all rolled into one. This is ideally suited to the needs of young growing technology-based businesses, who are often short of time, staff, and money. Colbridge Studio is a venture studio for very early stage startups that are looking for a commercial partner to help develop their business. We act as a commercial co-founder, providing the mature entrepreneurial and commercial guidance to help founders get the company off the ground. We invest up to $30k ourselves and can help fill out angel or pre-seed funding needs through an extensive investor network. What we believe We believe that we are at a critical juncture in humanity's journey where environmental disaster and massive social upheaval will occur if we don't act quickly. Business and technology can provide some of the answers. We are seeking similarly mission-driven entrepreneurs to partner with. Here are some of the areas that particularly interest us: GHG Emissions Reduction: This is the defining crisis of our time. Projects to help reduce carbon in the atmosphere and to mitigate its effects are desperately needed. This includes arenas such as renewable & alternative baseload power, circular economy, hydrogen, bioplastics, alt foods, and carbon credits. Water: Water systems are being disrupted by the changing climate. We need ways to clean water, utilize seawater, and generate new sources of freshwater. Regenerative Agriculture: Agriculture has the power to restore the land and water systems that support it. We believe this will be an essential tool to clean the earth while feeding the growing population. New Grid: The massive increase in renewable energy required to meet net zero targets will need an overhauled grid. Energy Storage: One of the key roadblocks to greater penetration of renewables is the limited nature of energy storage. We are looking for technologies to improve the cost, effectiveness, and robustness of energy storage. Metals, Minerals & Materials: Significant increases in volume of key metals, minerals and materials will be required for our changing energy mix. We are interested in technologies and business models for increased supply and reuse/recycling plus the development of new better materials.

The world needs greentech innovations to reach net-zero and circularity, but a wealth of research inventions never gets used at scale. BigCircle Ventures brings a unique flow of early-stage innovations to the market, that would otherwise stay untouched on a shelf, hidden in a university, research institute or company lab. By using a long-proven model for discovering, nurturing and funding, we aim to be the world’s leading greentech venture builder and boost the world’s journey towards sustainability.

Capital for an economy that respects planetary limits. Some generations have built cathedrals. Some have navigated across oceans and expanded the frontiers of the known world. Others have had to rebuild war-torn continents. Our generation’s greatest challenge is equally immense: to create an economic system that respects the planet’s limits, and overcome the ecological crisis. If we are to rise to the challenge, we're going to have to innovate. In a radical way. This means taking risks - carefully considered, never unnecessary, ones. Having the courage to take the long view once again. Rewriting the rules of economic activity from the ground up, by standing alongside those who recognize that the greatest ambition of all lies in finding alternative means to create wealth. Our mission is to support the entrepreneurs who are repairing the world - from the very beginning of their journey, and with no time limit on our commitment. How? By bringing together a broad and diverse community of first-rate investors, and steering the flow of capital to where it is most likely to make a difference. One sector at a time, one start-up at a time, thereby increasing the number of tipping points. Allowing what will save us to thrive in the face of overwhelming adversity. So that we can finally initiate the systemwide transformational change which all of us are calling for, without always knowing where to start.

Climate Change. Plastic Pollution. Water shortages. Planet A Ventures supports founders tackling the world‘s largest environmental problems. We provide early stage funding and mentoring to highly scalable green tech companies – while measuring and forecasting the positive environmental impact of a start-up as our central metric of success. IMPACT FORECASTING We help start-ups to scientifically quantify and predict the positive ecological impact of their business-model. PLANET A NETWORK We give founders access to a unique mentoring network of experienced, serial entrepreneurs, and proven experts. FUNDING We provide early-stage funding to accelerate impact and growth. ENABLE SCIENTIFIC INSIGHT, EMPOWER ENTREPRENEURIAL ACTION We believe in close collaboration of entrepreneurs and scientists to change our economy for the better of our planet. Without scientific insight, even the best entrepreneurs are ignorant of the true ecological impact of their business. This is why we have a full-fledged scientific team committed to calculating Life Cycle Assessments: this allows us to not only evaluate the GHG (greenhouse gas) emissions involved, but also to determine plastic, water, and land use footprints. Our approach provides entrepreneurs with the insight to scientifically quantify, visualize and forecast the environmental effects of their product or service. This knowledge empowers founders to make sustainable and strategic decisions. Such knowledge also allows investors to understand the impact of every Euro they have invested into early-stage start-ups. WITH GREAT POWER COMES GREAT RESPONSIBILITY Our planet desperately needs an economy that operates within its environmental boundaries. This requires us to radically change the ways we produce and consume. Now. Reinventing our economy is a major global challenge. It will take entrepreneurial action, scientific ingenuity, political stamina, and individual choices to achieve it. Capital has great power to influence the future of companies and entire industries: Tomorrow’s economy is based on today’s investment decisions. And we think it’s time for venture capital to take on its responsibility. This is why we at Planet A Ventures work hard to advance an economy that serves the people and our planet. We support start-ups taking action and spearheading positive change with capital as well as knowledge. BY FOUNDERS FOR FOUNDERS Planet A Ventures is founded by founders for founders. Our team and the Planet A Network give every venture unique access to the knowledge and experience of like-minded successful entrepreneurs, scientists, and business experts.

CarbonN Venture Partners is a venture capital firm based in Silicon Valley. Led by two seasoned deep-tech investors with a singular focus to reverse the effects of climate change – accelerating the commercialization and scale-up of breakthrough technologies toward a negative emission economy. We invest in startups late Seed to Series B stage, with initial ticket sizes ranging between $500K and $5M. Further, we will selectively deploy “catalytic capital” to fund First-of-a-Kind (FOAK) projects through project equity or term loans. As part of our investment mandate, we assess a startup’s potential for meaningful climate impact in an analytical and quantifiable way, e.g. megatons of CO2e removed, millions of tons of waste prevented. We will work closely with our portfolio companies to measure and report their own ESG and impact metrics. Thesis Climate disasters like floods, wildfires, snowstorms and droughts are paralyzing supply chains, industries and societies. The sense of urgency as a whole is still not there… To limit global warming to below 2C, carbon reduction technologies are necessary to lower “future” emissions, while carbon removal technologies are needed to lower “historical” CO2 from the environment. These solutions together need to reach gigaton-levels within the next 3 decades. New adaptation technologies such as green infrastructure, water desalination and circular economy solutions also must scale up for industries and communities to adapt and become more resilient to the new climate reality. We believe identifying opportunities with significant social and environmental impacts will lead to better financial return. Investment Areas We invest across a portfolio of carbon negative solutions based on their carbon removal and reduction pathways (Air, Land, Ocean, Rock) augmented and catalyzed by Data and Finance innovations, and Circular Economy solutions in key material markets to improve sustainability and reduce environmental impacts. Air: direct air capture, point-source carbon capture, carbon utilization, waste-to-energy. Land: regenerative agriculture, biochar, forest management, soil carbon sequestration. Ocean: direct ocean removal, electrochemical separation, alkalinity enhancement, seaweed/kelp cultivation, blue carbon. Rock: enhanced rock weathering. mining rocks, geologic sequestration. Data + Finance: wildfire detection, earth observation, remote sensing, carbon accounting, sustainable finance, MRV & ratings. Circular Economy: plastic recycling, battery / e-waste recycling, wastewater treatment, desalination, sustainable packaging. Responsible Investing Better Climate Performance Leads to Better Financial Returns We are committed to responsible investment and incorporating specific ESG considerations into our investment process. We seek to help our portfolio companies to mitigate and manage risk as well as their long-term sustainability. We believe integrating these ESG principles in our investment practice will have a positive impact on the financial performance of our fund.
