About Marble

Marble is a climate tech venture studio. Our north star is to erase billions of tons from annual greenhouse gas emissions and create a thriving future.

We partner with scientists, engineers and operators to create new deep tech companies that solve hard climate problems — slash emissions, remove carbon from the atmosphere, and cool the planet — while reshaping multi-billion $ industries.

We're proud to be backed by leading climate investors across Europe and the US.

Closing the Copper Supply Gap

Achieving net zero requires the deployment of clean energy technologies at a speed and scale that has no historical precedent. In the transition from fossil fuels to electrified systems, the supply of critical minerals is an acute bottleneck.

Securing a stable and reliable copper supply is a top priority as it is the backbone of electrification in power grids, solar, wind, electric vehicles, and more.

As such, numerous studies forecast copper demand to double by 2050 reaching 57 million tons compared to the 2020 levels of 25 million tons. To meet increased demand, we will need to double our production capacity. However, primary copper production is actually expected to decline as soon as 2028.

With an expected copper supply gap, Europe faces a net deficit between its copper demand and its smelting and refining capacities. To address this, Europe must secure a reliable supply of recycled copper and relocate its copper production industry to achieve self-sufficiency.

We have been working on an innovative process to solve this problem.

The Opportunity

We have developed a wire forming process that produces high conductivity wire without the need for 99.95% pure copper feedstock. This approach eliminates the smelting and refining step, reducing the overall cost of the copper wire production cycle by more than 50%.

Our approach also unlocks several million tonnes of copper scrap that is not currently usable for electrical applications. As a result, it has the potential to transform electrical wire production by maximising the use of recycled copper.

We started to address market and technical risks: a first prototype is on the way, process modelling has been carried out based on proxies found in the scientific literature, an intellectual property strategy has been selected and we have an LOI from a major OEM.

Our work builds on our CTO's PhD research and combines the latest techniques in materials science and metallurgy.

We are looking for CEO and Co-Founder. Your role will be broad, across product, sales, partnership development, operations, fundraising (venture capital and non-dilutive), team building, supplier management, industrial scale-up, etc.

You will join a stellar CTO and Co-Founder, with a PhD in Mechanical Engineering applied to mineral processing and wire manufacturing, and past founder experience.
