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.

Unlocking the Next Generation of Lithium-Ion Batteries

For over 30 years, lithium-ion (Li-ion) batteries have dominated the battery market due to their high energy density and reliable performance. Today, the global Li-ion battery market stands at $100 billion and is projected to surpass $500 billion by 2035.

While incremental advancements have improved energy and power density, the core design and manufacturing processes of Li-ion batteries remain largely unchanged since their inception. Current manufacturing is highly energy-intensive, involves complex process steps, carbon-intensive, and dependent on specialised labor.

This has created significant barriers to entry for battery startups, particularly in Europe, where scaling from pilot to mass production is fraught with cost and efficiency challenges.

We are reimagining the Li-ion battery platform from the ground up—delivering breakthroughs in performance, safety, cost, and sustainability while drastically simplifying manufacturing.

The Opportunity

We have developed a novel Li-ion battery manufacturing platform that slashes costs, accelerates production, and dramatically reduces environmental impact:

• Over 30% lower cell costs per kWh due to a streamlined manufacturing process, shorter production lead times, and a 50% reduction in CAPEX and manufacturing footprint.
• 70% reduction in greenhouse gas emissions, achieved through process simplification and a high-efficiency direct recycling approach. This platform enables an 80% battery material recycling rate, cutting lifecycle emissions by 56%, with an additional 14% reduction from optimized process steps.
• 30% higher energy density, unlocking performance gains that conventional Li-ion cell structures cannot achieve. Improved safety and power capability are also inherent to our optimized design.

Our technology transforms the economics and sustainability of Li-ion battery production, unlocking its full potential to meet the evolving demands of electric vehicles, grid storage, and beyond. We are currently designing the first prototypes and preparing for real-world performance validation.

We are looking for a CEO and Co-Founder. Your role will be broad, across product, sales, partnerships, operations, fundraising (venture and non-dilutive), team building, supplier management, and industrial scale-up. You will drive commercialisation and market adoption alongside a cutting-edge technical team poised to redefine the Li-ion battery industry.

You will join a stellar CTO & Co-Founder, a battery industry insider whose career has spanned from doing a PhD at University of Tokyo, to being the first hire at a Korean solid state battery company, to most recently leading the tech scouting and R&D efforts at a major European battery manufacturer.
