About Marble

Stealth is a Marble Portfolio Company. Marble is a climate tech venture studio. We partner with scientists, engineers, and operators to create companies solving hard climate problems in the world's largest industries. Our first 11 companies are building transformative products across energy, industry, agriculture, and climate resilience. 100% have been successful in raising follow‑on to date. We are looking to partner with exceptional individuals to create our next venture.

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.

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.

CEO and Co-Founder

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 Ph.D. at the University of Tokyo, to being the first hire at a Korean solid state battery company, to advancing R&D efforts at a major European battery manufacturer (Northvolt) as one of the first hires for over 8 years.

Requirements

We are looking for an entrepreneurial individual highly motivated to start their own business from scratch and a driving motivation to mitigate climate change. The ideal candidate has demonstrated experience and/or potential in CEO type activities, prior experiences in commercialisation of early‑stage technologies, and outstanding communication skills for partners & stakeholders engagement. Additionally, we are looking for a CEO who is just as excited as we are about e‑mobility & Li‑ion battery industries and eager to re‑localise battery manufacturing to Europe.

We’re primarily looking for someone in Sweden, France, or Germany (or willing to relocate).

Example of relevant backgrounds:

• Former startup founder / operator / VC - with a deep tech, hardware & ideally battery or adjacent technology focus
• OR commercial operator at a major battery company, specialised across the battery value chain, from sourcing battery inputs to manufacturing battery cells to negotiating offtakes.
• OR infrastructure leader, with extensive project finance and project development experience, able to think strategically about building a gigafactory with smart capital

We encourage you to apply even if you don’t feel you meet all the requirements. Above all, we value intelligence, creativity, and Founder Potential.

Especially if you recognise yourself below:

• You can’t wait to start your own company (or your next one)
• You are a pragmatic optimist on a mission to tackle climate change
• You are outcome focused and action oriented - you make things happen
• You are a great communicator - you can convince others to follow you
• You love to break down ambitious goals into actionable milestones
• You understand that innovation starts with people - not ideas

What We Offer

We offer (among other things):

• A competitive salary
• A significant share allocation.
• Full‑stack support from Marble's existing investors and network
• Mentorship and guidance at every step of the way
• Access to an unparalleled network across science, industry, talent, investors, mentors, and other climate deeptech founders
• Seed Fundraising support Introductions to the best seed investors and help with term sheet negotiation.
• Relocation support to target geographies: France, Sweden, or Germany.
