Join us to build a venture securing the future of electrification by scaling the next-generation of battery materials manufacturing. We are seeking applications from experienced industry or startup professionals with deep commercial domain expertise and a keen interest in founding and scaling an impact driven, high growth company from the ground up.

The Opportunity Deep Science Ventures and Prosemino are building a new climate tech venture to eliminate graphite anode material supply as a critical bottleneck to global electrification.

Synthetic graphite anode underpins lithium-ion batteries - and today its production is:

• 95% concentrated in China

• Extremely energy-intensive (:11 MWh per tonne)
• Slow, polluting, and geopolitically fragile

We are building a fundamentally new synthetic graphite manufacturing process that dramatically reduces energy intensity, accelerates production rates, and enables geographically flexible supply. The ambition: make graphite anode material cheaper, cleaner, and scalable enough to keep up with battery demand.

We are now seeking a Commercial Co-Founder to partner with our technical founder and take this venture from formation through Series A and beyond.

This is a ground-floor opportunity to build a company at the centre of the energy transition, addressing a material already shaping trade policy, industrial strategy and global conflict.

Location: UK

Commitment: Part-time initially → Full-time post venture incorporation and spin-out (target Q3 2026)

Equity: Meaningful founder equity + competitive salary post-incorporation

The Role As Commercial Co-Founder, you will own the venture's commercial strategy and execution from day one.

Working hand-in-hand with the technical founder, you will:

• Validate market demand and define target segments
• Build early customer, supplier, and strategic partnerships
• Secure commercial proof points (LOIs, MOUs, offtake pathways)
• Lead fundraising from pre-seed through Series A
• Shape pricing, go-to-market strategy, and long-term commercial positioning

This is a deeply hands-on role. You will personally develop customer relationships, negotiate early agreements, and help to build financial and techno-economic models. As the company grows, you will recruit and lead the commercial function.

Requirements Must-Have Experience:

• Previous experience in either a startup/early-stage company environment, or leading commercial scale-up in a relevant industrial setting (or both)
• A track record in fundraising from venture capital, grant writing, grant management and building commercial partnerships
• Exposure to regulatory processes for industrial chemicals/materials (ideally battery-related)
• A strong network across relevant industries such as electrode/cell manufacturing

Essential Capabilities:

• Lead customer discovery to identify and prioritise target markets, building relationships from initial outreach through to binding offtake agreements, and refining value proposition based on market feedback
• Identify and secure feedstock supply partnerships with petrochemical/coal/other amorphous carbon suppliers
• Co-develop and maintain techno-economic models, pricing strategy and financial models with the founding team, and lead commercial negotiations and contract structuring

Valuable "Nice-to-Haves":

• Experience managing customer application testing programmes, developing go-to-market strategy, and assessing partnership structures including distribution, licensing, and joint development
• Ability to scope and manage regulatory pathways, coordinate with consultants and certification bodies, and substantiate environmental claims
• Understanding of graphite, batteries, or materials industry dynamics

Benefits Joining a world-class team This venture is a collaboration between Deep Science Ventures and Prosemino.

Deep Science Ventures is a leading deep-tech venture studio with a portfolio of 50+ science-led companies at a total valuation of :$500m.
