Press release – Carbon Waters Announces Successful €2 Million Funding Effort

Press release – Carbon Waters Announces Successful €2 Million Funding Effort Carbon Waters 26 April 2023


The French start-up Carbon Waters, specializing in the development and production of lines of high-performance industrial additives, announces it has raised 2 million euros. Recognized by BPI France and France Industrie as a decarbonization start-up in the materials category, Carbon Waters is ramping up its industrial production with a new pilot factory. 

This year the Bordeaux start-up has reached a new milestone in its development with the announcement that it has raised 2 million euros in its latest funding round to industrialize its graphene-based high-performance additives production process.

Building of a pilot factory to scale up graphene production

Achieving this new level demonstrates the great potential of its graphene, a nanomaterial that helps develop products offering a wide range of functions. Graphene has been known for its mechanical and thermal resistance and electrical and thermal conductivity for 20 years. It also offers excellent anticorrosion and preservative properties.

Carbon Waters’ unique dispersed graphene production process is at the heart of its disruptive innovation. The process allows the company to provide industrialists with “ready to use” product lines. Four years of R&D and €3 million of investment in the process have already produced two patents, with a third one on the way.


We are currently working in three major development areas: Our first field of expertise is totally or partially replacing toxic products, particularly for paint manufacturers. Our second field of action: decarbonizing the industry and lightening structures for the naval, automobile, aeronautics, and space industries. Our third area of research: developing solutions for storing and transporting hydrogen, and extending the useful life of materials, such as those used in batteries. Alban Chesneau CEO of Carbon Waters


The start-up will use the investment to advance from prototyping to the preindustrial process. The funds came from Aquiti Gestion and NACO (Nouvelle-Aquitaine Co-investissement), longtime shareholders, and the Tirésias Angels and Paris Business Angels investment funds, plus several other business angels. Carbon Waters also received financial support from Bpifrance.

The funding will initially finance a pilot factory, whose goal is to be the standard-bearer in ultra-low resource consumption in its processes. The new building, to measure approximately 1200 m2, is expected to take shape over the next few months in metropolitan Bordeaux. The company is implementing a sizeable hiring plan to support its development, creating a dozen skilled jobs.

Carbon Waters currently produces 500 kilos of graphene dispersion. The performance of its additives has been validated by numerous firms representing multiple industrial sectors. The company aims to increase its production tenfold next year, with a goal of producing 50 to 100 tons of graphene dispersion by late 2025. Achieving this ramp-up will require a larger-capacity factory and a larger business team. Its new industrial horizon means another round of fundraising.

The company has two main markets in its sights: paints, which account for potentially €2 billion, and polymers, which could exceed €4 billion. Carbon Waters is sealing multiple technological, industrial, and commercial partnership deals with the leaders in these sectors in order to turbocharge market penetration in France and internationally.

About Tiresias Ventures

Tiresias Ventures is an investment club that supports disruptive technologies to ensure sustainable transformation in the agriculture, energy, and industry sectors. We invest amounts of €200K-€500K and we work alongside entrepreneurs to speed the transition from innovation to a marketable industrial technology.

We decided to invest in Carbon Waters because we are convinced that industrial transformation will be achieved by adopting new, more advanced materials to replace toxic elements and components with a large carbon footprint. Graphene has enormous potential in this area, with numerous possible applications in fields such as automobiles, aeronautics, space, construction, batteries, and electronic devices. After devoting several years to R&D, Carbon Waters has demonstrated two important keys for success: its ability to produce high-quality graphene on a large scale, and the interest of market stakeholders, which was underscored by signing its first commercial agreements. It is rare to find start-ups capable of becoming the global standard in their field, but we have identified this potential in Carbon Waters.
