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 deeptech companies that solve hard climate problems — slash industrial 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.

Methane is a very special greenhouse gas. Although it remains only 10 years in the atmosphere, its warming impact is 85x as high as CO2 on a 20-year time scale. Overall, it accounts for a third of the global temperature increase since the industrial revolution.

Rapid methane abatement is the biggest opportunity to mitigate near-term warming and prevent the triggering of dangerous climate tipping points.

Enteric fermentation alone accounts from 30% of anthropogenic methane and 10% of greenhouse gas emissions. This digestive process occurs in the rumen, the stomach of ruminant animals (cattle, sheep, goats).

Various mitigation strategies have been proposed. Feed additives like 3NOP, bromoform, and seaweed can partially tackle enteric methane in feedlots, about 10% of cattle population. Capture systems could be a useful yet marginal solution. Methanogen vaccines would be transformative, but commensal microbes are proving insanely hard to deactivate.

Today no solution combines very high (>80%) abatement rate, cost effectiveness, scaleability across geographies and agricultural systems, and safety, let alone positive increases on animal productivity.

We are exploring novel approaches which could tick all these boxes.

We believe that microbiome interventions could stabilise the rumen in a state that does not emit methane in the first place. Hydrogen redistribution could provide the added benefit of increased animal productivity, but other levers could also be explored, such as methanotrophs, anaerobic fungi, antimicrobial peptides, and microbial cocktails.

Delivery mechanisms would have to be carefully considered to optimise costs, ease of delivery, regulatory approval and compatibility with farmer practices.

We are looking for a Founder in Residence to join our next cohort starting end November 2023, explore these approaches further and create the most scaleable company to slash enteric methane.

We are looking for an entrepreneurial scientist with PhD-level technical expertise related to the rumen microbiome (or microbial ecology more generally).

Examples of relevant backgrounds:

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

Especially if you recognise yourself below:

As a Founder-in-Residence, you will join stellar individuals who also believe in the need for deeptech solutions to solve hard climate problems.

Together, we would be scoping high potential approaches before converging on the most promising one and finding your future co-founders

We offer (among other things)

We are currently taking applications for the November 2023 cohort and we are interviewing on a rolling basis so we encourage you to apply as soon as possible!

We believe that a diverse group of minds is key to solving the climate crisis. We encourage women and people of colour to apply.

Studies have shown that under-represented candidates are less likely to apply unless they feel they meet every single qualification. If you are excited about the opportunity but your experience does not align perfectly - we encourage you to apply anyways.

We are committed to a diverse, inclusive and mission-driven Founder community.
