Founder in Residence - Mineralisation

Company description

Marble is a climate tech venture studio. We partner with scientists, engineers and operators to build deeptech startups that slash emissions, remove carbon from the atmosphere, and create climate resilience.

The climate crisis is the most pressing challenge of our times. We need breakthrough solutions to address hard-to-abate emissions, as available technologies only get us halfway. However, we can’t put all our hopes in classic tech transfer. We need to intentionally create and deploy radical solutions.

As Founders-in-Residence, they work with us on "hard climate problems" and build ventures with massive impact potential.

We invest in the best teams at pre-seed.

Our mission: bring us at least one gigaton closer to net zero and create a future that thrives.

Job description

Hard Climate Problem: CO2 Mineralisation
Mineralisation occurs when certain rocks are exposed to CO2, which binds with calcium, magnesium or other elements to form carbonate minerals. This phenomenon naturally removes 1.1 gigaton of CO2 per year and could be enhanced to multi-gigaton scale by 2050. Mineralisation has three unique advantages: chemical reactions require no energy input, the reactive minerals are in almost unlimited supply, and sequestration into rocks ensure maximum permanence. However, the reaction rate is very slow, the distribution of optimal resources is poorly understood, and certain methods face other challenges across water use, safety, logistics scaleup, and carbon uptake measurement.
We are scoping opportunities to remove these bottlenecks and unlock the gigaton potential of carbon mineralisation. This impact area being relatively unexplored compared to other pathways, we believe that several whitespaces exist for radical improvement.
Potential opportunities:

  • Mapping existing alkaline resources: natural (basalts, peridotites, serpentinites) and human-made (mining and industrial waste)
  • Efficient production and handling of optimised alkaline materials
  • Improving reaction kinetics and mass transfer via process engineering, novel reactors, biological agents, electrochemistry, or other methods
  • Synergies with agriculture (enhanced rock weathering), mining and industrial operations, siting near abundant low-carbon energy
  • Hybrid applications: metal recovery, CO2 utilisation, hydrogen production, etc
  • MRV: sensors and platforms for measurement, reporting and verification of carbon uptake and environmental impacts (esp.T on biodiversity)
  • Scaleable logistics to handle very large material quantities
  • Optimised in-situ mineralisation for CO2 storage
  • Carbon-negative concrete
  • Surprise us!

We are actively looking for new Founders in Residence to join us, either:

  • As First Founders to scope entirely new approaches
  • As Co-Founders for projects in development within Marble

Who We Are (Really) Looking For
We encourage you to apply even if you feel you don’t meet all requirements above. We know that some skills can be learned while you are building!
We value intelligence, creativity and Founder Potential:

  • You dream of founding your own company becoming your own boss, and putting together a great team to accomplish something awesome. 
  • You are a pragmatic optimist with a driving motivation to mitigate climate change.
  • You love to communicate your passion for deeply complex subjects
  • You are self-motivated, action-oriented, and you enjoy working on multiple aspects of a complex project with an interdisciplinary team, in a fast-paced environment.
  • You are naturally inquisitive and curious, anchor on the right concepts quickly, and go deep enough to surface non-obvious insights.
  • You approach radically new ideas with an open mind. You get to the salient questions quickly, and your first instinct is to ask how they scale.
  • You understand that innovation really starts with people, not ideas. You enjoy building collaborations within a team and with external partners.
