ABOUT MARBLE Marble https://marble.studio 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 14 companies https://marble.studio/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. EMPOWERING THE TRADES The UK’s 885,000 construction micro-businesses deliver £49bn of small construction projects each year. Most run on WhatsApp, spreadsheets, and memory. The unstructured approach costs roughly 20% of each job in scope drift, rework, untracked changes, and delayed compliance. The industry is also highly wasteful, with 13% of materials never being used, and construction accounting for 61% of the UK’s landfill. We are reliant on this highly fragmented industry to refurbish our buildings to meet performance needs and the targets of the Climate Change Act. However, at current rates, it will take 100+ years to decarbonise the UK’s built environment. We are building an AI-native operating system for independent installers to ease administrative burden, reduce project costs, and accelerate business growth. Our technology empowers tradespeople to grow their business, gain professional independence and administrative efficiency. By de-risking installations for both the contractor and the customer, we will enable cost effective delivery across millions of buildings.
