Outlier Build
Green construction, building materials and infrastructure
Reshaping how we build: innovative materials, energy-efficient design and smart construction technologies, and green building projects developed to the standard investors fund.
OUTLIER PROPEL · VENTURE BUILDING LAB
Climate venture development, one sector at a time. We bring startups and corporates together to turn climate solutions into investable businesses, and every cohort ends with investors and buyers, not a trophy.

WHY SECTOR-FOCUSED
Founders often have a product, but no proof customers will pay, numbers that don’t add up, and documents investors won’t accept. Those gaps, and the fixes, differ by sector. So each pathway focuses on one.
Construction, food, energy, transport and manufacturing each need their own solutions.
The corporates in each sector help adopt, buy and scale what startups build.
A mini-grid and a food business are financed differently. We prepare ventures for the money that funds their sector.
Where we’re strongest: over half of our venture pipeline is in renewable energy and agri-food.
THE SIX PATHWAYS
Every pathway follows the same proven journey, with sector-specific experts, investors and buyers.
Green construction, building materials and infrastructure
Reshaping how we build: innovative materials, energy-efficient design and smart construction technologies, and green building projects developed to the standard investors fund.
Agriculture, agribusiness and food systems
Changing how we produce food: productive use of energy, digital platforms that cut food waste, lower-carbon fertilisers, and businesses that reduce post-harvest losses.
Renewable energy, power and electricity access
Clean power for homes and businesses: solar, mini-grids and other renewable energy solutions that widen access to reliable electricity.
Manufacturing, recycling and circular economy
Sustainable production and packaging: waste reduction, recycling and circular business models where waste is minimised and resources are maximised.
Electric mobility and clean logistics
Moving people and goods with lower emissions: electric vehicles, sustainable logistics and intelligent transport systems.
Extractive industries and natural resources
For businesses in mining, natural resources and the services around them, building responsible, investable operations.
