011h uses technology and timber to make buildings more sustainable
Recommended by: Marc Sabas, Ship2B Ventures
Relationship to VC: Not in portfolio
Founded: 2020
Headquarters: Barcelona, Spain
Total raised: 35 million euros ($36.8 million)
What it does: 011h uses timber, sustainable design techniques, and software to build affordable and environmentally-friendly homes quickly.
Why it’s poised to take off: The built environment accounts for 39% of annual carbon emissions, from the energy a building takes to operate to the emissions generated when producing the building materials. As a result, sustainable housing often comes at a higher price and this hinders scalability, Sabas said. It also makes the sector particularly hard to decarbonize.
“011h tackles the problem holistically by bringing together suppliers, builders, planners and developers in a single platform that integrates all components in building, reduces project management time and has the ability to measure end-to-end the embodied carbon in a new building,” the investor said.
The company also has seasoned founders in Lucas Carné and Jose Manuel Villanueva, the previous cofounders of Privalia, a flash sales company they exited and one of Spain’s early success stories.
