# Anneli Tostar

> Anneli Tostar is the CEO and co-founder of Tangible, a San Francisco software company that helps real estate developers measure, manage, and cut the embodied carbon locked inside the materials they build with. An Oregon-born, Swedish-heritage urbanist who studied anthropology and environmental policy at Harvard and sustainable urban planning at KTH Stockholm, she spent years inside the commercial real estate sustainability world in the UK and US before deciding the industry's spreadsheet-and-Google-search approach to low-carbon materials needed a real platform. She co-founded Tangible with Nicole Granath in late 2021, raised $8.8M, and is on a mission to make choosing low-carbon materials, in her words, stupidly easy.
