Avesta Fund is a certified B Corporation venture capital fund that invests 100% of its capital in early-stage tech startups whose business models are intrinsically tied to decarbonization and economic opportunity, with an explicit screen that rejects any deal where impact is not core to the product or revenue engine. The fund systematically prioritizes founders from communities most affected by climate change and inequality, operates as a public-private bridge through its partnership with Colorado's Venture Capital Authority, and combines traditional venture returns with formal impact verification using standardized frameworks.
