Kelci Zile is CEO of Envest, a private community of more than 90 active climate investors working together to accelerate conviction, capital, and deployment. Zile has helped grow Envest for nearly three years and has served as CEO for more than a year. Her superpower lies in connecting the dots, bringing unlikely people together to build high-trust communities and create relationships that unlock capital.

Zile currently invests in early-stage companies advancing future materials, agriculture, and nature-based solutions. She is an advisor to Sound Future, has advised Madrona Venture Labs for the past three years, and serves on the board of the University of Washington’s Buerk Center for Entrepreneurship. Previously, she spent seven years at Amazon, where she built the sustainability category for AWS Data Exchange and AWS Marketplace and served on the Amazon Sustainability Ambassadors Global Board.

Her investment thesis has not changed: to build the future economy, we need to invest in solutions that are better, cheaper, faster, and sexier than the incumbent alternatives.
