John Denniston

Chairman of the Board


John Denniston is Chairman of the Board of Shared-X, an agricultural impact company aiming to both generate profits and lift large numbers of smallholder farmers out of poverty.

Denniston was previously Senior Partner at the Silicon Valley venture capital firm Kleiner Perkins Caufield & Byers, where he co-founded and co-ran the firm’s $1 billion Green Growth Fund, which invests in sustainability companies in their growth stage.

Prior to Kleiner Perkins, Denniston was a Managing Director and Head of Technology Investment Banking for the Western United States at Salomon Smith Barney. He also served on the Investment Committees for Salomon’s venture capital/private equity direct investment fund, as well as CitiGroup’s venture capital fund-of-funds. Earlier in his career, Denniston was a partner with a large law firm, where he was head of the firm’s venture capital practice and co-head of its information technology practice group.

Denniston earned his B.A. in Economics and J.D. from the University of Michigan.
