As the founder and former CEO of Gliffy, I pledged 5% of our company's profits to a donor-advised fund and granted the product to nonprofits. Following the company's sale, I committed significant proceeds to continue this work.

Two experiences shaped my philanthropic focus: converting my San Francisco home to zero emissions in 2020, and time spent in California's Sierra Nevada Mountains, which fostered a deep appreciation for forest ecosystems.

I was interviewed about my approach to climate philanthropy in the Aspen Institute report Funding Climate Action: Pathways for Philanthropy.

Impact Investing

Beyond philanthropy, I invest in companies developing solutions to eliminate CO2 emissions and accelerate the transition to clean energy. My focus is on early-stage companies with technologies that can scale to make a meaningful impact on climate change.
