What Day One Ventures does

Day One Ventures is a San Francisco-based venture capital firm founded in 2018 by Masha Bucher that manages $450 million in assets across multiple funds. The firm invests in early-stage companies from pre-seed through Series A across sectors including AI, fintech, climate and energy, enterprise, future of work, consumer, deep tech, and web3. Notable portfolio companies include world.org (co-founded by Sam Altman), Remote, You.com, Artisan, Valar Atomics, Superpower, and Tivara, with the firm claiming 12 unicorns and over $250 billion in cumulative portfolio value.

Day One's defining feature is its integrated venture capital and communications model: alongside equity capital, the firm provides portfolio companies with hands-on public relations, media-relations, and marketing strategy support from a full-time in-house communications team led by a Head of Communications. Founder testimonials reference direct tier-one media placements in outlets such as WSJ, CNBC, Forbes, Fortune, and The Today Show, as well as introductions, talent support, and fundraising advisory. The firm complements these services with an active founder community built around immersive offsites and intimate founder dinners.

The firm operates with 11–50 employees and generates returns through management fees on committed capital plus equity stakes in portfolio companies. In 2025 it announced Fund III of $150 million and participated in at least nine new investments, including co-leading Valar Atomics' $130 million Series A in nuclear energy. A documented reputational consideration is founder Masha Bucher's prior publicist relationship with Jeffrey Epstein in 2017, for which she has publicly apologized.
