About Day One Ventures
Day One Ventures is a San Francisco venture capital firm founded in 2018 by Masha Bucher, investing in startups and then leading their communications. The firm backs early-stage companies with customer obsession in their DNA and works to accelerate mass adoption of the technologies they create, harnessing storytelling, art and culture. It invests from pre-seed and seed through Series A and later rounds across AI, fintech, climate and energy, enterprise, future of work, consumer, deep tech and web3.
The communications work is the product: Day One charges portfolio companies nothing for public relations, staffs the function full time, and has built a record of tier-one launches for its companies, which is why one trade profile described it as the venture capital firm that charges $0 for PR and has twelve unicorns to show for it.
Three funds have been raised, with Fund I at $19.18 million, Fund II at $52.55 million, and Fund III announced at $150 million. The portfolio listed on the firm's own site includes World, the identity network led by Alex Blania and Sam Altman; You.com, Richard Socher's controllable AI search engine; Remote; DoNotPay; Orchid; Artisan; Symbolica; Regie.ai; Moonhub; CalypsoAI; Wordware; Netic; and Filed.
Management teams at those companies point to press launches, executive hiring and customer introductions as the firm's contribution rather than governance, and Day One runs founder dinners and offsites to keep that community connected.
