Day One Investments

Day One Investments

Day One Ventures was founded by Masha, who co-leads the firm alongside partner Sanjiv. The firm operates out of New York with additional offices in London, Columbus, and St. Louis, targeting early-stage technology startups globally. Its wealth origin is not publicly disclosed. The firm invests across AI/ML, fintech, climate tech, enterprise software, future of work, consumer, deep tech, and web3 — a broad generalist mandate. Day One differentiates by embedding a communications and PR team into its investment process, helping portfolio companies secure coverage in outlets like Forbes, Fortune, the Today Show, and TechCrunch. Confirmed portfolio companies include tools (unnamed in public sources) and founders such as Richard Socher (CEO of You.com), Alex Blania (CEO of Tools for Humanity), and Joshua Browder (CEO of DoNotPay). The firm participates in seed through Series C rounds, often leading or co-investing. The firm raised $150M for Fund III in 2023 (per TechCrunch, 2023), its largest vehicle to date. The team size is undisclosed. Masha and Sanjiv are the named partners; no other investment professionals are listed publicly. Day One does not appear to operate separate philanthropic or operating-company vehicles. Day One’s structural differentiator is its integrated communications arm — a full-time staff of PR and marketing professionals that works on behalf of portfolio companies as a core service, not a bolt-on. This model, rare among venture firms of its size, positions Day One as both capital provider and in-house agency, a structure that founder testimonials compare to adding a co-founder rather than a check writer.
