Page One Ventures

Page One Ventures is an early-stage Silicon Valley venture capital firm founded in 2020 by General Partner Mo El-Bibany and headquartered in San Francisco. The firm invests in software transforming existing markets and in deep technology creating entirely new ones, with stated focus areas in life sciences, deep tech, and B2B SaaS, with particular emphasis on data infrastructure and AI. Its thesis, captured in the firm's own phrasing, is that the future will be 'written in code and in codons,' reflecting a deliberate barbell between software and biology or hardware frontiers. The team of seven spans the United States and United Kingdom, with Venture Partners Ameena El-Bibany and Marc-Alexandre Saba complementing the founding GP. Through prior funds, the partners have backed more than 50 companies that have gone on to raise more than $1.5 billion in follow-on financing at an aggregate enterprise value exceeding $20 billion. As of October 2025, the Page One portfolio numbered approximately 68 companies across seed and Series A, including five unicorns and five acquired companies. Headline names include Dapper Labs, DataRobot, Ayar Labs (which reached unicorn status in 2024), and Portal Biotechnologies. The most recent reported new investment is GRO Biosciences in July 2024, and the most recent exit was Teampay, acquired by PayStand in April 2024. Page One takes a conviction-driven, founder-centric approach, deploying across both pre-seed and seed stages. The firm's interdisciplinary perspective across software and life sciences allows it to evaluate companies at the intersection of biology and computation that generalist funds may be poorly positioned to underwrite.
