Elizabeth Weil brings unusually comprehensive venture experience across seed, growth, operating, platform, and secondary markets—including early-stage at Menlo Ventures, late-stage at IVP, operating roles at Twitter during hypergrowth, market development at Andreessen Horowitz, and secondary investing at 137 Ventures—which she explicitly uses to coach early-stage founders at Scribble Ventures. She frames fund formation as an entrepreneurial act itself and runs Scribble as an extension of the operator-investor playbook she developed with her husband Kevin Weil, combining their joint operating experience into hands-on company-building support rather than just capital.

• Focused heavily on the intersection of artificial intelligence and science, viewing research as the root of future innovation. She actively engages with the business mechanics of building in this sector, warning founders to avoid valuation traps and arguing that speed alone is not a sufficient long-term defensive moat for a company.
• A deep professional and personal alignment with Kevin Weil, who is involved with her fund and holds a leadership role at OpenAI. She frequently bridges their worlds, sharing anecdotes about testing new models together at home—such as asking an AI to predict her personality type—and discussing how his work influences their shared view of the future.
• Values high-velocity execution and tangible momentum in the teams she backs. She frequently praises startups that maintain a rapid shipping cadence, noting that the energy and pace of continuous product launches are key indicators she looks for and celebrates.
• Motivated by a philosophy of techno-optimism rooted in personal experience rather than just financial return. She openly shares that her dedication to technology is personal, citing a specific instance where advanced medical tech saved her premature son's life, which drives her conviction that we need more technology in the world, not less.
• Interested in the practical application of AI tools within investment workflows. She actively asks peers about how they are integrating custom GPTs into their operations and backend systems like Airtable to streamline the venture capital process.
