U&I Ventures has closed an oversubscribed debut fund with $32.237 million in commitments to invest in seed-stage companies building AI-native infrastructure across security, engineering, and information technology.
The San Francisco-based venture firm was founded in 2025 by Kim Moore and is built around a community of approximately 1,800 enterprise technology leaders.
Its network includes nearly 650 CISOs and security executives, around 850 CTOs, and more than 300 CIOs.
U&I uses feedback from these executives to identify technology gaps, assess potential investments, validate products, and introduce portfolio companies to prospective customers.
Fund I plans to invest in 40 to 45 pre-seed and seed-stage businesses, with initial checks ranging from approximately $250,000 to more than $800,000.
The firm has already completed nine investments across AI security, agent reliability, enterprise infrastructure, and compliance.
Portfolio companies include Pluto Security, which has raised $42 million across two financing rounds, and ZeroDrift, which develops systems for monitoring and controlling AI-related compliance decisions.
Seven additional investments remain in stealth and focus on areas such as autonomous vulnerability remediation, digital forensics, identity management, security operations, production testing of autonomous AI agents, and AI data infrastructure.
U&I said its network can provide founders with rapid access to potential enterprise users. The firm connected Pluto Security’s founder with 68 enterprise CISOs in less than 24 hours during its seed financing process.
Moore previously spent more than a decade at Glynn Capital and Innovation Endeavors and invested in enterprise infrastructure businesses including Chronosphere and Drata.
The firm’s model is designed to bring enterprise buyers and operators into the investment process early enough to help startups shape products around real operational demand.
