James Green grew up in Redditch, a small industrial town in the UK, and broke into venture capital through cold emails, which he now uses as an example for founders about creating their own luck rather than waiting for warm introductions. He focuses on cybersecurity and fintech at CRV, combining those domains as a differentiated lens, and spends unusual time helping early technical teams with security fundamentals like logging and incident response readiness.

• Deep interest in artificial intelligence, security operations, and infrastructure software. This is evident in the enthusiasm for companies like Lotus, which is described as potentially having a life-changing impact comparable to the launch of ChatGPT, as well as a proclaimed affinity for infra and cyber sectors.
• Investment philosophy centered on high conviction and ownership concentration rather than broad diversification. Tweets suggest a strategy of writing large checks early to secure significant ownership, explicitly rejecting the approach of making small checks just to spread risk, and noting a recent decision to double down on portfolio company Vega with a massive individual check.
• Geographic preference for San Francisco and Tel Aviv. Frequently champions the Bay Area ecosystem as superior despite logistical complaints about Highway 101, while also maintaining active ties to the Israeli tech scene through visits to Tel Aviv for events like Cybertech and partnerships with local groups.
• Appreciation for speed and decisiveness in deal-making. Recently noted a personal record for the fastest investment decision ever made and discusses the nuances of professional introductions when speed is a factor, alongside sharing updates about sending out multiple term sheets early in the year.
• Active celebration of portfolio successes and team milestones. Consistently amplifies news regarding acquisitions, such as those involving Cyera, and welcomes new founders to the firm, framing the relationship as a long-term partnership that requires mutual belief.
