Background
About James Isilay
A technical CEO and entrepreneur, I specialise in building and scaling high-growth tech companies at the intersection of AI, SaaS, and data-driven go-to-market strategy. With a background in engineering, quant trading, and enterprise software, I bring a deep technical foundation to leadership, combining strategic vision with hands-on expertise. I founded Cognism, transforming it from a bootstrapped startup into a global SaaS leader, scaling revenue from $0 to $80M+ ARR and growing the team to 500+. Now, I’m focused on Agentic AI and emerging technologies, while remaining actively involved in the SaaS ecosystem—both as an investor in high-growth B2B software companies and a board advisor on AI-driven revenue analytics, strategic growth, and corporate governance. Beyond tech, I’m passionate about film and cinema, most recently helping to produce the Berlin Film Festival award-winning film Last Swim.
