FireHOLÂ Project
Summary
🤩
RockstarCosta Tsaousis is a serial founder and technology executive with three decades of experience launching internet businesses, from early ISPs and OSS/BSS startups to cloud hosting, fintech, and modern observability. He is the founder and CEO of Netdata, driving an open-source-first approach to simplify infrastructure monitoring, and also maintains long-running open projects like FireHOL. Costa blends hands-on engineering roots (building C/C++ web systems in the 1990s) with C-level operational leadership across product, technology and business functions, including as COO of Viva Wallet. Based in Redwood City, he leverages deep systems and networking expertise to turn complex infrastructure problems into pragmatic, user-focused products. A hint of his pragmatism: many of his ventures began by packaging technical services for everyday users (e.g., boxed ISP subscriptions), showing a consistent focus on accessibility alongside technical innovation.
