Alex Halliday started building fan sites at 13, grew them to about 30 million monthly page views, later became the youngest CEO of a company listed on London's AIM at 25 through SocialGO, and was MasterClass's first product hire, helping scale it from roughly $5M to $100M+ ARR, before making early investments in OpenAI, Anthropic, Groq, and Discord as a Venture Partner at SparkLabs Global Ventures. Shaped by watching ad rates collapse from $12 to $0.60 on his teenage site, he now focuses on content engineering, treating a company's support transcripts, product usage, and sales calls as the real material for good content, and he's known for following actual user behavior, like the product usage patterns that drove AirOps' pivot, over theory, while pushing back on AI hype in favor of hands-on experimentation.
