Alex Sherman
Alex Sherman is the CEO and co-founder of Bluefish, a New York-based platform that measures and shapes how brands appear in answers from ChatGPT, Gemini, Claude, Perplexity and Amazon's Rufus. A European history major who became one of MediaMath's earliest employees in 2008, he co-founded the retail-media platform PromoteIQ (acquired by Microsoft in 2019) before launching Bluefish in 2024 to rebuild the marketing stack for the AI internet. In April 2026 Bluefish closed a $43M Series B co-led by Threshold Ventures and NEA, bringing total funding to roughly $68M, with around 10% of the Fortune 500 already on the platform.
