Emmanouil Koukoumidis
Emmanouil 'Manos' Koukoumidis is the CEO and co-founder of Oumi (Open Universal Machine Intelligence), a Seattle-area public benefit corporation building what he calls AI's 'Linux moment' - an unconditionally open platform where data, code, model weights and training recipes are all transparent and reproducible. A Princeton PhD who scaled Google Cloud's PaLM with a 300-person virtual team before it became Gemini, and who earlier built emotionally intelligent chatbots at Microsoft, Manos left big tech to give researchers and the wider world the truly open AI he believes they deserve. Oumi raised a $10M seed in early 2025 and launched its commercial custom-model platform in 2026.
GPTZero
GPTZero is a New York-based AI startup that builds tools to detect AI-generated text and verify human authorship. Launched in January 2023 by Princeton senior Edward Tian, it grew from a viral side project into a profitable company serving over 10 million users and 100+ organizations across education, hiring, publishing, and legal. Its mission is to restore trust and transparency to writing on the internet as large language models flood it with machine-made text.
