DEEPMIND LEGEND RAISES $1.1 BILLION TO BUILD AI THAT TEACHES ITSELF EVERYTHING — NO HUMAN DATA ALLOWED The man who built AlphaGo just raised $1.1 billion to do something the rest of the AI industry is not attempting. David Silver, the former DeepMind research lead whose reinforcement learning system defeated the world’s best Go player, has launched a startup called Ineffable Intelligence with a goal that most people in AI consider either visionary or reckless, depending on who you ask. He wants to build a system that learns without any human-generated training data at all. The seed round, co-led by Sequoia and Lightspeed with participation from Nvidia, Google, DST Global, Index Ventures, and the UK’s Sovereign AI Fund, values Ineffable at $5.1 billion. It is the largest seed round in European history. Silver is not raising money to build a better chatbot. He is raising money to pursue what he calls a superlearner, an AI that can discover knowledge and skills through experience alone, the way AlphaGo taught itself to dominate Go without ever studying human games. Every frontier model today, including GPT-5.5 and Claude Opus 4.7, is built on a foundation of human-generated text. Pre-training on the sum of the internet is how modern AI works. Silver believes that approach is also a ceiling and that the only way past it is to build a system that can reason from first principles through interaction with the world. Nvidia is betting he is right. So is Google, whose own DeepMind trained Silver for over a decade. The round closed at a valuation of $5.1 billion before the company had shipped a single product.
