[AI Startup Ineffable Intelligence Completes $1.1 Billion Seed Round Financing, Valuation Reaches $5.1 Billion] According to Golden Finance, on April 28, AI startup Ineffable Intelligence, founded by former Google DeepMind core researcher David Silver, announced the completion of a $1.1 billion seed round financing, setting a record for the largest seed investment in European history. The company, established at the end of 2025, completed this round of financing within just a few months of its founding, with a valuation reaching $5.1 billion. This round of investment was co-led by Sequoia Capital and Lightspeed, with participation from NVIDIA, DST Global, Index Ventures, as well as Google and the UK Sovereign AI Fund, among others. Ineffable Intelligence will focus on reinforcement learning technology, which enables AI to learn through its own experiences rather than relying on human-provided data for training. This approach contrasts with the majority of mainstream AI models currently based on training with web text and is seen as a critical direction toward achieving higher-level artificial intelligence.
