Value proposition
Develops AI systems that learn from their own experience through reinforcement learning, aiming to achieve superintelligence by scaling self-learning agents.
Products and solutions
["Superlearner AI system based on reinforcement learning"]
Target customer
Enterprises and researchers seeking foundation models that can autonomously discover knowledge and solve complex problems across science, mathematics, and technology.
Industries served
["Research","Artificial Intelligence"]
Technology advantage
Reinforcement learning-first approach that learns from experience rather than human data, challenging the dominant large language model paradigm; led by world-renowned AI researcher David Silver.
How they differentiate
Focuses on reinforcement learning and self-experience learning as an alternative path to AGI/ASI, unlike most labs that rely on scaling laws and large language models trained on human text.

Major milestones
["Founded by David Silver in November 2025","Raised $1.1B seed round at $5.1B valuation, Europe's largest seed round ever","Launched from stealth in April 2026"]
Market positioning
A frontier AI research lab competing with OpenAI, Anthropic, and DeepMind, but focused on a different technical approach: reinforcement learning over language models.
