Former DeepMind researcher David Silver has secured $1.1 billion in record-breaking seed funding for Ineffable Intelligence at a $5.1 billion valuation. The London-based startup aims to build a 'superlearner' AI using reinforcement learning rather than human-generated data, directly challenging the large language model paradigm that currently dominates the AI industry.

Building AI That Learns Without Human Data
Ineffable Intelligence aims to create a "superlearner" capable of discovering knowledge and skills without relying on human data by leveraging reinforcement learning—a technique where AI systems learn through trial and error rather than studying human-generated examples
1
. This approach stands in direct contrast to large language models, which are trained on human-generated internet text. Silver argues that LLMs are fundamentally limited because they can only synthesize and remix existing human knowledge, not discover something genuinely new4
. "Human data is like a kind of fossil fuel that has provided an amazing shortcut," Silver told Wired. "You can think of systems that learn for themselves as a renewable fuel—something that can just learn and learn and learn forever, without limit"5
.Reinforcement Learning as the Path to Achieve Superintelligence
Silver, a professor at University College London who spent more than a decade leading the reinforcement learning team at Google-owned DeepMind, brings exceptional credentials to this ambitious mission
1
. His work on AlphaGo, which defeated 18-time world champion Lee Sedol 4-1 in a match watched by 200 million people across Asia, demonstrated how AI could exceed human precedent in narrow domains4
. AlphaZero, his subsequent creation, mastered Go, Chess, and Shogi from scratch through pure self-play without any human data—the first demonstration that a single reinforcement learning system could achieve superhuman performance across multiple complex games simultaneously4
. AlphaGo's famous Move 37 in Game 2 against Lee Sedol was not in any human game record; it was discovered by a machine reasoning beyond human intuition4

Superlearner AI Through Simulations and Self-Play
Ineffable Intelligence plans to build what Silver calls "superlearners"—AI agents placed inside simulations where they can pursue goals, fail, adapt, and improve without the limits of a static human dataset

. While Silver declined to describe what those simulations would look like, he said the approach would allow agents to collaborate and develop capabilities autonomously. The company's website claims that "if successful, this will represent a scientific breakthrough of comparable magnitude to Darwin: where his law explained all Life, our law will explain and build all Intelligence"1
. Silver describes his mission as "making first contact with superintelligence," stating the company aims to "transcend the greatest inventions in human history, such as language, science, mathematics and technology"3
.London AI Hub Gains Momentum
Incorporated in November 2025, Ineffable Intelligence has no product, no revenue, and no public roadmap

. Yet the $5.1 billion valuation reflects a broader pattern in AI investment where the market values the credibility of the researcher and the tractability of the thesis over current capabilities. The company joins a growing wave of AI ventures founded by star researchers raising massive "coconut rounds"—a tongue-in-cheek escalation of traditional seed rounds. Just last month, AMI Labs, co-founded by Turing Award winner and former Meta AI scientist Yann LeCun, raised $1.03 billion at a $3.5 billion pre-money valuation1
. These companies suggest mounting momentum around London as an AI hub, partly thanks to DeepMind's continued presence after its acquisition by Google in 20141
. Several former DeepMind staffers are reportedly set to join Ineffable's executive team, creating a powerful network of alumni driving innovation in the region1
