Most of the 2023 cohort competed on capability; the bet here was on manner. Pi, released in May 2023, was shaped by hundreds of paid teachers — behavioural therapists, novelists, playwrights, even comedians hired to give it a sense of humour — so that it listened and asked follow-up questions rather than completing tasks. It reached roughly a million daily users with sessions averaging over half an hour, and never turned that into a business, which is itself the finding the companion products that followed inherited: warmth buys attention and not revenue. The infrastructure work travelled further. A cluster co-developed with CoreWeave trained the MLPerf GPT-3 benchmark on 3,584 H100s in under eleven minutes in June 2023, evidence that a startup barely a year old could reach frontier training scale on rented GPUs rather than owned data centres. The company was also one of the seven signatories to the White House voluntary commitments that July, sitting beside Amazon, Google, Meta and Microsoft with no meaningful revenue. The mark that outlasted the products is structural. When Microsoft paid about $650 million to license the technology in March 2024 and hired the founders and most of the seventy staff without buying anything, it produced a shape — large payment plus mass hiring, arranged to sit outside merger notification — that Amazon and Google reproduced within months. Britain's competition regulator cleared the arrangement in September 2024, and the argument over whether such deals should be reviewable is still running.
