Numerai never did a token sale, but people have its token and they are using it.
The numeraire (NMR) was launched in June 2017 as an early departure from the initial coin offering (ICO) template. Now, with the final upgrade of the company's smart contract on ethereum, the maximum supply of tokens will drop from 21 million to 11 million, and the company will throw away the keys to the contract controlling its supply.
"We are going to be decentralized as fuck," Numerai founder Richard Craib told CoinDesk in an interview.
