Numerai is a quant hedge fund that crowdsources stock predictions from data scientists, paying them in its NMR cryptocurrency.
HN commenters link it for the crypto-paid hedge fund model; one points out its data is obfuscated by a closed-source method, not standard encryption.
Worth pointing out that Numerai actually doesn't use encryption in any standard sense (including structure-preserving encryption), but instead seems to be using some heuristic method of obfuscating their data.
Their (closed-source) method of obfuscating their data apparently does have the property that it preserves the structure of the data, but calling it "structure-preserving encryption" is misleading imo since it risks confusing it with standard notions of encryption and structure-preserving encryption which have much stronger security guarantees.
(Their marketing seems to encourage this conflation by, for example, citing academic advances in standard notions of homomorphic encryption and SPE and implying that these advances have enabled Numerai's technology)
