Our take

Harmonic is working to build Mathematical Superintelligence (MSI), delivering AI for formal mathematical reasoning. This has a worth of potential uses, from improving how maths is taught in schools to accelerating the advent of verified software synthesis in safety-critical domains.

It's an intriguing prospect which has gained investor attention to the tune of $75M. This funding will support the company's rapid growth as the leader in developing MSI. Most interestingly, when complete, Harmonic's AI will be the first to have mathematical capabilities superior to that of humans.
