Harmonic, a Palo Alto-based AI platform, raised $75M in Series A funding.

Sequoia Capital led the round, with participation from Index Ventures, Era Funds, GreatPoint Ventures, and DST Global partners, among others.

The funds will support Harmonic's rapid growth and development of Mathematical Superintelligence (MSI).

Co-founded by CEO Tudor Achim and Executive Chairman Vlad Tenev, Harmonic’s MSI aims to eliminate errors through rigorous mathematical models like Aristotle.
