Harmonic AI raised $100M Series B, valuing it at $875M
Harmonic AI, co-founded by Robinhood CEO Vlad Tenev, has raised $100 million in a Series B round led by Kleiner Perkins. The funding values the Palo Alto-based AI company at approximately $875 million. The funds will be used to expand research teams and accelerate product development.
Harmonic announced a $75 million Series A funding round at a $325 million post-money valuation, led by Sequoia Capital with participation from Index Ventures and others. The funding will accelerate the development of Mathematical Superintelligence (MSI), an AI with superior mathematical capabilities. Harmonic's model, Aristotle, achieves 90% on the MiniF2F benchmark. Co-founders Vlad Tenev and Tudor Achim emphasize MSI's potential to overcome AI limitations and advance various fields.
Harmonic, an early stage startup working on software to mitigate against unregulated AI apps harvesting company data at scale, has attracted $17.5 million in new funding as venture capital investors double down on AI security companies.
