Harmonic, an AI lab developing Mathematical Superintelligence (MSI), has announced a $100 million Series B funding round, valuing the company at nearly $900 million post-money. Kleiner Perkins led the round with significant participation from Paradigm. Additional investors include Ribbit Capital and existing backers such as Sequoia Capital, Index Ventures, and Charlie Cheever.
This funding will accelerate Harmonic’s advancements in mathematical reasoning and the commercialization of its flagship model, Aristotle. Unlike language-based AI, Aristotle uses MSI to verify accuracy, ensure logical coherence, and transparently flag errors. This allows it to deliver provable solutions for high-stakes, real-world applications instead of probabilistic guesses.
Aristotle’s MSI model is designed to solve mathematical problems far exceeding human capabilities, potentially driving breakthroughs in fields like theoretical physics and engineering.
Harmonic previously raised $75 million in its September 2024 Series A round, led by Sequoia Capital with participation from Index Ventures, DST Global partners, and Nikesh Arora.
KEY QUOTES:
“Aristotle’s MSI is uniquely suited for mission-critical applications where there is no margin for error, such as generating verified software and by formally verifying existing code – a breakthrough for industries including blockchain, financial services, aerospace and other safety-sensitive systems.”
Tudor Achim, CEO of Harmonic
“We’re getting closer to AI that can truly reason – quickly, reliably, and at scale. Mathematical Superintelligence is moving from research to real-world applications, and we’re excited for Aristotle to start putting this AI capability into the hands of users.”
Vlad Tenev, Co-Founder and Executive Chairman of Harmonic
“Harmonic has created a new foundation for verified, scalable reasoning that can be trusted in high-stakes environments. I’m deeply excited about the applications of Aristotle not just for software, but for accelerating progress across science, engineering and general intelligence.”
