Core Viewpoint - Harmonic AI, co-founded by Vlad Tenev and Tudor Achim, aims to develop an AI system capable of solving complex mathematical problems, striving for Mathematical Superintelligence (MSI) [3][20]. Group 1: Company Overview - Harmonic AI has successfully raised $100 million in Series B funding, bringing its valuation to approximately $875 million [4][17]. - The company was co-founded by Vlad Tenev, who previously established Robinhood Markets, and Tudor Achim, an expert in AI and large model training [5][15]. - Robinhood, under Tenev's leadership, achieved a market cap of around $22.7 billion and reported a revenue of $927 million with a net profit of $336 million in Q1 2025 [8][12]. Group 2: Funding and Valuation - Harmonic AI's Series A funding raised $75 million, led by Sequoia Capital, with a post-money valuation of $325 million [15]. - The recent Series B funding was led by Kleiner Perkins, with participation from Paradigm and Ribbit Capital, among others [16]. - The company intentionally set its valuation below the "unicorn" threshold of $1 billion, focusing on long-term growth rather than short-term valuation targets [18][19]. Group 3: Product Development - Harmonic AI announced its first model, Aristotle, which can formalize natural language problems into formal representations, enhancing collaboration with mathematicians [20]. - The model's performance improved from 83% to 90% on the MiniF2F benchmark, which includes various levels of mathematical problems [23]. - The ultimate goal is to create an AI system with mathematical capabilities surpassing human abilities, addressing challenges like the "hallucination" problem in AI [26][28].
