Harmonic Debuts AI Math Chatbot with Verified Accuracy

Artificial intelligence startup Harmonic, co-founded by Robinhood CEO Vlad Tenev, has launched its AI-powered math chatbot Aristotle on iOS and Android platforms. The application, currently in beta testing, promises to deliver "hallucination-free" mathematical reasoning—a bold claim in an industry where AI reliability remains a persistent challenge.

The Promise of Mathematical Superintelligence

Harmonic positions Aristotle as the foundation for achieving Mathematical Superintelligence (MSI), with applications spanning physics, statistics, and computer science. "Aristotle is the first product that can reason and formally verify its output," said Tudor Achim, Harmonic's CEO and co-founder, in an interview with TechCrunch. "In supported quantitative reasoning areas, we guarantee no hallucinations."

The company plans future expansions including:

• An API for enterprise integration
• A web-based consumer application
• Broader domain coverage beyond core mathematics

Benchmark Performance and Funding Momentum

Harmonic reports that Aristotle achieved gold medal performance in the 2025 International Mathematical Olympiad (IMO) through formal verification testing—where problems were converted to machine-readable formats for validation. This contrasts with informal natural language tests used by Google and OpenAI's models, which also earned IMO gold medals.

The launch coincides with Harmonic's recent $100 million Series B funding round led by Kleiner Perkins, valuing the company at $875 million. Achim attributes investor confidence to rapid progress toward MSI development.

Technical Differentiation Through Verification

Unlike conventional AI models, Aristotle employs the open-source programming language Lean to algorithmically verify solutions before delivering answers. This dual-check system:

1. Generates solutions using AI
2. Validates correctness through non-AI algorithmic processes

The approach mirrors verification methods used in high-stakes fields like medical devices and aviation systems.

Industry Context and Future Outlook

The launch comes as major tech firms intensify efforts to develop mathematical reasoning capabilities in AI systems. Mathematics represents a unique domain for AI development because:

• Solutions are objectively verifiable
• Core reasoning capabilities may transfer to other disciplines
• Precision requirements eliminate tolerance for hallucinations

While creating hallucination-free AI remains extraordinarily difficult in narrow domains, Harmonic's verification framework represents significant technical advancement. ---

Key Points:

• Precision Focus: Aristotle specializes in mathematically verifiable solutions with guaranteed accuracy
• Funding Momentum: $100M Series B at $875M valuation signals strong market confidence
• Technical Edge: Unique Lean-powered verification system prevents AI hallucinations
• Competitive Benchmark: Formally verified IMO gold medal performance distinguishes from rivals
• Expansion Plans: API and web versions will broaden access beyond mobile platforms
