Let us know! As our team grows and our needs evolve we will proactively keep you in mind as opportunities arise that may be well suited for you. We're grateful for your interest in joining us on the path to mathematical superintelligence and look forward to staying in touch. Best, Tudor and Vlad ## About Harmonic ## Company Overview - **One-liner**: Harmonic is an AI research lab building the world’s most advanced mathematical reasoning engine to achieve verifiable, safe, and superhuman mathematical intelligence. - **Entity Type**: Private (Series C, $1.45B valuation) - **Headquarters**: Palo Alto, California, United States - **Founded**: 2023 - **Founders**: Tudor Achim (CEO) and Vlad Tenev (Executive Chairman) ## Core Business - **Primary industry**: Artificial intelligence / AI research, with a focus on formal mathematical reasoning and automated theorem proving. - **Target customers**: B2B, enterprise – safety-critical industries such as aerospace, chip design, industrial systems, and healthcare where software reliability is paramount. - **Mission**: “To explore the frontiers of human understanding” and build mathematical superintelligence (MSI) – AI with mathematical capabilities superior to humans. ## Products & Services - **Aristotle**: An automated theorem prover that achieved gold‑medal level performance on the 2025 International Mathematical Olympiad. It advances the state‑of‑the‑art on the MiniF2F benchmark (83% success rate with external computer algebra systems, 63% when restricted to Lean). [harmonic.fun/news/intro-harmonic](https://harmonic.fun/news/intro-harmonic/) - **Yuclid**: An open‑sourced theorem prover that provides visibility into proof traces (announced alongside Aristotle’s IMO results). [harmonic.fun/news/intro-harmonic](https://harmonic.fun/news/intro-harmonic/) ## Market Standing - **Valuation/Market Cap**: $1.45 billion (Series C, November 2025) [linkedin.com/company/harmonicmath](https://www.linkedin.com/company/harmonicmath) - **Key Metric**: Total funding of $295M (Series A $75M, Series B $100M, Series C $120M). Revenue is not publicly available. - **Notable Investors/Partners**: Sequoia Capital (lead Series A), Kleiner Perkins (lead Series B), Ribbit Capital (lead Series C), Index Ventures. [harmonic.fun/news/intro-harmonic](https://harmonic.fun/news/intro-harmonic/) - **Growth Signals**: 41.9% year‑over‑year headcount growth (37 employees); three funding rounds in 14 months; first research model (Aristotle) achieving state‑of‑the‑art results. [linkedin.com/company/harmonicmath](https://www.linkedin.com/company/harmonicmath) ## Competitive Advantages - **Formal mathematical reasoning**: Models produce outputs that are guaranteed correct through verifiable, interpretable proof traces – fundamentally safer than current LLM‑based systems. - **Full‑stack RL ownership**: The team owns the entire reinforcement learning stack – from low‑level environment simulators and custom communication primitives to distributed training loops and inference engines. [harmonic.fun/careers](https://harmonic.fun/careers/) - **Founding team depth**: Co‑founders with deep AI and scale‑up experience (Tudor Achim co‑founded Helm.ai; Vlad Tenev co‑founded Robinhood), attracting top talent from Anthropic, Meta, and top research universities. [linkedin.com/company/harmonicmath](https://www.linkedin.com/company/harmonicmath) - **Open ecosystem**: Open‑sourcing tools like Yuclid to build community and accelerate adoption of formal methods. ## Strategic Focus - **Scale Mathematical Superintelligence (MSI)**: Continue advancing Aristotle’s capabilities and integrate MSI into real‑world safety‑critical applications. - **Expand research and engineering team**: 8 active job postings across research, infrastructure, product, and machine learning systems. [harmonic.fun/careers](https://harmonic.fun/careers/) - **Bridge research and production**: Build robust, scalable infrastructure to turn research ideas into deployable systems. [harmonic.fun/careers](https://harmonic.fun/careers/) ## Why Work Here - **Mission‑driven work**: Contribute to AI safety and fundamental science – building AI that can be trusted because its reasoning is provably correct. - **Cutting‑edge technical challenges**: Work on low‑level RL systems, formal theorem proving, and distributed training at scale. The team operates like a commercial research lab with high ownership. [harmonic.fun/careers](https://harmonic.fun/careers/) - **Strong talent density**: Team includes researchers and engineers from Meta, Anthropic, Perimeter Institute, UC Berkeley, Stanford – a fast‑growing, high‑caliber group. [linkedin.com/company/harmonicmath](https://www.linkedin.com/company/harmonicmath) - **Location & flexibility**: Based in Palo Alto, CA (headquarters) with a second office in the UK. Job postings list “Palo Alto” as location – likely primarily in‑office. [harmonic.fun/careers](https://harmonic.fun/careers/) - **Growth trajectory**: Rapidly scaling startup ($295M raised, 41.9% headcount growth) offering early‑employee impact and career growth. ## Sources 1.
