What Math does

Math, Inc. is a Palo Alto-based AI company founded in 2023 that builds autoformalization technology, software that translates natural language mathematical proofs into machine-verifiable Lean 4 code. Its flagship product, Gauss, is described as a first-of-its-kind autonomous agent that operates continuously for hours and has produced verified formalizations at unprecedented scale, including the Fields Medal-winning sphere packing proof in dimensions 8 and 24 (~200,000 lines of Lean code in three weeks) and the Strong Prime Number Theorem (~25,000 lines in three weeks). Supporting products include OpenGauss, an open-source autoformalization harness for Lean 4 available on GitHub; FormalQualBench, a benchmark of 23 graduate-level theorems with specification-based evaluation via the Comparator tool; and Trinity Environments infrastructure built with Morph Labs to scale Lean verification to thousands of concurrent agents consuming multiple terabytes of cluster RAM.

The company serves three customer personas: research mathematicians (primary), proof engineers, and AI research organizations. Distribution relies on a community-led, product-led model: open-source GitHub repositories, a selective email-based early access program for Gauss, and the Veritas Fellowships research program partnering with Fields Medalists Terence Tao and Maryna Viazovska along with Kevin Buzzard on landmark formalizations including Fermat's Last Theorem and universal optimality of the Leech lattice. Pricing is not publicly disclosed; the only confirmed capital inflows are DARPA expMath program support, a $0 Torch Capital line item in 2025, and a $15 million seed round in March 2026 led by Chapter One and Robot Ventures. The company operates with 1–10 employees and has no disclosed revenue.

Core offering

Math, Inc. builds Gauss, a frontier AI autoformalization agent that autonomously translates natural language mathematical proofs into verified Lean 4 code. The company also offers OpenGauss, an open-source autoformalization harness for Lean, the FormalQualBench benchmark for evaluating autoformalization agents, and the Trinity verification infrastructure developed with Morph Labs to scale Lean environments to thousands of concurrent agents.

Product overview

Math, Inc. offers a unified product portfolio centered on Gauss, a frontier autoformalization agent for mathematical proof verification. Gauss operates autonomously to translate natural language mathematics into verified Lean 4 code. Supporting this core agent are OpenGauss (an open-source harness version for practitioners), FormalQualBench (a benchmark and evaluation framework for the formal mathematics community), and the Veritas Fellowships research program partnering with Fields Medalists. The Trinity environments infrastructure, built with Morph Labs, provides the scalable cloud infrastructure enabling thousands of concurrent verification agents. The portfolio enables formalization at unprecedented scale—from 3,500 lines in June 2025 to 200,000 lines in February 2026—while maintaining the same wall-clock time.

Partnerships

Two partnerships are on record, tiered core.

• Morph LabscoreTechnology or IntegrationPartnership with Morph Labs for Trinity environments infrastructure, developed in collaboration with Morph Labs' cloud platform. This infrastructure scales Lean verification environments to thousands of concurrent agents, each with its own Lean runtime, consuming multiple terabytes of cluster RAM. Infinibranch on Morph Cloud was critical for enabling Gauss to operate at scale.
• Lean Community / Mathlib MaintainerscoreTechnology or IntegrationCollaboration with the Lean mathematical library community, including Mathlib maintainers and the Institute for Computer-Aided Reasoning in Mathematics. This includes collaboration on sphere packing formalization with maintainers Chris Birkbeck, Sidharth Hariharan, Seewoo Lee, Bhavik Mehta, and others, as well as support from Kevin Buzzard, Jeremy Avigad, David Loeffler, Gareth Ma, Pietro Monticone.

Direct peers

• Harmonic: Harmonic builds Aristotle, an AI agent for formal mathematical reasoning in Lean, the closest direct competitor to Math's Gauss/OpenGauss. Aristotle is benchmarked head-to-head on FormalQualBench.

Broad incumbents

• Google DeepMind: DeepMind pursues formal mathematics through AlphaProof and the Formal Conjectures benchmark, applying frontier AI to Lean-level reasoning. While a much larger organization, it overlaps directly on AI-for-formal-math.
• xAI: Mentioned in restructuring context (founding-team departures including Tony Wu and Jimmy Ba); a frontier AI lab that could pursue formal math as an extension of its reasoning research, indirectly competing with Math's long-term vision.
• Anthropic: Anthropic's Claude Code, including MCP and Skills variants, is benchmarked on FormalQualBench as a baseline harness. As Claude improves, Anthropic could ship native formal-math capabilities that compress Math's lead.
• OpenAI: OpenAI develops Codex, which appears in FormalQualBench results and represents a frontier LLM alternative to specialized autoformalization agents. Any first-party formal-math tooling from OpenAI would directly compete with Gauss.

Emerging players

• Cambridge / Imperial Lean Research Groups: Academic Lean research groups (including Kevin Buzzard's group at Imperial) have historically driven Mathlib and now collaborate with Math through Veritas Fellowships. They are simultaneously collaborators and potential sources of competing formalization tooling.

Others

• Lean Community / Mathlib Maintainers: The open-source Lean prover and Mathlib library are the foundation that Math's products are built on and Math actively contributes to. While not a commercial competitor, this community sets platform direction and governance.
• Institute for Computer-Aided Reasoning in Mathematics: Academic institute collaborating with Math on Mathlib and sphere packing formalization; represents the broader academic formal-math ecosystem that Math both draws from and contributes to.
• DARPA (expMath program): The Defense Advanced Research Projects Agency funds Math through the expMath program, validating the technology and providing a potential channel into defense formal-verification applications.
• Morph Labs: Morph Labs provides the Morph Cloud infrastructure that powers Trinity Environments, Math's scalable Lean verification infrastructure. A deep technology partner with potential to expand into adjacent formal-verification workloads.
