Lambdaclass

Lambda is a deep tech venture studio blending research and engineering, with global offices and expertise from cryptotgraphy, distributed systems and compilers

Lambda

We are a deep tech engineering firm founded in 2014. We build software that is fast and provably correct using Lean 4, Rust, and Erlang/Elixir. With 100+ engineers specializing in formal verification, cryptography, distributed systems, and high-performance software, we operate teams in Buenos Aires, Montevideo, and Barcelona as part of Ergodic Group.

Philosophy

Most software relies on faith rather than proof. We advocate for mathematical guarantees about software behavior. Formal verification is an evolution beyond memory safety: the machine checks the reasoning, the code is public by default, and correctness is a property of the system, not a hope.

Areas of Work

  • Verified Optimization
  • Verifiable Computation (zero-knowledge proofs, verifiable execution)
  • High-Performance Systems
  • Distributed Systems (consensus, P2P networking, fault-tolerant architectures)
  • Safety-Critical Software (aerospace, automotive, finance)
  • Artificial Intelligence
  • Engineering Software
  • Post-Quantum Cryptography

Selected Projects

Blockchain Infrastructure
