What Kakarot Labs does
Kakarot Labs is a Paris-based, venture-backed developer infrastructure company founded in 2022 that builds "Kakarot," a zero-knowledge (ZK) proving engine purpose-built for the Ethereum Virtual Machine (EVM). The technology is implemented in Cairo and enables computational integrity proofs for EVM-based applications without revealing underlying data, positioning the company in the verifiable computation and ZK-rollup subsegment of crypto infrastructure. The company operates an open-source, community-led model, distributing code via GitHub, engaging developers through Discord and a dedicated documentation portal, and publishing technical content on a company blog. Its target customer segment is EVM developers and builders who need efficient ZK proving integrated with Ethereum-compatible tooling; no commercial pricing, enterprise sales motion, or paying customers are publicly disclosed. In 2024, Kakarot announced that it is joining Zama — a company specializing in fully homomorphic encryption (FHE) for the EVM — making Zama its parent company and integrating ZK proving with FHE into a combined privacy and verification platform. Prior to the transaction, the company had closed one funding round on 2023-11-14 led by LongHash Ventures and Stake Capital Group, with a broad syndicate of crypto-native investors.

Kakarot Labs competitors and assessment
Company assessmentEmerging players
- O(1) Labs (Mina Protocol): O(1) Labs develops the Mina Protocol, a ZK-based succinct blockchain with a proving system targeting EVM and Web3 use cases. It is an emerging player with overlapping technology foundations in zero-knowledge proving.
Direct peers
- RISC Zero: RISC Zero builds a ZK proving system (zkVM) for general-purpose computation including EVM-compatible workloads. It is a direct peer to Kakarot as both provide ZK proving engines for verifiable off-chain computation targeting EVM and Ethereum ecosystems.
- Matter Labs (zkSync): Matter Labs develops zkSync, a ZK rollup with EVM compatibility and custom ZK proving circuits. It is a direct competitor in the zkEVM proving space with one of the largest teams and funding rounds in the category.
- Aleo: Aleo is a ZK platform for private application execution with an EVM-compatible direction. It is comparable to Kakarot as both build ZK proving infrastructure aimed at enabling verifiable and privacy-preserving on-chain applications.
- Zama: Zama is the strategic acquirer of Kakarot, specializing in fully homomorphic encryption (FHE) for the EVM. It is a direct peer in the privacy-enhancing computation space for Ethereum and now the parent entity incorporating Kakarot's ZK proving technology.
- Aztec Network: Aztec is a privacy-focused ZK rollup on Ethereum that uses zero-knowledge proofs for private EVM execution. It is comparable to Kakarot due to its focus on ZK proofs combined with EVM compatibility and a privacy-centric angle.
- Polygon zkEVM (Polygon Labs): Polygon zkEVM is a ZK rollup that provides EVM-compatible execution with ZK proof generation. It is a direct peer because it solves the same core problem of generating ZK proofs for EVM execution at scale, with substantially more funding and ecosystem adoption.
- Scroll: Scroll is a zkEVM Layer 2 that produces ZK proofs of EVM execution. It directly overlaps with Kakarot's core technology focus on ZK proving for the Ethereum Virtual Machine.
Broad incumbents
- Linea (Consensys): Linea is Consensys' zkEVM Layer 2 network producing ZK proofs for EVM execution. It is a broad incumbent with the backing of a major Ethereum infrastructure player and overlaps with Kakarot's core ZK-for-EVM proposition.
- StarkWare: StarkWare builds StarkNet and the STARK proving system used for verifiable computation including EVM-like execution. It is a broader incumbent in the ZK proving space with established production deployments and significant ecosystem share.
