What Primus does
Primus is a Hong Kong-headquartered IT company founded in 2023 (originally as PADO Labs, rebranded to Primus in March 2025) that builds cryptographic verification infrastructure for the Web3 and AI ecosystem. Its core technology combines zkTLS (zero-knowledge transport layer security) with zkFHE (zero-knowledge fully homomorphic encryption) to enable tamper-resistant attestation of arbitrary off-chain web data and confidential computation on encrypted data, addressing the trust gap between Web2 data sources and on-chain applications. Product surface includes the Primus Extension browser plugin, MPC-TLS SDK, Primus Developer Hub, Proof-of-Reserves for institutions, the zkDID identity framework, the decentralized AlphaNet attestor network, and Primus Skills for AI agent verifiability.
The company serves three primary use-case segments: DeFi and Web3 protocols requiring verifiable off-chain data and credit signals; AI agents and applications needing cryptographic proof of data source authenticity and agent actions; and privacy-first data networks enabling KYC and identity verification without disclosing raw personal data. Its go-to-market is product-led and developer-focused, distributing open-source code via GitHub, documentation at dev.primuslabs.xyz, and the Chrome Web Store extension, with an integration ecosystem of 40+ partners including BNB Chain, Brevis, Nillion, Phala, Kite AI, Circle, and Pharos Network. Revenue model is usage-based via API/SDK access and technology licensing, although pricing is not publicly disclosed; total disclosed funding is approximately $6.5M across a 2023 seed and a January 2025 round led by Dispersion Capital, Symbolic Capital, and VanEck with participation from Alchemy, Samsung NEXT, and Maelstrom.

Primus competitors and assessment
Company assessmentDirect peers
- Brevis: zk co-processor enabling verifiable off-chain computation. Primus is a current integration partner (joint zk attestation framework), but Brevis overlaps directly in verifiable data and proof markets.
- Reclaim Protocol: Direct zkTLS competitor offering zero-knowledge attestations of Web2 data for on-chain use. Targets the same developer base with overlapping DeFi and identity verification use cases.
- Nillion: Blind computation network for processing encrypted data without decryption. Adjacent to Primus's zkFHE offering and explicitly integrated as a partner for privacy-preserving workflows.
- Phala Network: TEE-based confidential computing platform integrated with Primus's attestor service. Competes in the same verifiable-compute / privacy infrastructure category.
- Sunscreen: FHE and privacy tooling for Web3, co-developing a privacy-first token distribution protocol with Primus. Direct overlap on FHE-based developer tooling.
Emerging players
- Opacity Network: zkTLS-based verifiable data network for Web3; smaller and earlier-stage but competes in the same Web2-to-Web3 attestation niche.
- Lit Protocol: Decentralized key management and conditional signing using MPC/TLS — closely aligned with Primus's MPC-TLS SDK and verifiable computation approach.
Broad incumbents
- Chainlink: Dominant oracle and cross-chain infrastructure platform. Competes broadly for developer attention on data verification, though Primus differentiates on zero-knowledge privacy and off-chain data attestation.
- Aztec Network: Privacy-first zkRollup with confidential smart contract execution. Overlaps with Primus's privacy-preserving DeFi and identity use cases at a larger scale.
- Worldcoin / Tools for Humanity: Privacy-preserving identity verification at scale using zero-knowledge proofs. Comparable in zkDID ambition though Primus is platform-agnostic rather than biometric-based.
