What Silence laboratories does

Silence Laboratories is a Singapore-incorporated cryptography company founded in 2019 that builds privacy-preserving computing and collaboration infrastructure for institutional digital asset custody, Web3 wallets, and regulated financial services. Its core technology stack combines Multi-Party Computation (MPC), Post-Quantum Cryptography (PQC) based on the NIST-approved ML-DSA standard (FIPS 204), Threshold Signature Schemes (TSS), and Trusted Execution Environments (TEE), delivered through a portfolio of products including Silent Shard (MPC-TSS key management powering 10M+ accounts), Silent Compute (privacy-preserving computation over distributed data with secure match, statistics, and ML), CCVM (secrets management and distributed authorization), Post-Quantum MPC (quantum-safe enterprise wallet), AP3 (open protocol for privacy-preserving multi-agent collaboration, donated to Linux Foundation Decentralized Trust), and Silent Pay (stablecoin payments infrastructure).

The company's go-to-market combines enterprise field sales to institutional digital asset custodians and banks (BitGo, Eigen Labs, Bron, Zengo, Infosys as design partners), an SDK/API distribution channel embedding MPC into Web3 wallets and platforms (MetaMask, Okto, TanX, MoonGate, Easy Crypto, Chalo, Lighthouse), and event-driven demand generation through the annual DeCompute conference. Revenue is generated through enterprise subscriptions, SDK licensing, on-prem deployment, and node-as-a-service offerings with custom quote-based pricing and multi-year contracts. The company has raised approximately $7.3M across seed rounds in 2022 and 2024 led by Pi Ventures, with a smaller round in 2025, and employs a globally distributed team of 30-50 contributors across 18+ countries anchored by researchers from MIT CSAIL, UIUC, NUS, and SUTD with 10+ tier-1 academic publications.

Revenue model

1. Silent Shard (MPC-TSS licensing/integration): Enterprise license and integration fees for MPC-based key management infrastructure (Silent Shard) sold to digital asset custodians, wallets, and financial institutions. Revenue is derived from SDK integration, on-premise deployment, and node-as-a-service offerings. Professional support, migration, and maintenance services are bundled.
2. Post-Quantum MPC Wallet Infrastructure: First production-ready post-quantum MPC wallet for enterprise digital asset custody. Sold as institutional infrastructure to custodians, banks, and crypto platforms via direct sales and design partnership programs.
3. Silent Pay (Stablecoin Payments): Stablecoin payment infrastructure sold as a single-integration API to banks, neobanks, payment service providers, remittance companies, and payroll platforms. Revenue likely derived from transaction fees, API usage, and possibly subscription for enterprise deployments.
4. Silent Compute / CCVM (Privacy-Preserving Compute): Privacy-preserving computation infrastructure sold to financial institutions, telecom companies, healthcare providers, and enterprises needing cross-institutional data collaboration without exposing raw data. Revenue model includes platform/subscription fees for multi-party compute infrastructure and per-query or per-computation fees for specific PET capabilities.
