What SINE does
SINE Foundation is a Berlin-based non-profit think-and-do tank (registered as SINE e.V.) founded in July 2020 that develops open-source cryptographic software and governance frameworks to solve data sharing dilemmas. The organization's core technology is Secure Multi-Party Computation (MPC), a cryptographic protocol that enables multiple organizations to jointly compute on data without revealing their private inputs, even if all but one participant collude. SINE's primary products are Polytune, an open-source Rust-based MPC engine, and Garble, a domain-specific language and compiler that allows developers to write MPC programs in a Rust-inspired syntax that compiles into efficient binary circuits. Earlier products include Tandem, the first SMPC engine deployable through a web browser (demonstrated via Encryptle, a privacy-preserving Wordle variant). Beyond core tooling, SINE co-authors interoperability protocols — PACT (Product Carbon Transparency, with WBCSD, implemented by 35+ software solutions) and iLEAP (logistics emissions data exchange, with Smart Freight Centre, implemented by 15+ companies).
SINE operates a non-profit business model, funding operations through research grants (e.g., BMFTR-funded ATLAS project), project partnerships, and consulting engagements. All software is published under permissive open-source licenses and distributed free of charge via GitHub. The go-to-market is primarily partnership-driven: SINE collaborates with large coalitions (WBCSD, 200+ members), government agencies (Frankfurt Health Department, Metropolregion Rhein-Neckar), ClimateTech companies (Cozero), and academic institutions (HPI, TU Dresden). Customer segments span sustainability-focused organizations needing to share emissions data, public-sector entities requiring privacy-preserving analytics, and industry coalitions building interoperable data networks. SINE does not disclose revenue, and the organization is governed by a board (Vorstand) of four members with a small core team supplemented by academic and consulting partners.

Its primary products are Polytune, an open-source Secure Multi-Party Computation (MPC) engine written in Rust, and Garble, a Rust-inspired domain-specific programming language and compiler that translates programs into MPC circuits. SINE also co-authors data-exchange protocols (PACT for product carbon footprints, iLEAP for logistics emissions) and publishes frameworks such as the Data Commons methodology.
Product overview
The SINE Foundation is a non-profit think-and-do tank that develops open-source cryptographic software and governance mechanisms for solving data sharing dilemmas. Its core offering combines privacy-enhancing technology (Secure Multi-Party Computation) with governance frameworks to enable organizations to share data securely while maintaining data sovereignty. The main products are Polytune (open-source Rust-based MPC engine) and Garble (a Rust-inspired domain-specific language and compiler for MPC programs), which together allow developers to build privacy-preserving applications. Additional offerings include Tandem (earlier MPC engine), the Simple Benchmarking Primitive (beta tool for secure benchmarking), the Secure Benchmarking Demo, and Encryptle (a demonstration game). SINE also provides methodology through the Data Commons Framework and protocols including PACT (product carbon footprint exchange) and iLEAP (logistics emissions data exchange), developed in collaboration with organizations like WBCSD and Smart Freight Centre. Educational resources include whitepapers and an article library.

SINE competitors and assessment
Company assessmentBroad incumbents
- IBM: IBM participates in WBCSD's Pathfinder Network alongside SINE and offers broader privacy-enhancing technologies including FHE and confidential computing via its research and cloud portfolio. It is the broad incumbent whose enterprise reach SINE must leverage via partnerships.
Direct peers
- Duality Technologies: Duality offers a secure data collaboration platform combining homomorphic encryption and MPC for regulated industries. Like SINE, it targets cross-organizational analytics on sensitive data without exposing plaintext inputs.
- Inpher: Inpher provides an enterprise Secure Multi-Party Computation platform (XOR Platform) for privacy-preserving analytics and ML across organizations. It is the most direct commercial analogue to SINE's Polytune, serving similar regulated-industry and cross-party data collaboration use cases.
- Enveil: Enveil uses FHE to enable secure search and analytics over encrypted data, serving financial services and government customers. It addresses the same secure cross-organizational data collaboration problem SINE solves, via a complementary cryptographic approach.
- TripleBlind: TripleBlind delivers privacy-preserving computation APIs for healthcare and financial services, supporting federated learning and MPC. It competes in the same category of regulated-industry secure data collaboration that SINE targets.
- Opaque Systems: Opaque provides a confidential computing platform combining secure enclaves with MPC for collaborative AI and analytics on sensitive data. It targets enterprises that need the kind of cross-party privacy guarantees SINE offers, with a more enterprise SaaS delivery model.
Emerging players
- Partisia Blockchain: Partisia offers an MPC-based blockchain and privacy-preserving computation platform for decentralized data collaboration and tokenization. It is an emerging player intersecting Web3 and MPC where SINE could increasingly compete as it expands beyond sustainability use cases.
- Zama: Zama builds open-source fully homomorphic encryption (FHE) tooling (Concrete, fhEVM) for AI and blockchain workloads. It is an emerging alternative privacy-enhancing technology stack that overlaps with SINE's MPC positioning for confidential computation.
Regional players
- Polyteia: Polyteia is a German data and analytics platform for municipalities and is SINE's integration partner in the ATLAS project for privacy-preserving municipal data analysis. It is the closest regional peer addressing the same DACH public-sector MPC use cases.
Others
- Cryspen: Cryspen provides commercial cryptographic services and verified implementations using the hax toolchain, and is SINE's verification partner. It sits in the MPC ecosystem as an enabling technology supplier rather than a direct competitor.
