TACEO Unveils Private Execution Network for Enhanced Security

A new private execution network is now operational, offering organizations a way to collaborate on shared digital infrastructure without ever exposing their sensitive data. This technology is already at work within a major global identity verification system, processing biometric checks for millions. The core challenge it solves is a modern dilemma: how to participate in common systems for payments, identity, or AI workflows without revealing the confidential parts of those processes to partners or a central platform.

The typical solution forces companies to keep sensitive operations entirely in-house, running critical checks like fraud scoring on isolated systems. This approach concentrates risk, complicates compliance, and prevents organizations from realizing the full potential of shared networks. The TACEO Network introduces a private execution layer designed to sit beneath this shared infrastructure, enabling collaborative computation on encrypted data. Its technology merges two powerful cryptographic methods.

First, Multiparty Computation (MPC) allows multiple independent nodes to compute a function using encrypted inputs, with no single node ever seeing the raw data. Second, Zero-Knowledge Proofs enable a party to verify that a computation was performed correctly without disclosing any underlying information. TACEO fuses these into a system it calls coSNARKs. This allows distributed nodes to not only process encrypted data together but also to generate a verifiable proof of correct execution. The outcome is processing that remains both entirely private and fully auditable.

Founded in 2022 by cryptography researchers from Graz University of Technology, the company is built on strong academic foundations. CEO Lukas Helminger was a researcher and lecturer there, with contributions to national defense projects. Co-founder and Chief Scientist Christian Rechberger is a professor at TU Graz and a co-designer of the Poseidon hash function, a standard in zero-knowledge cryptography. The startup secured a $5.5 million seed funding round in July 2025, led by Archetype VC with participation from a16z CSX, Andreessen Horowitz’s crypto accelerator program.

The network itself is operated by a distributed set of node operators, including the Ethereum infrastructure firm Nethermind and the Faculty of Electrical Engineering at Czech Technical University in Prague. Nodes are distributed across the US, Europe, and Asia. This architecture is fundamental to the security model; because no single entity controls the entire computation, not even TACEO can access the original data. “For decades, the choice was between keeping data private inside one organization or making it visible in shared systems,” Helminger stated. “With our network, that trade-off begins to vanish. Computation can run across independent operators while the data itself stays encrypted.”

The technology is already live within World ID, Sam Altman’s global identity project, where it handles biometric verification. TACEO reports it now secures processes for over 18 million users across 160 countries, an increase from 14 million cited during its summer funding round. This growth aligns with World ID’s public expansion, though the specific figures come from the company’s announcements.

Looking ahead, TACEO’s vision reaches far beyond identity verification. As stablecoins and autonomous AI agents create more complex, automated transactions, the demand for shared digital rails that can process sensitive logic without centralization is accelerating. The company positions its private execution layer as the essential missing component, enabling financial institutions, identity providers, and AI systems to coordinate on common networks without ceding control of their confidential data. The central question now is whether this value proposition will drive widespread enterprise adoption, a challenge the newly launched network must now address.
