TACEO

Based in Austria, TACEO specializes in providing a compute network that enables secure collaborative computation on encrypted data, addressing privacy needs in various sectors such as finance, AI, and gaming. TACEO, founded in 2022 and headquartered in Graz, Austria, offers solutions for private shared state and proof delegation. The company raised USD 5. 5 mn in Seed funding on July 31, 2025, led by Archetype, with participation from Andreessen Horowitz, Cyber Fund, A Capital Partners, and Polymorphic Capital.

The firm has engaged in one deal to date. TACEO's core offering revolves around a compute network designed for private shared state and proof delegation, enabling collaborative computation on encrypted data. Central to their technology are CoSNARKs and Private Shared State (PSS), which leverage the strengths of Multiparty Computation (MPC) and Zero-Knowledge Proofs (ZKPs) to provide controlled access to sensitive data while maintaining confidentiality and verifiability. Key use cases include facilitating confidential trading in decentralized finance (DeFi), enabling secure collaborative AI model training without exposing private data, and ensuring fair outcomes in blockchain gaming.

The platform is designed for a diverse client base that spans industries such as finance, artificial intelligence, and gaming, serving customers who require privacy-centric solutions across various geographical markets, including North America and Europe. TACEO generates revenue through a structured business model focused on partnerships and B2B transactions. Their flagship product, TACEO:Proof, allows clients to outsource proof generation without compromising the privacy of sensitive data, positioning it as an essential tool for enterprises needing secure verification processes. The company engages in subscription-based pricing for its services, providing clients with access to its network and tools based on varying tiers of usage or features.

As clients leverage TACEO's technology for applications such as credit scoring, verifiable trading, and private computation, the revenue model is expected to facilitate a steady flow of transactions, driven by the growing demand for privacy-preserving technologies in numerous sectors. In July 2025, TACEO raised USD 5. 5 mn in Seed funding, which will be used to support the further development of its infrastructure performance. The company is planning to enhance its product offerings and introduce new solutions that cater to the privacy needs of its clients.

Additionally, TACEO aims to expand into markets in North America and Europe, focusing on sectors requiring high confidentiality standards. The recent funding will enable these initiatives to be executed effectively, enhancing their market presence.
