July 31, 2025 – TACEO, a leading innovator in privacy-enhancing technologies, today announced it has successfully closed a $5.5 million Seed funding round. The round was led by Archetype, with significant participation from a16z crypto CSX, cyber•Fund, a_capital, polymorphic, daedalus_angels, wagmi_vc, and other strategic investors. This substantial investment will accelerate TACEO's mission to build the foundational network for private shared state and proof delegation, unlocking the full potential of verifiable encrypted computation across various industries.
TACEO is at the forefront of addressing a critical gap in the industry: the need for private computation that maintains verifiability. The company's core innovation lies in its development of coSNARKs (Collaborative SNARKs), a novel approach that combines the strengths of Multiparty Computation (MPC) and Zero-Knowledge Proofs (ZKP). This powerful synergy enables collaborative computation on encrypted data with verifiable correctness, allowing parties to compute on private data from different sources while ensuring confidentiality.
"We are incredibly excited to announce our Seed funding, which is a resounding validation of our vision to bring verifiable encrypted compute to the masses," said Lukas Helminger, CEO of TACEO. "The support from Archetype and our esteemed investors empowers us to rapidly expand our development efforts and solidify TACEO's position as the leading infrastructure for private shared state. We believe that unlocking the ability to privately collaborate and prove publicly is essential for the next generation of decentralized applications and beyond."
The newly secured capital will be deployed to further develop TACEO's suite of products and expand its engineering team. Key components of the TACEO ecosystem include:
- CoCircom: Developer tooling for running Circom circuits in an MPC environment, which is already feature complete.
- CoNoir: Collaborative SNARKs for Noir circuits, currently in active development.
- TACEO:Proof: A coSNARK network for private proof delegation, which is already live in production and ready for use. This allows users to outsource proof generation without compromising witness privacy.
TACEO's technology is poised to revolutionize multiple sectors by enabling previously inaccessible data to fuel new industry pillars:
- DeFi: CoSNARKs and Private Shared State enable confidential, verifiable trading in decentralized finance. This facilitates use cases like dark pools, allowing participants to match orders without exposing prices or strategies, while ensuring all trades settle correctly on-chain, leading to new designs for fair, trustless financial markets.
- AI: In collaborative AI, Private Shared State allows multiple data owners to train models on combined datasets without revealing sensitive information. CoSNARKs prove the correctness of these computations, ensuring both privacy and verifiability in multiparty machine learning.
- Data Ownership: TACEO gives users real control over their data by enabling computations across encrypted datasets. With coSNARKs, users can delegate private proof generation without leaking inputs, maintaining data sovereignty while enabling trustless services like credit scoring or attestations.
- Gaming: Private Shared State allows players to make hidden moves in on-chain games, such as secret bids or unseen strategies, while coSNARKs ensure that outcomes are fair and provable, resulting in fully decentralized games that are both private and cheat-proof.
With an experienced team of cryptographers, engineers, and entrepreneurs, including co-founders Christian Rechberger (Chief Scientist) and Roman Walch (Lead Cryptographer), TACEO is committed to making private computation the default option in Web3 and beyond. The company recently announced that TACEO:Proof went live in production on July 23, 2025, marking a significant milestone in its journey.
