Tinfoil
Tinfoil is a verifiably private AI platform built to deliver zero-trust, zero-data-retention inference by running open-source or custom models inside secure hardware enclaves in the cloud, giving you the data-privacy assurances of on-premises systems with the scalability and convenience of the cloud. All user inputs and inference operations are processed in confidential-computing environments so that no one, not even Tinfoil or the cloud provider, can access or retain your data. It supports private chat, private data analysis, user-trained fine-tuning, and an OpenAI-compatible inference API, covers workloads such as AI agents, private content moderation, and proprietary code models, and provides features like public verification of enclave attestation, “provable zero data access,” and full compatibility with major open source models.

Multifactor
Multifactor is a next-generation account-sharing and access-management platform built around zero-trust, post-quantum cryptography, and fine-grained permissioning. Rather than simply sharing credentials, users store their online accounts (passwords, passkeys, 2FA codes) in a secure vault and grant access to humans or AI agents by sending controlled links. Access can be revoked instantly, and the underlying credentials remain hidden. You can define precise permissions (for example, “read transactions” but not “initiate transfers”), capture detailed non-repudiable audit trails of every action, and enjoy built-in encryption and post-quantum security architecture that ensures only authorized parties ever gain access. The platform can also operate as a full identity-and-access-management suite, supporting authentication (biometrics, hardware tokens), authorization, access auditing, device and network endpoint enforcement, and secure account/resource sharing.

Privatemode AI
Privatemode is an AI service like ChatGPT—but with one critical difference: your data stays private.
Using confidential computing, Privatemode encrypts your data before it leaves your device and keeps it protected even during AI processing. This ensures that your information remains secure at all times.
Key features:
End-to-end encryption: With confidential computing, your data remains encrypted at all times - during transfer, storage, and during processing in main memory.
End-to-end attestation: The Privatemode app and proxy verify the integrity of the Privatemode service based on hardware-issued cryptographic certificates.
Advanced zero-trust architecture: The Privatemode service is architected to prevent any external party from accessing your data, including even Edgeless Systems.
Hosted in the EU: The Privatemode service is hosted in top-tier data centers in the European Union. More locations are coming soon.
