Leanear

What Leanear does

Leanear SAS is a Paris-based deep-tech company founded in 2018 that provides a Secure AI Deployment Platform for enterprises and AI vendors operating in regulated environments. The platform acts as a cryptographic security layer enabling any AI solution to deploy on-premise, in private cloud, or across multi-cloud environments (AWS, Azure, GCP, OVH, Scaleway) while keeping data and AI model IP under the customer's governance boundary. Core technology is built on advanced cryptography developed in Rust over six years of R&D, with access control embedded directly into the encryption layer — a distinct approach versus conventional bolt-on encryption. The platform comprises two deployment modes (Full Instance Mode for entirely in-customer-environment deployments, and Hybrid Mode with vendor-side processing) and modular components including Secure Transfer, Secure Storage, Secure Communications, Secure Compute, AI Gateway, and Protected Runtime.

The business model combines multi-year enterprise subscriptions, partner revenue share, and licensing fees, with pricing structured around three engagement tiers: Single Use Case (2–4 week deployment), Platform Deployment (4–6 weeks), and Design Partnership (collaborative). Go-to-market is enterprise direct sales paired with a partner ecosystem targeting AI startups that need enterprise-grade deployment to close deals. Target customers are large organizations in defense, aerospace, financial services, healthcare, and critical infrastructure, alongside AI startups requiring on-premise or private-cloud deployment options. The company is backed by Sequoia alongside European VCs (Cygni Capital, Fair Equity, Fondation PSL, Kima Ventures, SNAW VC), with strategic validation from Thales, DGA, and ANSSI. Compliance posture includes GDPR, ISO 27001 readiness, SOC 2 alignment, and EU AI Regulation alignment.

The company's core differentiator is cryptography — not AI model development — applied to the problem of enterprise AI deployment. The platform's value proposition centers on enabling enterprises to adopt AI without compromising data sovereignty, allowing a one-time security validation that then permits deployment of multiple partner AI solutions without additional reviews. Revenue scale is undisclosed; the company lists no enterprise customer names or case studies publicly.

Revenue model

1. Platform/Subscription Revenue: Enterprise customers pay for platform deployment and security validation. Leanear provides the secure infrastructure layer that enables any AI solution to deploy according to enterprise requirements. Revenue model includes platform fees for deployment in customer environment.
2. Partner Revenue Share: Leanear participates in deals they enable, aligning incentives with AI startup and partner ecosystem. Partners win enterprise deals without building enterprise infrastructure.
3. Licensing Fees: Flexible pricing for startups, with costs typically covered by end customers. Hybrid model mixing revenue share and licensing depending on deal type (PoC vs production, customer size) and requirements.

Core offering

Leanear provides a secure AI deployment platform that enables enterprises to deploy any AI solution in their own environment (on-premise, private cloud, or multi-cloud) while maintaining data sovereignty and protecting proprietary model IP. The platform is built on advanced cryptography developed in Rust with access control embedded directly into the encryption layer, and supports multi-cloud flexibility across AWS, Azure, GCP, OVH, Scaleway, and on-premise deployments.

Product overview

Leanear is a Secure AI Deployment Platform providing a unified security infrastructure layer that enables any AI solution to deploy according to enterprise requirements. The platform operates as a platform-plus-modules architecture consisting of two deployment modes (Full Instance Mode and Hybrid Mode) and four core security modules (Secure Transfer, Secure Storage, AI Gateway, Protected Runtime) built on Advanced Encryption technology. Additional components include Secure Communications and Secure Compute. The platform supports deployment across on-premise, private cloud, and multi-cloud environments (AWS, Azure, GCP, OVH, Scaleway) with options for customer cloud subscriptions, dedicated instances, or self-hosted deployment. Security Engineering Services provides custom integration for complex enterprise use cases requiring tailored cryptographic solutions.

Direct peers

• Enveil: Enveil provides privacy-preserving technologies for secure AI and analytics on encrypted data, with zero-trust computation across organizational boundaries. Directly comparable to Leanear's encryption-with-access-control thesis.
• Anjuna Security: Anjuna provides confidential computing platforms that create hardware-isolated enclaves for running AI workloads and protecting data and models. It competes directly with Leanear's Protected Runtime and Secure Compute capabilities.
• Duality Technologies: Duality Technologies provides privacy-enhanced computation and secure AI/ML on encrypted data, focused on regulated industries. Directly comparable technology approach and target verticals to Leanear.
• Skyflow: Skyflow provides a data privacy vault and secure infrastructure for AI/LLM workloads, including encryption-based access control and isolated inference. It is a direct competitor in the secure AI deployment space targeting enterprises with similar cryptographic isolation use cases.
• Fortanix: Fortanix offers a confidential computing and data security platform with runtime encryption, key management, and AI workload protection. It is a direct peer in confidential AI deployment with overlapping cryptography-first positioning.

Others

• Thales (CipherTrust): Thales, an existing Leanear strategic partner, also sells CipherTrust data security and key management products that overlap with some platform capabilities. They are both a partner and adjacent ecosystem player in enterprise cryptography.
• OWASP / AI Security Tools: OWASP and adjacent AI security tool vendors (e.g., Protect AI, Robust Intelligence) address AI threat detection and model security but operate in adjacent markets rather than the secure deployment platform Leanear occupies.

Broad incumbents

• Microsoft Azure Confidential Computing: Azure Confidential Computing offers hardware-isolated enclaves and customer-managed keys for AI workloads. While a broader platform than Leanear, it represents a major incumbent alternative for enterprises already standardized on Azure.
• IBM Hyper Protect Services: IBM Hyper Protect and IBM Cloud for Financial Services provide secure, confidential computing environments with cryptographic isolation for AI. A broad incumbent competitor serving similar regulated-enterprise use cases.

Emerging players

• TripleBlind: TripleBlind offers privacy-preserving AI operations and federated computation, enabling secure AI on sensitive data. Adjacent cryptographic approach to Leanear but with different delivery model (API-based vs. platform).
