Lemony
On premise AI appliance that runs large language models, secure retrieval, and agents entirely on a local device, giving regulated teams generative AI with no cloud and data sovereignty.
Lemony is an on premise artificial intelligence appliance, an AI in a box that lets an organization run generative AI entirely on its own hardware with no cloud dependence. Founded and led by chief executive Sascha Buehrle, the company raised a two million dollar seed round led by True Ventures and shipped its first plug and play node in 2025. Each node is a small, secure device that hosts a full AI stack and sits inside a company's own network, aimed squarely at teams that cannot send sensitive data to the cloud.
The core promise is data sovereignty. With no cloud connectivity, no data sharing, and an optional physical security key, Lemony directly answers the governance problems that keep regulated industries from adopting AI, including shadow AI, business data leaking into model training, and mounting compliance demands. It is already used across legal, finance, government, and healthcare, and is manufactured in the United States and Europe. Each node ships preloaded with around sixteen open source models, including IBM Granite and Meta Llama variants, and the platform selects the right model for a given task.
On top of the hardware, Lemony runs secure local retrieval augmented generation grounded in a company's own documents, along with specialized agents that can validate work, send notifications on events like regulatory changes, and automate recurring tasks. Lemony Adapters add focused expert knowledge for specific domains such as legal, finance, quality assurance, and medical. Teams get custom AI assistants with no code, an auto indexing knowledge base that stays searchable without indexing delays, and prompt templates to streamline everyday work.
Governance is built in, with centralized administration, defined AI access policies, prompt shields, and real time oversight of how data flows and how models decide. Nodes are stackable, so teams can add units to form larger private clusters and connect them under a federated architecture where knowledge is shared only as far as access policies allow. A software development kit connects Lemony to existing tools, and launch partners include IBM, JetBrains, and the public sector reseller Carahsoft.

Use cases & customers
In practice
A law firm can only put ten percent of its documents into a cloud AI tool because of privacy rules. With a Lemony node on its own network, it processes one hundred percent of them, nothing ever leaving the building.
A hospital wants to make its internal knowledge searchable for staff but cannot risk patient data touching the cloud. Lemony runs the models and retrieval locally, so sensitive information never leaves the local network.
A small finance team needs private AI without hiring specialists. They plug in a Lemony node, upload their documents, pick from the preloaded models, and are running secure assistants within minutes.

| Integrations & Tool CallingLemony ships a software development kit to connect existing tools and grounds answers in uploaded or connected business data, real connectivity though short of a documented catalog of prebuilt enterprise connectors, so partial. | Partial |
|---|---|
| Workflow OrchestrationLemony runs specialized agents that validate work, send event notifications, and automate recurring tasks as part of end to end local AI workflows, agent based automation short of documented deep multi step orchestration, so partial. | Partial |
| Knowledge Grounding & RAGLemony runs secure local retrieval augmented generation grounded in a company's own documents with automatic background indexing, strong data grounding though explicit source citation was not documented, so partial. | Partial |
| Human Oversight & GuardrailsLemony provides centralized governance, defined AI access policies, prompt shields, and real time oversight of data flows and model decisions, a real governance layer short of a full runtime enforcement engine, so partial. | Partial |
| Security, Identity & GovernanceLemony runs entirely on premise with no cloud connectivity, an optional physical security key, user and project administration, and defined access policies, real access governance, though named certifications were not verifiable, so partial. | Partial |
| Observability & AuditabilityLemony offers real time oversight into data flows and model decisions across its nodes, meaningful visibility short of a comprehensive per action audit trail, so partial. | Partial |
| Memory & State PersistenceLemony keeps an auto indexing local knowledge base grounded in company documents, but a persistent cross session agent memory could not be verified. | Unable to verify |
| Deployment & Data ResidencyLemony is a hardware based on premise appliance that runs the full artificial intelligence stack locally with no cloud connectivity and stackable nodes for private clusters, genuine self hosted deployment and data residency, so full. | Full |
| Prebuilt Agents, Templates & PacksLemony ships Lemony Adapters with domain expert knowledge for legal, finance, quality assurance, and medical, plus specialized agents and prompt templates, a curated pack short of a browsable marketplace of cloneable agents, so partial. | Partial |
| Triggers & Channel CoverageLemony agents can send notifications on events such as regulatory changes and automate recurring tasks, real event and schedule triggering though on a single local device with narrow channel coverage, so partial. | Partial |
| Model Flexibility & RoutingEach Lemony node comes preloaded with around sixteen open source models, including IBM Granite and Meta Llama variants, and the platform selects the right model for each task, genuine multi model flexibility and routing, so full. | Full |
| APIs, SDKs & MCP ExtensibilityLemony provides a software development kit to connect the appliance to existing tools, though a matching public developer application programming interface and Model Context Protocol server were not both confirmed, so partial. | Partial |
