Lemony

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.
