Zylon is a Madrid-based enterprise AI company built by the creators of PrivateGPT, the open-source private-LLM project with 55–57k GitHub stars. It sells a fully on-premise private AI platform — AI Core (local LLMs, vector DB, GPU orchestration), an OpenAI-compatible API gateway, and a team workspace with connectors to banking cores, ERPs and CRMs — targeted at regulated industries such as financial services, government, healthcare and defence. It emerged from stealth in February 2024 with a $3.2M pre-seed led by Felicis; no later round has been announced, and it originally positioned at SMBs before moving upmarket to regulated enterprises.
