What Comino does

Comino is a London-headquartered, privately held manufacturer of liquid-cooled GPU computing infrastructure, founded in 2017 and operating across the UK, Latvia, USA, and China with 51–100 employees. The company's core technology is a proprietary closed-loop liquid cooling system that simultaneously cools GPU, VRAM, and VRM components, paired with TheQ quick-disconnect couplings that allow component swaps without draining coolant. Its flagship Grando product line comprises silent multi-GPU workstations (up to 4 GPUs) and performant multi-GPU servers (up to 8 GPUs) supporting the latest NVIDIA (H100, H200, RTX PRO 6000 Blackwell, RTX 5090, DGX Spark) and AMD (EPYC, Radeon PRO W7900) hardware, complemented by a component ecosystem including custom copper waterblocks, an Integration Kit for retrofitting air-cooled servers, Comino Energia PSUs, and a Grando mobile data center.

Comino monetizes primarily through hardware sales — Grando systems priced on request, GPU waterblocks (€800+), integration kits, and PSUs — supplemented by extended warranty subscriptions (5% per year for years 3–5), managed FPGA co-location services (€6,365–€6,480/year in a Sweden data center), and OEM/ODM design services. It also sells the Comino Cosmos AI Assistant software platform, an agentic 'AI Employees' product launched in 2026. Distribution is hybrid: direct online sales through comino.com plus an online Grando configurator, alongside a channel network spanning Puget Systems (US), PNY Technologies (EMEA), mh-Service (Germany), Teel Technologies Canada (forensics), and a strategic ModulEdge partnership for turnkey modular data center deployments across Europe and MENA. Customers span AI/ML organizations, digital forensics/law enforcement, CG and virtual production studios (e.g., powering Netflix's Motorvalley via Luno Studios), life science research institutions, and high-frequency trading firms.

Comino holds AMD Partner Program Elite status and partners directly with NVIDIA, with active presence at COMPUTEX Taipei, NVIDIA GTC, Hannover Messe, ISS World Europe, and GPEC. The company has raised approximately $1.18M via Seedrs (December 2020), its only disclosed funding round, and is targeting the projected market shift toward liquid cooling adoption in AI servers (cited as moving from 15% in 2024 to 76% by end of 2026 by Goldman Sachs).
