About
Maybell Quantum, founded in 2021 in Colorado, provides quantum infrastructure, including advanced dilution refrigerators built for improved reliability and user experience. The company exited stealth in 2022 with its Icebox cryogenic dilution refrigerator, now called The Fridge, and followed it in 2023 with the larger Big Fridge, which offers double the cooling capacity. It also provides advanced wiring solutions that reduce thermal load and footprint. In September 2025, Maybell secured $40 million in Series B funding led by Addition, bringing total funding to $65 million. In 2025, the company partnered with Entanglement Inc. for cryogenic systems in quantum laboratories. In March 2026, Maybell unveiled ColdCloud, a scalable cryogenic cooling platform that uses 90% less electricity, 90% less cooling water, and up to 80% less helium-3 per qubit than legacy systems. Its proprietary 'Maybell-cycle' cuts cooldown from days to hours. ColdCloud distributes cooling from a central source to independent nodes that can be configured below 10 mK for superconducting qubits, with the first system scheduled to come online later in 2026. Update 2026-03-12: Maybell Quantum announced ColdCloud, a scalable cryogenic cooling platform designed to improve quantum computing efficiency.
