Maybell Quantum

Maybell Quantum, founded in 2021 in Colorado, provides next-generation quantum infrastructure including advanced dilution refrigerators designed for improved reliability and user experience. In September 2025, the company secured $40 million in Series B funding led by Addition, bringing total funding to $65 million. Maybell exited stealth in 2022 with its Icebox (now 'The Fridge') cryogenic dilution refrigerator, followed by the larger Big Fridge in 2023 offering double the cooling capacity. The company also provides advanced wiring solutions that reduce thermal load and footprint. In 2025, Maybell partnered with Entanglement Inc. for cryogenic systems in quantum laboratories. Their redesigned dilution refrigerators address key reliability challenges faced by quantum computing companies and research institutions requiring ultra-low temperature environments for superconducting and other qubit technologies.
