Auradine, a California-based manufacturer of bitcoin mining hardware, has closed a $153 million Series C funding round, signaling a period of significant growth and expansion. The investment will fuel both the company’s core bitcoin mining operations and its newly launched AI infrastructure division, AuraLinks AI. The financing was led by StepStone Group, with participation from notable venture capital firms such as Maverick Silicon, Premji Invest, Samsung Catalyst Fund, Qualcomm Ventures, Mayfield, MARA Holdings, GSBackers, and other existing investors. The fundraising process took place throughout late 2024 and concluded earlier this month, exceeding the initial target of $125 million by over 22%.
