Vultr

Vultr is the flagship product of Constant, founded by David Aninowsky, and launched in 2014 as a developer-focused cloud built on a wide footprint of data centers spanning six continents. The company stayed bootstrapped and self-funded for roughly a decade, growing into one of the largest privately held cloud infrastructure providers, before taking its first outside equity in December 2024: a $333 million round at a $3.5 billion valuation led by LuminArx Capital Management with AMD Ventures participating. Vultr now pairs its broad-reach IaaS with a Cloud GPU business targeting AI training and inference: it secured a $329 million credit facility in June 2025, and in December 2025 was reported to be building a $1 billion-plus, 50MW cluster in Ohio with roughly 24,000 AMD MI355X GPUs.
