Cast AI, the leading Kubernetes automation platform, announced it has closed a $108 million Series C funding round, finalized on May 1, 2025. The round was led by G2 Venture Partners and SoftBank Vision Fund 2, with new investor Aglaé Ventures—the venture arm of Bernard Arnault, chairman and CEO of LVMH—joining alongside existing partners Hedosophia, Cota Capital, Vintage Investment Partners, Creandum, and Uncorrelated Ventures.
The oversubscribed round, marked by a substantial valuation step-up, reflects Cast AI’s rapid revenue growth and escalating market demand. Several participants in this round are also investors in AI leaders such as OpenAI and Crusoe.
Originally recognized for reinventing Kubernetes automation, Cast AI is now expanding its mission by pioneering Application Performance Automation (APA). This next-generation platform goes beyond observability, using real-time performance signals to autonomously optimize cost, security, and speed across any cloud environment.
“APA didn’t exist five years ago, because we hadn’t invented it yet,” said Yuri Frayman, CEO and co-founder of Cast AI. “This round fuels our continued expansion of a category we created and pushes the boundaries of what’s possible in cloud automation.”
Cast AI’s innovation continues to drive global momentum. Between 2023 and 2024, the company doubled its customer base and now serves over 2,100 organizations worldwide, including Akamai, BMW, FICO, HuggingFace, NielsenIQ, and Swisscom. It also broadened its international footprint with new offices in India and Singapore, and earned recognition as both an IDC Innovator and G2 Cloud Cost Management Leader.
“Enterprises are no longer satisfied with static dashboards and manual tuning knobs,” said Leon Kuperman, CTO and co-founder. “They want automation that works out of the box and gets smarter over time. APA is the answer—and this funding accelerates that promise.”
Findings from the 2025 Kubernetes Cost Benchmark Report by Cast AI reveal that only 10% of CPUs and 23% of memory are utilized across cloud environments—highlighting widespread inefficiencies. APA addresses this gap with automated capacity management, delivering both immediate cost savings and performance gains.
“Cast AI is setting a new standard for cloud efficiency as infrastructure demands surge,” said Tim Yap, Investment Director at SoftBank Investment Advisers. “We’re proud to support their mission to power AI workloads at scale with intelligent automation.”
“Cast AI plays a critical role in the modern cloud stack,” added Jake Tauscher, Partner at G2 Venture Partners. “It improves cost, performance, sustainability, and productivity—making it an essential partner to today’s enterprises.”
“With APA, organizations can now deploy hyper-efficient GPU instances instantly,” said Laurent Gil, President and co-founder of Cast AI. “We’re proud to partner with SoftBank to unlock AI’s full potential through automation.”
