In late 2025, Mark Karpelès, ex CEO of Mt. Gox, lives a quieter life in Japan, building a VPN and an AI automation platform. As Chief Protocol Officer at vp.net—a VPN that uses Intel’s SGX technology to let users verify exactly what code runs on servers—he works alongside Roger Ver and Andrew Lee, the founder of Private Internet Access. “It’s the only VPN that you can trust basically. You don’t need to trust it, actually, you can verify”. At shells.com, his personal cloud computing platform, he’s quietly developing an unreleased AI agent system that hands artificial intelligence full control over a virtual machine: installing software, managing emails, and even handling purchases with a planned credit card integration. “What I’m doing with shells is giving AI a whole computer and free rein on the computer”, a brilliant idea, really. AI agents on steroids.
Released on bail after disproving key charges, Karpelès was convicted only on lighter record-falsification counts at the end of the ordeal. The Silk Road links had complicated perceptions, with Ross Ulbricht’s defense briefly attempting to implicate him to create plausible deniability for Ulbricht. Public narratives often painted him as complicit in Bitcoin’s dark side, despite his policies against it.
Emerging in 2016, rumors swirled of vast personal wealth from Mt. Gox’s remaining assets—once estimated at hundreds of millions or even billions due to Bitcoin’s price surge. Yet Karpelès says he receives nothing. The bankruptcy’s pivot to civil rehabilitation allowed creditors to claim in bitcoins, distributing value proportionally. I like to use technology to solve problems, and so I don’t really even do any kind of investment or anything like that because I like to make money by constructing things. To just get a payout for something that’s essentially a failure for me would feel very wrong, and at the same time, I’d want customers to get the money as much as possible.” Creditors, many now receiving far more in dollar terms due to Bitcoin’s rise, continue waiting.
Today, Karpelès collaborates with Roger Ver—the early visitor turned business partner—who recently settled U.S. tax claims for nearly $50 million. “I’m happy for him that he’s finally getting things cleared,” Karpelès said.
Today, Karpelès says he owns no bitcoin personally, though his businesses accept it as a form of payment. Discussing the current state of Bitcoin, he critiqued centralization risks in ETFs and figures like Michael Saylor: “This is a recipe for catastrophe… I like to believe in crypto in mathematics and different things, but I don’t believe in people”. On FTX: “They were running accounting on QuickBooks for a potentially multi-billion dollar company, which is crazy”.
From Bitcoin’s epicenter—hosting Silk Road links, onboarding the world, enduring Japan’s harshest detention—to building verifiable privacy tools, Karpelès’ arc reflects the industry’s maturation. His story marks the first roar of Bitcoin into mainstream culture, a time when his leadership as CEO of Mt. Gox placed him at the center of the storm. Clearest of all, his builder mindset remains a great example of the type of engineer and entrepreneur attracted to Bitcoin in those early days.
