Jai Patel has stepped down as chief executive of Stack BTC, a UK-listed bitcoin treasury company that attracted attention earlier this year when Reform UK leader Nigel Farage and former chancellor Kwasi Kwarteng became early shareholders. The company — originally founded by Patel in 2021 as Kasei Investment Holdings, a cryptocurrency investment firm that was liquidated last year after returning roughly half its initial capital to shareholders — was relaunched in March 2025 under the Stack BTC name, with a new focus on accumulating bitcoin and acquiring smaller companies. Stack BTC said Patel's departure, effective immediately, was part of efforts to "deliver long-term value for shareholders," and announced his replacement by David Galan, a former real estate executive with a background in capital markets and mergers and acquisitions.
