Streamex Corp., formerly BioSig Technologies, has pivoted from a legacy medical-device focus to a dual business model centered on tokenized finance and electrophysiology technology. Through its 2025 acquisition of Streamex Exchange, the company is building an institutional-grade platform to tokenize real-world assets, starting with gold.
The new GLDY gold-backed digital token represents fractional interests in a Cayman SPV that holds vaulted gold and participates in gold leasing, with subscriptions now open to accredited and qualified investors. To fund this strategy, Streamex completed a $40.25 million underwritten equity offering in early 2026 and put in place a secured convertible debenture facility with Yorkville, issuing two $25 million tranches in late 2025 before fully repaying them in February 2026.
The company continues to own majority stakes in ViralClear and BioSig AI and holds an extensive patent portfolio around its PURE EP cardiac signal processing platform, though these healthcare businesses are no longer its primary strategic focus.
