Harbour Industrial Capital’s lead investment into Joinn, Backing Growth of Next-Generation RWA Platform

Hong Kong / Cayman Islands – October 9, 2025 – Harbour Industrial Capital (HIC) today announced its lead investment into Joinn through its second fund, HIC Fund II LP. The funding marks a significant step in Joinn’s growth as it expands access to tokenized financial assets for underserved populations worldwide. 

The investment is part of Joinn’s transition to Polkadot Hub, taking advantage of Polkadot’s state of the art security architecture.

Joinn.io is a fintech platform that makes investing and spending seamless by combining blockchain infrastructure with a Web2-style user experience. Through its app and Mastercard-powered card, users can buy and hold assets like U.S. Treasury Bills, ETFs, and REITs, while enjoying 24/7 liquidity and compounding yield. By aggregating tokenized assets in one jurisdiction and distributing them globally, Joinn ensures users everywhere can access financial products traditionally restricted to a few markets. Its mission is to democratize wealth-building tools that are typically unavailable in regions such as Latin America, where investment penetration remains below 5 percent compared to over 40 percent in the United States.

The investment will fuel Joinn’s next phase of growth, including product development, geographic expansion, and user acquisition.

“We are excited to back Joinn at this stage of their journey,” said Mario Altenburger, Co-founder and CIO of Harbour Industrial Capital. “Joinn’s approach to democratizing access to real world assets through a simple, transparent, and blockchain-enabled platform is exactly the kind of financial innovation we believe will define the next decade. Its mission aligns with our view that Web3 infrastructure should empower real people with practical tools.”

With HIC’s support, Joinn.io is preparing to scale its “invest-while-you-spend” ecosystem and deliver meaningful impact for users across emerging markets. Key milestones ahead include market launches in new regions, expanded product features, and partnerships that deepen liquidity and accessibility.
