Venture investment in blockchain and artificial-intelligence firms accelerated on 17 June, with four start-ups announcing a combined US$41 million in fresh capital. Stablecoin-clearing platform Ubyx raised US$10 million in a seed round led by Galaxy Ventures, drawing support from Founders Fund, Coinbase Ventures, VanEck, Mirana and Paxos. Founded by former Citigroup executive Tony McLaughlin, the company plans to launch by year-end with a network designed to streamline transfers of stablecoins across platforms such as Solana, Base, Canton and XRPL. Generative-AI outfit PrismaX secured an US$11 million seed investment headed by Andreessen Horowitz’s crypto arm, with Volt Capital and Stanford SBA among the backers. The firm is developing visual and robotic AI models aimed at accelerating the adoption of robotics. PublicAI, which operates a decentralised marketplace for AI data annotation, said it has now raised US$10 million from investors including STC, The BB Fund and NEAR Foundation, broadening a previously disclosed US$8 million Series A. The company is integrating its “human layer of AI” service into the NEAR ecosystem. Gradient, building a decentralised AI runtime on Solana, obtained US$10 million in seed funding from Pantera Capital and Multicoin Capital. The cluster of deals underscores sustained investor appetite for projects at the intersection of cryptocurrency infrastructure and artificial intelligence.
