Startale Group has closed a $63 million Series A backed by SBI Group and Sony Innovation Fund, positioning the Web3 infrastructure company at the center of Japan’s institutional push into tokenized securities and stablecoin rails.
A Japanese mega-bank and a global entertainment conglomerate writing nine-figure checks into a single Web3 infrastructure stack is not a coincidence. It is a capital concentration signal.
Key Takeaways:
Round Size: Startale closed a $63 million Series A in two tranches — a $13 million first close from Sony Innovation Fund and a $50 million second close from SBI Group.
Lead Investors: SBI Group, one of Japan’s largest financial conglomerates with access to over 80 million customers, anchored the round alongside Sony, with whom Startale co-developed Ethereum Layer 2 Soneium.
Strategic Context: Capital goes directly toward scaling Strium (a Layer 1 for tokenized securities), expanding JPYSC and USDSC stablecoins, and building a consumer SuperApp — a full-stack institutional and retail Web3 infrastructure play.

SBI Group’s $50 million second close is the dominant force in this round. SBI is not a passive financial sponsor, it is a strategic co-builder.
The two companies have already shipped Strium, a Layer 1 blockchain built specifically for tokenized securities and real-world asset trading, and JPYSC, described as the first trust bank-backed Japanese yen stablecoin.
SBI Chairman Yoshitaka Kitao said Startale “possesses extensive expertise in the field of on-chain integration and offers capabilities that complement those of the SBI Group,” framing the investment as vertical integration in digital finance rather than a passive bet. Startale also unveiled USDSC, a dollar-pegged stablecoin designed to enable fiat-to-crypto integration, onchain dividends, and yield distribution for both retail and institutional users.
Sony’s $13 million first close, announced previously, originated from the companies’ existing collaboration on Soneium — Sony’s Ethereum Layer 2 — developed through Sony Block Solutions Labs. Fresh capital will also fund an upgrade of the Startale App into a SuperApp running on Soneium, integrating tokenized assets, stablecoins, payments, Mini Apps, and social features into a single consumer interface.
CEO Sota Watanabe said the round “reflects the strong conviction our partners have in the vision we are building,” adding that the SBI collaboration will “accelerate the adoption of tokenized stocks, centered on Japanese equities and JPY stablecoin, this year.”
