HIFI Secures $37 Million in Series A Funding

New York-based HIFI, an API platform specializing in stablecoin payments and settlement, has raised $37 million in a Series A funding round. According to THE BRIDGE, the round was led by Left Lane Capital, with participation from Tether, the issuer of the USDT stablecoin, and global early-stage venture capital firm Antler.

Investors and Platform Growth

Antler, which also invested in HIFI’s pre-seed and seed rounds, joined the Series A as a follow-on investor. The funding round reflects growing confidence in HIFI’s infrastructure, which reportedly exceeds $7 billion in annualized processing volume. The platform has onboarded over 10,000 businesses and 200,000 individuals across 87 countries.

Key Features and Institutional Use Cases

HIFI’s platform consolidates funds transfer, programmable control, compliance, and settlement into a single integration, supporting stablecoins, banks, and payment networks. One of its notable features, 'Push to Card,' allows U.S. businesses to instantly transfer stablecoin balances to Visa debit or credit cards.

Beyond retail applications, HIFI’s infrastructure has been adopted in institutional contexts. According to THE BRIDGE, the platform was used in a tokenized repo proof-of-concept by the Depository Trust & Clearing Corporation (DTCC). It also facilitated a tokenized repo transaction between DRW and Marex on Tradeweb, where the cash leg was settled using USDCx on the institutional blockchain Canton Network.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

HIFI’s Series A funding underscores the increasing institutional appetite for stablecoin-based payment rails. While stablecoins have often been associated with retail transactions, HIFI’s involvement in tokenized repo transactions signals their potential to reshape institutional settlements. For founders and operators, this round highlights two trends: the maturation of blockchain-based financial infrastructure and the demand for seamless integration between traditional and digital assets. The participation of Tether, a dominant player in the stablecoin space, further validates this direction. However, regulatory uncertainty remains a hurdle for widespread adoption, particularly in markets with stringent financial oversight.

Key takeaways

• HIFI’s Series A funding highlights growing institutional interest in stablecoin payment infrastructure.
• The platform’s ability to integrate stablecoins, banks, and payment networks positions it as a key player in fintech innovation.
• Tokenized repo transactions demonstrate HIFI’s utility in institutional financial workflows.
