HIFI Raises $37M Series A for Stablecoin Settlement

HIFI raised $37 million in a Series A round led by Left Lane Capital, the stablecoin infrastructure startup said Thursday, in what the company described as its first priced funding round. HIFI did not disclose a valuation.

The New York-based company sells API infrastructure that lets businesses move money across stablecoins and traditional bank rails through one integration, rather than stitching together separate providers for each. Chief Executive and co-founder Zach Walsh said in the announcement that the company treats "settlement as one problem, not three," building payments, spending and capital-markets functions on a single layer instead of bolting them together.

What $7 billion in annualized volume looks like

HIFI's infrastructure moves more than $7 billion in annualized transaction volume across 87 countries, according to The Block, which reported the round after the company shared it with the outlet Thursday. HIFI has onboarded more than 10,000 businesses and 200,000 end users, and counts Sumitomo, Dapper and Arival Bank among its customer implementations.

Visa and DTCC are already routing through it

HIFI was one of the participants in DTCC's July production trades using tokenized assets, alongside BlackRock, Goldman Sachs and Nasdaq. In September, the company added a partnership with Visa to extend stablecoin-funded payouts to cards on Visa's network, which The Block reports has more than 4 billion cards issued worldwide.

The comparison puts HIFI's scale in context: Visa's own stablecoin settlement business, which HIFI's card partnership plugs into, already runs at roughly triple HIFI's annualized volume, against a total stablecoin supply The Block put at more than $295 billion.

What HIFI hasn't said

Left Lane Capital managing partner Matthew Miller said the round reflects "the strength of the team and the speed at which stablecoins have become a core part of global financial infrastructure," a line that, like most lead-investor quotes, commits to nothing falsifiable. Neither HIFI nor The Block's writeup names another investor in the round beyond Left Lane, and HIFI has not said how much of its $7 billion in volume is stablecoin-denominated versus traditional bank-rail transfers, a distinction that matters for a company whose pitch is specifically about tokenized settlement.

HIFI's undisclosed valuation puts it alongside other 2026 late-stage rounds that have skipped the number entirely, a pattern also visible in the record 114 Series A rounds of $100 million or more that have closed in 2026, where more than 70 percent of the capital went to AI-related startups without every round naming a price. Databricks' acquisition of spreadsheet startup Row Zero, its fifth deal since March, is a reminder that the same reticence extends to acquirers as well as funders. HIFI's next test is whether the Visa and DTCC partnerships convert into volume it is willing to break out by rail rather than report as a single combined figure.
