HIFI Secures $37M Series A From Left Lane Capital To Scale $7B Stablecoin Payments And Tokenized Markets

HIFI raised a $37 million Series A led by Left Lane Capital on September 24, 2026, to scale its stablecoin payments and tokenized capital markets infrastructure. The New York-based company disclosed the financing in a press release provided to The Block, describing the round as its first priced equity financing and positioning the capital as fuel for expanding licensing, card issuance, and settlement rails as Wall Street institutions move onchain.

CEO Zach Walsh said the platform currently handles approximately $7 billion in annualized direct transactions, a figure that anchors the company's pitch to institutional clients and enterprise partners. The round arrives as stablecoin infrastructure draws concentrated venture attention, with cross-border stablecoin flows growing 77.5% to $220.3 billion in the year to June 2026, according to Chainalysis data cited in coverage of the raise.

Left Lane Capital Leads $37M Round As HIFI Expands Stablecoin Payments And Cards

Left Lane Capital led the Series A, with Antler among the participating investors, according to a blog post from Antler explaining its decision to back the company. The round's structure and valuation were not disclosed in the initial announcement, leaving open questions about HIFI's post-money position and the full investor syndicate. StrictlyVC described HIFI as a four-year-old New York startup, a detail that frames the Series A as a maturation milestone rather than an early-stage experiment.

The financing will support the scaling of HIFI's tokenized capital markets infrastructure and the expansion of its broader product suite, according to the company's statement. HIFI's API architecture combines regulatory compliance, fund transfers, and settlement functionality into a single integration point, a design intended to reduce the operational burden for institutions moving between fiat and stablecoin rails. The company said the capital will be directed toward expanding that infrastructure alongside a broader offering of products, though it did not specify which products would launch first.

The Block Reports The September 24 Announcement

The Block reported the financing on Thursday, September 24, 2026, citing the company's press release. HIFI framed the round as a response to accelerating institutional adoption of tokenized settlement, with the company positioning itself as a bridge between traditional banking rails and blockchain-based capital markets infrastructure. The announcement did not include a valuation figure, and HIFI has not disclosed whether the round included secondary share sales or was entirely primary capital.

Antler Explains Its Participation

Antler published a post explaining why it invested in HIFI's $37 million Series A, describing the company as building infrastructure to power entirely new financial products with stablecoins across payments, card issuance, and capital markets. The post signals that the round attracted both growth-stage and early-stage investors, with Left Lane Capital anchoring the deal and Antler adding strategic support. The full list of participating investors remains undisclosed beyond these two names.

HIFI's Stablecoin Payments And Tokenized Capital Markets Infrastructure Explained

HIFI operates as a financial infrastructure company for stablecoin payments and tokenized assets, providing a composable API that lets clients move money across stablecoin rails, bank rails, and card rails. The platform supports the inflow and outflow of funds between US dollars and stablecoins, dispatches payouts through the American banking system and bank cards, and provides US dollar cash settlement services for token-based repurchase agreements and US Treasury bond transactions. That settlement capability places HIFI at the intersection of two converging trends: stablecoin adoption for payments and tokenization of traditional fixed-income instruments.

The company participated in production and trading testing of tokenized securities conducted by the Depository Trust and Clearing Corporation, the US market infrastructure that clears and settles the vast majority of domestic securities transactions. That participation, reported by The Block, gives HIFI a credential that matters to institutional clients evaluating whether a startup can handle regulated settlement workflows. HIFI also moved from pilot to production on Canton, the privacy-enabled blockchain network built by Digital Asset, according to the Canton Weekly News newsletter.

Dfns Partnership Adds Wallet Infrastructure

HIFI partnered with Dfns to combine programmable money infrastructure, with Dfns bringing wallet infrastructure to HIFI's platform and HIFI providing stablecoin and bank rail connectivity to Dfns' Payouts and Payins APIs. The partnership, announced on LinkedIn, extends HIFI's reach into developer-facing payment tooling and suggests the company is building toward a broader programmable payments ecosystem rather than a single vertical product.

Compliance Architecture Targets Institutional Clients

HIFI built compliance into its stablecoin infrastructure from the ground up, according to a TRM Labs post describing the company's approach to institutional clients. The company operates as a money services business serving institutional counterparties, with bank-grade compliance embedded in its payment flows. Sumsub described HIFI as a programmable payments and stablecoin infrastructure platform that unifies US regulatory requirements, a positioning that matters as stablecoin issuers and payment processors face tightening oversight.

Left Lane Capital's Fintech Investment Strategy And Stablecoin Focus

Left Lane Capital is a New York-based growth equity firm with a portfolio concentrated in consumer and fintech companies, including Bilt Rewards, Lemfi, Kast, M1 Finance, Wayflyer, Talkiatry, and Blank Street. The firm's investment in HIFI extends a pattern of backing companies that sit between traditional financial infrastructure and emerging payment rails, with Kast specifically operating in the stablecoin payments space. Left Lane's participation as lead investor signals conviction that stablecoin settlement infrastructure has reached a stage where venture-scale returns are plausible.

The firm's broader portfolio spans creator tools, audio platforms, and private markets technology, with F2, an AI platform for private credit investors, backed by NFX, Left Lane Capital, and Y Combinator. That diversity suggests Left Lane evaluates HIFI through a fintech infrastructure lens rather than a pure crypto thesis, treating stablecoin rails as a payment technology that can serve existing financial workflows. The HIFI deal fits a strategy of backing companies that reduce friction in money movement, whether through rewards programs, cross-border remittances, or tokenized settlement.

Stablecoin Portfolio Signals Sector Conviction

Left Lane's existing position in Kast, which raised $80 million in Series A funding to connect real-world stablecoin payments, demonstrates the firm's willingness to make concentrated bets on stablecoin infrastructure. The HIFI investment adds a second stablecoin-focused company to the portfolio, suggesting Left Lane sees the sector as large enough to support multiple winners across different layers of the stack. The firm has not published a formal investment thesis for HIFI, but the round's structure as a priced Series A indicates a growth-stage valuation rather than a seed-stage experiment.

How HIFI's $37M Round Compares With Other Stablecoin Infrastructure Fundraises In 2026

HIFI's $37 million Series A ranks among the larger stablecoin infrastructure raises of 2026, though it trails Kast's $80 million Series A in the same category. The comparison is imperfect because Kast operates a consumer-facing stablecoin payment product while HIFI sells infrastructure to enterprises and institutions, but both companies are competing for the same underlying market: businesses and consumers moving value across stablecoin rails. The Onchain Daily Wrap newsletter for September 25, 2026, described HIFI's round as one of the bigger recent raises in the tokenized settlement category.

The broader funding environment for stablecoin infrastructure remains active, with Stripe, Visa, and Mastercard reportedly backing a new stablecoin platform as of June 2026, according to SpendNode. That report pegged the combined stablecoin market cap at around $325 billion as of June 3, 2026, a figure that contextualizes the commercial opportunity HIFI is pursuing. Crypto card spending surged 500% to $600 million monthly by 2026, according to Yahoo Finance, indicating that the card issuance component of HIFI's roadmap addresses a rapidly expanding market.

Tokenized Capital Markets Attract Institutional Attention

The tokenized capital markets segment is drawing attention from major financial institutions, with BlackRock CEO Larry Fink using his 2026 annual letter to argue that tokenization will update the entire financial system. The House Financial Services Committee examined tokenization in a hearing, with exchanges, market operators, and regulators pushing ahead on the technology. HIFI's participation in DTCC's tokenized securities testing places it within this institutional adoption narrative, though the company has not disclosed revenue or profitability figures that would allow direct comparison with public market infrastructure providers.

What HIFI Plans To Build Next With The New Capital

HIFI said the Series A capital will support expansion of its licensing footprint, card issuance capabilities, and capital markets infrastructure, according to Noya Crypto's coverage of the round. The company has not specified which regions it will target first, though its existing operations in New York and its participation in US market infrastructure testing suggest a domestic focus in the near term. The licensing expansion implies HIFI intends to secure additional money transmitter licenses or similar regulatory approvals across multiple states, a process that consumes significant capital and time.

The company's roadmap includes deeper integration with tokenized repurchase agreements and Treasury bond settlement, building on its existing US dollar cash settlement services. HIFI's move from pilot to production on Canton indicates that onchain repo and Treasury settlement are near-term priorities, with the June 17, 2026 announcement that HIFI, DRW, and Marex advanced onchain repo on the Canton Network serving as evidence of active institutional engagement. The Nasdaq press release for that initiative described HIFI as providing the platform that enables financial institutions and enterprise clients to issue, move, and settle cash, collateral, and assets.

Card Issuance And Programmable Payments

The card issuance component of HIFI's roadmap aligns with the 500% surge in crypto card spending to $600 million monthly by 2026, a market signal that suggests consumer demand for stablecoin-backed spending products is accelerating. HIFI's existing card rails integration positions the company to serve fintech clients that want to issue stablecoin-linked cards without building their own banking relationships. The company has not announced specific card partnerships tied to the Series A, leaving the timing and scope of new card products undisclosed.

Open Questions On Valuation And Syndicate

HIFI has not disclosed its post-money valuation following the Series A, and the full investor syndicate beyond Left Lane Capital and Antler remains unknown. The company described the round as its first priced financing, which means earlier capital came through convertible instruments or other structures that did not establish a formal valuation. Those open questions matter for competitive benchmarking, but they do not change the core signal: a growth-stage firm with $7 billion in annualized transaction volume has secured institutional backing to expand its infrastructure as stablecoin adoption accelerates.
