HIFI Lands $37M Series A Led By Left Lane Capital For Stablecoin Payments

Crypto and blockchain companies raised more than $104.2 million across eight disclosed financings during the week of September 19-25, 2026, according to a compilation of venture capital announcements. The weekly total was led by HIFI's $37 million Series A, the largest single round of the period, followed by Atum's $13.5 million financing. The remaining six disclosed rounds were smaller in size, though specific amounts and company names were not fully detailed in the aggregate data.

HIFI, a New York-based stablecoin infrastructure company, closed a $37 million Series A round, marking its first priced funding milestone. The round was led by Left Lane Capital, according to a Chainwire announcement dated September 24, 2026. CEO Zach Walsh revealed the deal to Cointelegraph, noting that while the company has not disclosed its valuation, the capital will accelerate HIFI's expansion into stablecoin payments and tokenized markets worldwide. HIFI processes approximately $7 billion in transactions annually and participated in the DTCC's first tokenized collateral transaction.

Atum raised $13.5 million in seed funding during the week of September 19-25, 2026, with Variant and PayPal Ventures participating in the round. The financing is directed toward building an open financial infrastructure platform, according to coverage from buildersinfintech.ai. The participation of PayPal Ventures, a corporate venture arm with significant fintech expertise, suggests strategic interest in Atum's infrastructure approach.

The concentration of disclosed capital in the two largest rounds—HIFI's $37 million and Atum's $13.5 million, together representing roughly 48% of the weekly total—indicates that the remaining six financings averaged approximately $8.95 million each. This distribution suggests a mix of early-stage seed rounds and mid-sized Series A investments across the crypto and blockchain sector during the September 19-25 window.
