Sphere Labs
Sphere Labs is a Boston- and Delaware-based fintech building the payments infrastructure for the stablecoin economy. Founded in 2022 by Arnold Lee and Luigi Charles, the company runs two products: SpherePay, a B2B cross-border payments API that moves money using a 'stablecoin sandwich' - converting local currency into a stablecoin, routing it across borders, then settling into the destination currency in 15-30 minutes; and SphereNet, a 'sovereign-grade' settlement ledger built on the Solana Virtual Machine for regulated financial institutions. Often described as a 'Stripe for crypto,' Sphere pairs developer-friendly APIs and SDKs with embedded compliance to help fintechs, institutions and businesses in emerging markets move value fast, transparently and legally. It raised a $5M strategic round in December 2024 led by Coinbase Ventures and Kraken Ventures.
Zerohash
Zerohash is a Chicago-based crypto and stablecoin infrastructure provider that lets banks, brokerages, fintechs and marketplaces embed digital-asset products - trading, payments, stablecoins and tokenization - through a single regulated API. Rather than building blockchain rails, custody and compliance themselves, clients like Stripe, Interactive Brokers, Morgan Stanley and Franklin Templeton plug into Zerohash's licensed, end-to-end platform. Founded in 2017 by Edward Woodford, the company reached unicorn status in 2025 and has settled tens of billions of dollars in volume for millions of end users across nearly 200 jurisdictions.
