- The platform offers up to 8% annual percentage yield and up to 3% cashback, while regulated financial services are provided through licensed partners.
- After raising $80 million at a reported $600 million valuation, Kast aims to onboard between 1,000 and 5,000 active businesses by the end of 2026 overall.
Kast has launched KAST Business, a stablecoin-powered platform combining business accounts, payment cards, cross-border transfers and yield-bearing balances for companies. Businesses can receive funds through fiat virtual accounts supplied by regulated partners, deposit supported stablecoins and crypto, issue virtual cards and make local payouts in more than 20 currencies. The central proposition is to package stablecoin infrastructure into a familiar business-finance experience rather than expose companies to fragmented crypto tools. Kast says it serves more than 170 countries, although availability depends on jurisdiction, giving the platform an unusually broad intended footprint from launch.
Stablecoin Rails Move Deeper Into Business Finance
The platform also adds incentives designed to make idle corporate balances more productive. Kast advertises up to 8% annual percentage yield, generated through short-term U.S. Treasurys and stablecoin yield, alongside up to 3% cashback on purchases. That combination turns the product into more than a payments layer by pairing transaction tools with balance-sheet returns and spending rewards. Yet Kast is not a bank. It operates as a financial technology company, with regulated services delivered through licensed partner institutions, an important distinction for businesses evaluating where their funds and payment services ultimately sit.
The launch follows Kast’s $80 million funding round in March, which reportedly valued the company at $600 million. Kast said the capital would support product development, licensing and expansion across North America, Latin America and the Middle East. The new business platform shows how that funding is being converted into a broader commercial push rather than remaining focused on consumer stablecoin services. The company also hired former U.S. Securities and Exchange Commission adviser Stephanie Allen to lead policy communications as it prepared the rollout, linking product expansion with a more deliberate regulatory and policy strategy.
Kast claims more than 1 million users and now wants to onboard between 1,000 and 5,000 active businesses by the end of 2026. That target will test whether companies are ready to adopt stablecoin rails for everyday treasury and payment workflows, not merely crypto trading. The bigger question is whether stablecoins can become invisible infrastructure for routine business banking while regulated partners handle the licensed financial functions underneath. If Kast can convert its consumer scale into meaningful business adoption, KAST Business could provide a practical test of how stablecoin-based accounts, cards and international payments compete with conventional fintech offerings globally.
