Mesta (operated by Fortull Inc. in the U.S., doing business as MESTA) is a global fiat-and-stablecoin operating system built to help businesses store, grow, move, and spend money across any currency and any payment rail, anywhere in the world. Its core positioning is unifying traditionally fragmented financial infrastructure — bank rails, stablecoins, and blockchain networks — into a single API-driven platform, live across more than 40 fiat currencies and 13 general-availability payment corridors, with roughly 24-hour KYB (Know Your Business) onboarding.

The platform's product suite is organized around four functions. Under "Store," Mesta offers Virtual Accounts (named accounts in USD, EUR, GBP, and MXN that let businesses collect funds globally without opening local entities) and Self-Custody Wallets for holding stablecoins across multiple blockchains. Under "Grow," an upcoming Stablecoin Yields product will let businesses earn on idle reserves without moving funds elsewhere. Under "Pay/Spend," Mesta provides cross-border Payments (first- and third-party, across both fiat and stablecoins), On-ramps (fiat to stablecoin) and Off-ramps (stablecoin back to bank accounts), Fiat-to-Fiat Transfers spanning 40+ currencies, and upcoming Stablecoin Cards for global spending. The company also markets Agentic Payments infrastructure and White Label offerings for partners wanting to embed Mesta's rails under their own brand.

Mesta targets five specific industry segments: Money Services Businesses (MSBs) and Payment Service Providers (PSPs), fintech SaaS platforms, trade aggregators and e-commerce companies, global payroll platforms, and global treasury management operations — essentially any business needing to move money across borders efficiently. The company emphasizes real-time settlement in key markets, FX savings of 30–70% by cutting out intermediaries, and compliance built in from day one, including KYB, AML, and sanctions screening across every transaction flow.
