Rain

Rain (legal name: Signify Holdings, Inc.) is a global stablecoin infrastructure and card-issuing platform founded in 2021 by Farooq Malik and Charles Naut. The company provides a full-stack API platform that enables fintechs, neobanks, DeFi protocols, and enterprises to launch stablecoin-powered card programs, embedded wallets, on-ramps, and cross-border payment rails — all within weeks rather than months.

Rain's core thesis is rebuilding the financial system's infrastructure using stablecoins as the settlement layer. The company settles directly with Visa in USDC daily (including weekends and holidays), making it the first platform to achieve native stablecoin settlement with a major card network at scale. Rain is a Visa Principal Member, processes over $3 billion in annualized purchases, serves 200+ partners, and operates across 170+ countries.

Core Products

Rain offers a modular, API-first platform with four primary product modules:

• Cards: Global stablecoin-backed Visa card issuance API enabling branded card programs for consumer, corporate, and neobank use cases. Supports USDC, USDT, Apple Pay, and Google Pay across 150+ million merchants in 150+ countries.
• Money-in: Fiat-to-stablecoin on-ramp API that converts local currency to stablecoins instantly via virtual accounts, supporting payroll, contractor payments, earned wage access, and accounts receivable workflows.
• Accounts: Embedded digital wallet API enabling businesses to spin up stablecoin wallets in any app with optional yield functionality, multi-currency funding, and direct card integration.
• Money-out: Stablecoin off-ramp and cross-border payment API for instant global disbursements, remittances, and local currency conversion with 24/7/365 settlement.

Key Strengths

Rain differentiates through its multi-chain architecture — the only platform with active support across Ethereum, Solana, Stellar, Base, Arbitrum, Optimism, and Avalanche. Its modular design lets partners select only the components they need, from card issuing to compliance tooling. The platform maintains SOC 2 compliance, PCI certification, and Sherlock smart contract audits.

Rain also operates Uptop, a loyalty and perks subsidiary integrated into its card programs.

Notable Clients and Partners

Rain's partner ecosystem includes leading Web3 and DeFi platforms such as Avalanche, ether.fi, and Arculus. The company is backed by Coinbase Ventures, Circle, Khosla Ventures, Lightspeed, and Samsung, and has raised a $250M Series C to scale its global payments infrastructure.

Why Choose Rain

Rain is purpose-built for the tokenized money era. Unlike legacy card issuance platforms that require months of integration and operate on traditional rails, Rain enables launch in 6–8 weeks with native stablecoin settlement, built-in KYC/AML, fraud protection, and compliance tooling. Its B2B API-first model makes it the infrastructure layer of choice for any platform seeking to embed stablecoin-powered financial services.
