CRASSULA launches BaaS stack

Crassula is pitching banks and fintechs a prebuilt banking stack that lets them launch branded accounts, cards, and payments without building the rails themselves. (crassula.io) Banking-as-a-service means one company supplies the plumbing — accounts, payments, compliance checks, and card connections — while another puts its own brand on the customer app. Crassula says its white-label platform can be rolled out in 10 business days and already connects to more than 60 services. (help.crassula.io, crassula.io) The company’s current product pages describe a full package: International Bank Account Number accounts, local and international payments over networks including Single Euro Payments Area and SWIFT, plus virtual and physical card programs. Its help center says the stack supports Visa and Mastercard integrations. (help.crassula.io, crassula.io) Crassula also bundles foreign exchange and crypto tools into the same system. The company says clients can offer fiat-to-crypto exchange, custody-connected wallets, transaction monitoring, and branded crypto products from one back office. (help.crassula.io, crassula.io) That pitch lands as more fintech infrastructure vendors try to sell “one integration” instead of a patchwork of bank, card, and compliance vendors. Crassula’s FinTech Hub page says customers can connect to multiple providers through a single application programming interface rather than integrating each partner one by one. (crassula.io) The target buyers are not just startups. Crassula says its software is built for digital banks, e-wallets, crypto firms, foreign-exchange platforms, payment institutions, and embedded-finance providers that want branded products without building core systems from scratch. (help.crassula.io, crassula.io) Compliance is part of the sales pitch because these products sit inside regulated payments flows. Crassula’s help center says the platform includes know-your-customer, know-your-business, anti-money-laundering, and transaction-monitoring tools, and the company added tell.money in March 2025 to help clients meet open-banking and Confirmation of Payee requirements tied to PSD2 rules. (help.crassula.io, thepaypers.com) Crassula has been assembling this stack in pieces for years through provider partnerships. Its Railsr solution page advertises virtual International Bank Account Number generation, Single Euro Payments Area, ACH, Faster Payments, foreign exchange, and Visa and Mastercard card issuing through one core-banking back office. (crassula.io) The company is also leaning harder into digital assets. WhiteBIT said in December 2025 that it became one of Crassula’s digital-asset connectors, part of a broader push to combine payments, accounts, cards, foreign exchange, and crypto through a single interface. (blog.whitebit.com) Crassula says more than 150 companies already use its software. The launch pitch is straightforward: sell the bank in a box, let the customer own the brand, and keep the infrastructure underneath. (crassula.io, crassula.io)
