“Can a website-builder-turned-commerce-platform become the financial operating system for independent small businesses by layering payments, lending, and banking onto its existing customer relationships?”
Founded in 2003 as a bootstrapped website builder, Squarespace expanded into e-commerce in 2013 and built a multi-product SaaS platform serving millions of small businesses globally. After its 2021 direct listing and subsequent 2024 take-private by Permira, the company has been systematically layering embedded finance products — Payments, Capital, and Balance — on top of its existing commerce infrastructure, mirroring Shopify's playbook almost exactly but following several years behind. Stripe underpins the entire financial stack (payments, treasury, issuing, and capital), while lending partners Celtic Bank (US) and YouLend (UK) provide the regulated credit product.
Squarespace discloses Stripe Treasury as its banking provider, with Celtic Bank as its sponsor bank, according to the Embedded Finance Index 2026.
Squarespace does not disclose a bank charter of its own; its banking services are provided through Celtic Bank.
Squarespace processes payments through Stripe, Square, PayPal and Squarespace Payments (self-operated).
Squarespace's cards are issued through Stripe Issuing on the Visa network.
Squarespace's lending and capital products are provided by Stripe Capital and YouLend.
Squarespace integrates with QuickBooks Online, Xero and MYOB.
