Kalto

Kalto was a B2B payments and financing platform headquartered in Mexico City, founded in 2021 and seed-backed by QED Investors. It offered an all-in-one B2B checkout for merchants, distributors, wholesalers, and marketplaces, accepting bank transfers, credit and debit cards, and cash, with an integrated financing product that let merchants extend net payment terms (15/30/45 days) to their business buyers. In April 2025 Kalto was acquired by Tiendanube (Nuvemshop) to power "Pago Nube," a native embedded checkout and financial-services experience for Tiendanube merchants in Mexico. As of this profile the standalone kalto.la domain no longer resolves to a company site (it redirects to unrelated parked pages) and Kalto publishes no public developer portal, API documentation, or OpenAPI, so there is no live API surface to enrich.

Kalto is profiled on the APIs.io network. Tagged areas include Company, Payments, Fintech, B2B, and Checkout.
