Sweepbase careers

Sweepbase is a free crypto card aggregator. We compare 139 crypto debit and credit cards by real fees, custody type, region availability, network, and cashback structure. The hard problem we solve is the gap between marketing claims and actual fees: every issuer advertises low FX or high cashback, but the numbers in the fine print rarely match. Our calculator and side-by-side comparison tools show what a card actually costs based on your spending pattern. Built with Next.js 15, TypeScript, and a CSV-driven data model that lets us update card data faster than any database-backed competitor.
