U.S. Bank, Mastercard take Amazon's small-business cards from Amex
2026-03-31 · lending
The Minneapolis-based bank will issue the cards, and Mastercard will act as the network provider. American Express formerly ran the e-commerce giant's business credit card programs.
Product Blueprint ClearSwitch — a B2B credit card migration intelligence platform that helps community banks and regional credit unions quickly build, price, and launch co-branded small business card programs to compete for the seller/merchant segments being reshuffled as Amazon moves from Amex to U.S. Bank/Mastercard. It ingests a bank's existing SMB portfolio data and generates underwriting parameters, reward structures, and onboarding flows tailored to specific merchant verticals.
Why it matters The Amazon–Amex split signals that even the largest co-brand relationships are now contestable, and the 30M+ U.S. small businesses underserved by big-bank card programs represent a reshuffling moment. Mastercard's new positioning as the Amazon network creates downstream pressure on Visa-aligned community banks to accelerate their own SMB card differentiation right now.
Target user VP of Product or Head of SMB Lending at a community bank or regional credit union with $500M–$5B in assets, frustrated that they lack the analytics and product tooling to launch competitive co-branded or private-label SMB card programs before larger players lock up the newly available merchant segments.
Go-to-market Sign 3 community banks in the Midwest (U.S. Bank's backyard) as design partners by offering a free 90-day portfolio analysis that benchmarks their current SMB card yield against projected co-brand structures — this is the MVP. Use those case studies to present at the ICBA conference circuit and close 10 paying customers at $2,500/month before building the full self-serve onboarding flow.
