Fifth Third is a 167-year-old national bank that has evolved from a traditional regional bank into a significant embedded finance infrastructure provider through its Newline platform. Rather than simply banking consumers and businesses directly, Fifth Third has leaned into becoming a sponsor bank and API infrastructure layer for fintechs and software platforms — most visibly through the 2024 Stripe Treasury partnership and the 2025 Brex commercial card deal. Newline grew fee revenue 53% in 2025, positioning the bank as one of the few legacy institutions successfully monetizing the embedded finance wave by sitting behind consumer-facing fintechs as the regulated balance sheet and rails provider.
