Financial Services São Paulo, SP 51–200 employees Founded 2018 Privately Held

alt.bank operates a turnkey credit card infrastructure for Brazilian banks and fintechs, built on Java, Spring Boot, and AWS. The stack is stable (no major tech migrations underway), and hiring has slowed to a crawl—only one role posted in the last 30 days across seven open positions. Pain points cluster heavily around fraud detection, delinquency management, and customer service scalability, suggesting the company is scaling operational friction rather than pure engineering velocity.
