FYST

FYST is a fintech company headquartered in Riga, Latvia, that provides payments products and advisory services to businesses operating in cross-border ecommerce. Its core offering is a serverless payments product built on a Lambda-first architecture using AWS Serverless, designed to address the complexity of cross-border payment flows. The company also maintains an extensive global network of payment method providers and offers tailored advisory services to help clients scale internationally.

The technical stack reflects a deliberate architectural choice: the Lambda-first approach on AWS underpins FYST's focus on scalability, fraud prevention, and reliable payment method integrations across markets. The advisory arm draws on the company's network and domain expertise to guide businesses navigating the regulatory and operational challenges of global ecommerce payments.

FYST operates across the fintech, payments, and cross-border ecommerce verticals, with clients and ambitions that extend well beyond its Latvian base. The team is multicultural, drawn from over 20 countries, and the company places emphasis on results, ownership, and open collaboration. Performance is directly recognised and rewarded.
