The story

Oyster is a distributed HR / Employer of Record (EOR) platform founded in 2019 to help companies hire, pay, and provide benefits to full-time employees globally. Its embedded finance footprint is centered on global payroll payouts and contractor payments through a network of local payroll subprocessors, rather than owning a banking or card stack. Note: 'Oyster Financial' (Mexico SME finance platform, acquired by Yaydoo) is a distinct company and NOT this target.
