Oxygen was a US fintech neobank founded in 2018 and a Y Combinator graduate, offering banking, debit-card, and financial products aimed at gig-economy workers, freelancers, small businesses, and entrepreneurs. Surfaced as a portfolio company of 500 Global and added to the API Evangelist network, the company's consumer services are currently unavailable ("we are working on new and exciting initiatives") and no public developer portal, API documentation, or machine-readable API surface could be found during enrichment. This profile is retained as a company lead with a live web presence but no active API program.
