Viva Wallet, now trading as Viva.com, is a Greek fintech company and neobank for businesses. The service covers payment acceptance and business banking across several European countries. Merchants can take card payments through payment terminals or an app on an Android phone, and follow payments and statements in an online dashboard. It is delivered as a cloud service; there is no self-hosted option and the software is not open source.
The company is headquartered in Greece and is controlled by Viva Wallet Holdings, which holds the majority of the shares. The US bank JPMorgan Chase has held a minority stake since 2022. According to Wikipedia, Viva holds a payment institution licence under PSD2 and a banking licence through VivaBank, which is supervised by the Bank of Greece. A European organisation therefore deals with a provider under European financial supervision. The sources consulted do not state where customer data is processed, so this is worth confirming with the vendor.
