Welcome to TESOBE

We are the Berlin based software company behind the Open Bank Project, an open source API and App store for banks that empowers financial institutions to securely and rapidly enhance their digital offerings using an ecosystem of 3rd party applications and services.

We assist banks in executing effective API strategies by providing a proven API technology platform supported by an active community of developers and partners. We consult banks on API strategy, digital transformation and associated regulation e.g. PSD2.

Since 2005, we have developed numerous e-commerce, e-publishing, social network and financial web and mobile applications. We specialise in bespoke API development using Scala and Python.
