About us

Why Nabla?

The idea of Nabla was born at Facebook AI Research, where Alexandre, Martin, Moustapha and Cijo worked together under Yann LeCun’s leadership. In this unique position where we were both immersed in the latest AI research and in contact with many businesses (Facebook’s partners and customers), we realized the gap between AI research and real-word applications and decided we wanted to bridge it.
