Appen, an AI firm that once helped train models for companies like Microsoft, Nvidia, and Google, has lost its Chief Revenue Officer and Chief Marketing Officer. Appen's CEO Armughan Ahmad resigned earlier this year shortly after Alphabet terminated all of its contracts with Appen. Appen's revenue dropped 30% in 2023 and 13% the year before, partly due to "challenging macro conditions." Former employees said Appen struggled to pivot to generative AI due to weak quality controls and a disjointed structure. Appen's stock has fallen 99% from its 2020 peak, losing billions in market value.
