Adrian Younge! He makes hip-hop inspired jazz with legends from both genres and cites Portishead as one of his most beloved inspirations.

There's also Supreme Beings of Leisure, who were lesser known contemporaries of Portishead. Lots of similarities here, but they generally explore a wider breadth of feels besides depressive longing, and their sound definitely reflects that. One of my personal all-time favorite bands, these guys. Right up there with Portishead!

Edit: Mazzy Star also comes to mind for their shared tone. More of a stripped down sound in comparison, and they lean more toward bluesy folk, alt rock, and occasionally gaze than triphop, but their lyrics should have a familiar feel to Portishead fans. They might be a bit disimilar on the surface, but they share a lot of the same spirit once you pop that hood up.
