As a fellow belgian, I have been following you and segments closely. Congrats on being the first belgian YC company :).
From the beginning onwards I was wondering why you chose to put such an emphasis on segmentation labelling. Do you see this usecase as the Computer Vision application with the biggest (future) market or maybe the least saturated offering at the moment?
In a sense, image segmentation labels are strictly more informative than bounding box labels: you can trivially extract the containing bounding box from a segmentation mask. One big reason that segmentation labels are not used more often, is simply because they are too expensive. Labeling a bounding box requires only two clicks, while labeling a segmentation mask requires much more time with manual tools. We're trying to solve that problem.
In the future we want to dig even deeper into this problem, and expand our scope to video and 3D segmentation labeling. We believe there will be a huge need for such tools now that everyone is getting smartphones with Lidar and AR/VR capabilities in their pockets.
