Scale AI's secret sauce is in labeling lidar point clouds, which is really a necessity for the self-driving car industry. Sure, they can label other stuff as well, but it's not hard and there are other companies that can do it (not quite as well, but they could easily catch up).

What I'm trying to say is Scale AI is pretty much the only company offering a solution for an absolutely hair-on-fire problem for self-driving car companies - the introduction was unnecessary (and many of their customers are Argo, Waymo, Zoox, and other companies not affiliated with Y Combinator). Assuming the self-driving bubble deflates (it will) then Scale AI will suddenly find itself a commodity business as labeling images is not so hard that it can't be easily copied. It will be a race to the bottom. Unless there is another sudden surge of demand for labeling lidar point clouds.
