This is interesting, but I think most enterprise AI buyers probably aren't looking to buy from the current batch; they're just too volatile at that stage. This does seem like an opportunity for cross-pollination where early start-ups get to test their product signals and enterprises get to see what's on the cutting edge.
This seems more beneficial to the founders because the the enterprises could instead just choose to do some research on the start-ups. It's not like the start-ups are keeping their knowledge quiet because for them to survive they need to convince everybody what their doing is meaningful.
